Jump to: navigation, search

Importing and Exporting Rigs and Presets requires a USB flashdrive or other mass storage device. For more on hardware requirements and initial setup, see Other Hardware.


Rig Manager

Kemper has released a RigManager software that greatly reduces the effort needed to find, demo, import, and export rigs. Before spending too much time messing with USB sticks, try the software out. See the linked page for more details.

Importing Rigs

Importing New Rigs and Local Presets

The Profiler is able to automatically see all rigs and local presets (e.g. local presets of cabs) stored in the Shared folder of the USB stick; they will be imported regardless the sub-folder they are stored in and even if they are packed [as an archive file - .zip, .rar, .tar, etc.]. You could put a complete backup archive file into the Shared folder and import all rigs and local presets included in that backup.

  1. On your computer, put the rigs/presets you want to import in the Shared folder at the root of the USB drive.
  2. Plug the USB stick into the KPA. Once the KPA recognizes the USB stick, the third top button will show External Storage. Press it.
  3. Press Import

The Profiler will import any rigs and presets in the Shared folder that aren't an exact match for a rig/preset on the profiler.

Profile Management on the USB stick

Q: After I import profiles from my USB stick, should I delete them from the Shared Folder of my USB before adding additional profiles to be imported to my Profiler? Or do I leave them all in the Shared Folder for as long as I wish to have them in my Profiler?

A: guitarnet70 - Remove them after importing: if you edit the version on the Profiler it will re-import the old one the next time crating duplicates. Keep a copy on the computer, it is enough.

OTOH, if the rigs on the Profiler are the exact same as the ones on the USB, it will not import them again.

Importing thousands of rigs

I recommend you guys not to keep more than 1000 rigs in the machine. We are planning to introduce new features, which will require more memory space.


Favorite Rigs

You can create a sublist of rigs using the Favorite function.


 Rig -> Favorite.

Press and hold Rig to toggle the favorite state.

If a rig is a favorite or not, depends on the owner name of the Profiler. Setting the Favorite flag will store the owner name in the rig, this way you can share rigs without distributing the favorites state to everyone else. Setting it to your name as owner name will recover your favorites.

So a rig is a favorite, when the favorites tag matches the owner name of the Profiler. This way, you can transfer favorites between devices without mixing them up with favorites of another user.


Q: If I delete everything except favorites, will I lose all the cabs that I have save or changed in the rigs that are now in my favorites? And can I delete all but favorites and save all cabs as well?

A: timo - Amps and cabs are embedded in the rig. Deleting the rig means loosing the content incl. the amp and/or cab. You can store the amps and cabs separately as stack presets if you want just to keep those.

Favorite list appeared already filled with lots of profiles !

Q: When I import profiles, some of them seem to be automatically added to Favorite…

A: Checking the Store sets Fav. case in the System menu automatically sets as favorite any rig that you've stored (even only another name). Just uncheck it.


Autoload can be switched on and off. It is great to audition a series of profiles, but it is better off if you're just scrolling through searching for something.

Deleting Defective/Corrupted Profiles

In case of a defective profile making the system crash: when the Autoload option (the small box appearing at top right corner, when browsing profiles) is checked, the rig is loaded immediately as soon as the cursor is on that rig (profile). Uncheck the Autoload, locate the cursor at the profile, and delete it.

Scrolling through many Rigs

Another reason to want to switch Autoload off is when you want to pass through many profiles aiming an a specific one: this will make the rigs flowing much faster. In Browse mode (turning the Browse knob once) it is a matter of a single button switch.

If you just want to pass through rigs because you’re aiming at a specific one, disengaging Autoload will definitely speed the process up because rigs will not be loaded as soon as they are shown on the display. In Browse mode (turning the browse knob once) it is a matter of a single button switch.

Also, see the Rig Up/Down Buttons...

Rig Up/Down Buttons

If you selected to list the rigs alphabetically, the up/down buttons will take you to the next/previous character following the selection you've made. If you sort them “by amps”, they will take you to the next/previous amp in the list. This is for example useful when you have several variations of the same amp and want to quickly scroll among amps.

Exporting Rigs/Presets

The Profiler has two means to export rigs: export and backup.


Export can export the current or all rigs/presets as individual .kipr files on the USB drive.


Backup will create a single, time-stamped file that includes all rigs.

A more Convenient Way to Manage Large Amounts of Rigs

If you want to delete more than just a few rigs or local presets, the procedure can be time consuming on the Profiler. Many users are already aware, that it is possible to unpack Profiler backup archives and manage content on a PC or MAC. If you strictly follow the following instructions, there will be no risk of losing any of your precious sounds!

Profiler backup archives are based on a standard file format, tar. These archives can be unpacked with standard freeware like for example 7-zip, Zipeg, GuiTar, GNU-tar and others. We are recommending 7-zip for PC and GuiTar for MAC.

Unpacking a Profiler backup archive on your PC or MAC will give you free access to the folders containing the individual rig, snapshot, and local preset files included in the backup. The folder Stomp, for example, contains all your local presets for stomps, but obviously not the program code for the Profiler stomps. In this unpacked state of a Profiler backup on your computer you can easily select and delete rigs or local presets.

  1. make a backup of the rigs, and use an USB pen to export the .kpbackup into your computer;
  2. make another copy of the file, and change its extension to .rar or .zip;
  3. use any compressed archive manager (Total Commander, IZArc… or Stuffit on a Mac) to browse through the file folders;
  4. delete/add what you want to get rid of from the folders;
  5. once happy rename the file back to the backup again (.kpabackup), and import back.

You can also get rid of unwanted effect settings and amp or cabinet presets. There is no CRC control, otherwise the manipulated backup would be rejected. Avoid renaming the profiles on your computer though, unless you’re using a proprietary tool.

For detailed instructions on how to do this, see here.

Export vs. Backup

The Profiler has got a function to export rigs to the USB stick (Export all rigs). Unlike a backup, it does not export local presets and global settings; so a backup is complete, Export all rigs is not.

Exporting all rigs also takes much longer than a backup (a user with FW 1.1.0 has recorded 6h 20’ for his 2869 rigs!) since the file system on the USB sticks is not really good in handling lots of files. A backup wins here, too, since it is just one file.

Backing up FX Presets?

You cannot export to backup an fx preset. So here’s how to do it:

  1. Store your FX presets on your Profiler;
  2. Make a backup of your Profiler on your USB and transfer the backup file to your computer;
  3. Rename the suffix from .kpabackup to .tar and decompress it. You’ll see a folder structure for rigs, FX, etc; you can manage.

When re-importing FX to the Profiler you can do vice versa.

Deleting Rigs

Too many Rigs? Fast Delete & Restoration

Push the Soft button One (top left button above the display) while you switch on the Profiler and keep pushing until the message Maintenance Mode appears. As soon as the unit has started push the Maintenance button, then the Memory button, and then Init Flash. This will clean-up the internal flash memory.

Shut down and start again. There will be no rigs on your unit right now. Now you can Restore factory rigs (which will bring your Profiler into its initial state) or import some from the USB stick.

You can also

  1. Make a backup on the USB stick;
  2. open it on the pc with Winrar or Total Commander; or use IZarc on a Mac;
  3. erase the content of the Rig folder;
  4. save the Rig folder and replace the file on the USB;
  5. restore the backup. Done, the Profiler is empty.

For more information about the proper way to manage your backup file on a computer, see the chapter A more convenient way to manage large amounts of rigs later in this section.

A Faster Way to Delete Profiles from Inside the Profiler

Yes, we can use the computer to delete profiles - but the Profiler is fast as well.

If I test some profiles from an author - and found they do not work for me – I:

  1. select 'Current Author';
  2. switch to Browse Rig view - Switch Auto load off;
  3. press Delete and confirm; at this stage, I used to wait until the dialog box disappeared. But it's much faster to
  4. press the third soft button again (even if the dialog is still displayed). By doing this, I can delete many profiles in a few seconds.

Do Amps/Cabs Stay on Profiler if I Erase All Rigs?

Q: If I were to delete all of the rigs that came on the Profiler, would the associated amps and cabs be gone as well?

A: guitarnet70 - Yes, they would. You can still make a backup of everything and/or restore the factory rigs at any given moment.

A: timo - Yes, theay are gone. The amps/cabs aren't associated, they are embedded in the Rig. If you want to keep them solely, you can store them as local presets (Stack Preset). In this case, you can dial them up again at any time.

Errors in deleting rigs

Q: I've been deleting lots of rigs. Yesterday the count was showing me 1300 when I turned the Profiler off, today I start again and the count is at 1700 !! and I see some rigs I'm sure I had deleted.. as I'm deleting now I see the count lower 1 at a time.

A: timo - I assume that the actual rigs are deleted, yet, the data structures think they are still there. You can fix this by creating a backup and restore the Profiler from it right after it. During reboot, the sound content gets rescanned.

Renaming Tags

To rename the tags for the Amp or Cab block:

  1. Hold Amplifier or Cabinet for some time;
  2. Press the Show Tag soft key;
  3. Edit;
  4. …and don't forget to save ;)

To change Username in the full rig press

 Rig -> Show Tag ... 

Profile name, Author and comments can be edited from the unit. For the other fields, if you have a lot of rigs’ names to edit, upload them to the Rig Exchange and edit, then re-download. Delete in the Rig Exchange if it's a duplicate of another profile.

Also, see Copy and Paste...

Copy and Paste

The Copy function loads in memory the text of the selected field. You can paste it into another selected field by pushing the Paste button. But the Paste function keeps in memory 10 different character strings or copy instances, so if you push several times the Paste knob you have access to older copied data as well!

Since FW 1.5 They will be recalled from memory with a LIFO (last in, first out) logic.


Copy/Paste can also store the settings for any block, including Stomps, Stack, and Effects. So you can hold Cabinet on one rig, then hit Copy. Select another rig, and hold the Cabinet button again. Now press Paste, and you've copied over the cabinet profile and the cabinet parameter settings from the first rig to the second.

Also, see the Lock Button.

Creating a New Rig from Scratch

You can start with an empty rig:

delete all the entries of the amp & cabinet tags.The rig will not be empty (as in: no sound) but if this rig is used as a starting point when profiling, the post-profiling tagging starts out without entries.


When creating a new rig from scratch a trivial suggestion would be to choose an amp profile. Then start creating your new rig.

Just switch off the stomps and the fx with the dedicated soft buttons and use the lock function (press and hold Stomps, press again once, press Lock. Same thing for fx). Now you can browse through the amps only. When you want to add something just unlock the block and select the desired stomp or fx.

If you have updated the firmware to at least v 1.5.1, then you can browse through the amps without locking the stomp and effect sections: just press and hold the Amp button and then use the Browse knob.

This is the method I use to create a rig from scratch.

I created 3-4 blank rigs with all the buttons off but with preselected slots just ready to be switched on, so for example in the blank rig #1 I put:

  • SLOT1 = Gate
  • SLOT2 = Compressor
  • SLOT3 = Booster/overdrive
  • SLOT4 = Studio EQ
  • STACK = default blank stack
  • SLOT X = Graphic EQ
  • SLOT MOD = Chorus
  • SLOT DEL = Free delay with little feedback/time/mix and time around 300 ms,
  • SLOT REV = little hall rev.

The advantage is that all the stomps and effects are off but ready to be used with a simple knob turn. I put these blank rigs on the top of the rig list; from one of them I start searching for a stack preset among the 400 I carefully stored. The stack presets I have are really ordered by gain from cleans to crunches to drives to leads to metal sounds.

This way, I can create a true sounds which I'm looking for in less than 5 minutes, with great result. Last but not least, the rig is already tagged with my Profiler Owner Name and comments [For a complete description of this approach also see here in this document]

Here you have my rigs examples if someone wants to try. [1][2][3]


Presets vs. rigs browsing to build and store amps/sounds

Let me do some considerations on the using of presets, especially for the stacks. A rig consists of a complete stomps-amp-effects chain, but a lot of rigs have only the stack amp active. A stack preset has minor memory utilization than a rig (2,8 kB vs. 3,8), and moreover can be anytime recalled with a simple step.

It might be preferable for someone to use the presets instead of the rigs to save the profiles, and use the rig only when they want to tweak the sound to taste/needs.

My approach:

  • on the presets side I store my main stack amps, ordered by gain, with the pure sound of the amp profile;
  • on the rigs side I store the same amps, ordered by factory and tweaked (depending on the case, but at least with gate stomp, noise gate and a bit of reverb on; often with compressor, dist stomp and equalizer, sometimes with modulation effects).

When I want to build a sound I use one or both of the two following methods:

  • search for a rig among the ones available that match my sound, and tweak;
  • start from a blank rig (that I created with all the buttons off but ready to be activated with a simple knob turn), and then searching for stack/stomps/effects presets that match my sound… and tweak.

Here you can see a couple of my blank rigs:[4][5]

When you are searching for a sound and you are switching between several amps, it may become hard to choose the best one for our application. While browsing and tweaking amps, as soon as I realize that the sound can match my request, I simply save it as a snapshot. After this first passage I start listening to the snapshots and choose the final one… and tweak!

Here’re my presets, in case someone is interested in them [as of Oct, 2012). To install presets, just put them on the Shared USB folder (in the same way you already do with the rigs).

  • Stack presets (rar) (500 Stack Amps, almost the same content of the Amp rig file but tweaked and ordered in a different way, divided in 5 categories: Clean, Crunch, Drive, Lead, Metal);
  • Cabinet presets (110 cabs including And44 free and the famous Tills ones, all normalized in volume and with proper naming);
  • Tonestack presets (30 useful tonestacks ready to be used to tweak in a rapid way the amp tone);
  • Stomp presets (170 Stomp presets ordered by effect type and including the factory presets integrated with FW 1.6)
  • Delay and reverb presets already inside the default Profiler, ordered, and with some additions.

Browsing Cabs

Q: When choosing to browse cabs from rigs, instead of the cab from that specific rig the rig itself gets loaded, replacing the original rig where everything started out.

A: Be aware that only the cab gets loaded to the actual profile, as it’s expected. It’s just that the cab keeps the rig’s name.

Sharing Cabs

Q: How can I share a cab of a rig I profiled?

A: Just select the rig, go to the Cab section (Hold the Cabinet Button) and use the Store. Don’t forget to name it correctly cause you won’t be able to change that afterwards. You can now load the cab profile to the rig exchange.

Old program change map remains after restoring different amps

Q: I created a backup containing no profiles (I deleted all of the Rigs off of the USB drive via Windows, plugged it again in the Profiler and restored the backup. Worked great. A clean slate. What I didn't notice until I loaded some newer backups is that the Program Map names remained the same as the older backup not reflecting the new programs loaded. The only way I could make it work is by manually (in System) assigning the newer programs to the numbers overwriting the patch names (that no longer existed) in the Profiler.

A: Also delete the file MidiAssignments.xml at the root of the backup. It contains MIDI the program changes and should be deleted if there.

NOTE: for a creative use of the MidiAssignments file see the MIDI section. (Still to be written)

Sorting Rigs

Managing rigs is much needed since the amount of rigs is recently limited to 1000 units to be stored in the Browse mode of the Kemper Profiler. There are several ways to sort rigs:

  • All Rigs - All stored rigs on the Kemper Profiler are visible.
  • Current Author - Only rigs by the Author of the last selected rig will be displayed.
  • Favorites - Only those rigs marked as favorites will be displayed. To mark and un-mark rigs as favorites just hold the RIG button for two seconds.
  • Last Imported - Selecting this will display the last imported rigs. Very useful to check out the latest imported rigs to keep.
  • My Rigs - Shows all rigs generated by yourself. If your registered author name is "MeMyself&I" then all rigs by this author are shown.
  • By amp (<- This uses the Amp name tag; first entry of the amp tag)
  • By gain (<- This is very cool)

Of course there are several approaches to find out which rigs to keep and get the number of rigs down to a reasonable level.

Quick & Dirty via Favorites

This is the simple way. We are in browse mode. The upper left dial (Type) just below the gap is set to show "All Rigs". A quick way to get started is to play all rigs with your favorite guitar. Press the rig button for 2 sec to make the currently tested & liked rig a favourite. Once you went through all rigs, get your USB stick and perform a backup. Now use the browse knob to just show the "Favourites" and go through again. If the current one is no keeper just press the Rig button for 2 secs. How many rigs should you keep? Well, all the ones you like! If the list of "Favourites" rigs has changed (rigs got kicked out) make another backup on your stick. Please be aware that this "quick and dirty via favs way" might take days or even weeks. To be continued...

Renaming Profiles on the Computer

Q: I'd like to rename preset which I downloaded before I store them on my Profiler. Can I do that on my computer? Simply change the name?

A: Yes, but that is only the filename, not the one that is visualized on the Profiler. If you want to change that, you must do it on the Profiler or use a proprietary tool. See Tag Editor...

New Tag Editor

Some users have provided (WIP) a software tool to make tag editing easier and faster. See here for details.

Restoring Stock Profiles

Q: how I can get the stock profiles back?

A: Go to System, page one >> soft tab for Factory Rigs

My Rigs

My Rigs is a view that shows all rigs that have your name set as author. Your name is the owner of your Profiler’s name, while Author name is the one stored in the rig. So you cannot "move" anything to it. Views are not folders!

When you save a rig under a different name it doesn’t get listen under My rig, rather it becomes a favorite if the option in the system menu is set.


Importing Corrupt Rigs

From version 1.0.0 of the firmware, the Profiler is immune from corrupted profiles. They will just not load.

A Safety Tip

Before Importing profiles into your Profiler, check that every file you're importing is 4kb. If you find one that's 0 kB then it's a corrupt file and you must delete it. Also, a cab file must be 2 kB.

Saving Stomp/FX Presets

Q: Is it possible to save stomp setups? Like if I set up a specific flanger, can I save it under some name so I could use it again in a different rig?

A: Yes, you can save the whole current stomps or effects configuration as a single preset: press and hold Stomps or Effects and press Store. It will ask you whether you want to save the setup or the rig. You can have Stomps presets and Effects presets.

A: I just saved 10 effect presets onto a clean rig; this way I can go back and plug them into my rigs of choice.

A: It’s a great time saver when setting up gig presets!

Exporting Stomps/FX Presets

When you perform a backup, it includes your stomps and fx presets. All you have to do is to rename the backup files to tar or zip and unpack it. You'll see the presets in the appropriate folder.

USB Subfolders

Q: Is it OK to make sub-folders inside the shared folder for cabinets, Rig Pack 2, paid for profiles ect? Will the Profiler still recognize new additions?

A: Yes. During Import, all files (even in sub folders) are analyzed and sorted to the right locations. However they will certainly not keep this folder structure on the Profiler once imported.

List Based Rig Management

As long as there is no librarian SW available for your computer platform an alternative list based approach could be used. The idea is to create a list of all rigs in your rig collection. This list provides a better overview and can be used to organise your rigs.


How To Create The Rig List

Whatever system you use to organise your collection of rig files it should be located in one common base directory on your computer. For instructions how to transfer rigs from Kemper Profiler to computer see Reference Manual chapter "External Storage". All files in one base directory makes it easy to create a list of all Rig files with the help of the KIPR Tag Editor:

  1. Start KIPR Tag Editor
  2. Select menu: File - "Generate csv file from directory..."
  3. Select the base directory of your rig collection.
  4. The list/batch file "kipr_tag_editor_output_file.csv" will be generated in the base directory. See log output in right side window of KIPR Tag Editor.
  5. List file format is .csv (Comma Separated Values).
    The top row defines the tag types and the following rows the tag contents for each rig.

Rig List Use Cases

For easier handling the rig list csv file can be imported in your favourite spreadsheet program. For best compatibility import all columns in text format. Freeze the top row to keep the tag type definitions visible.

Sort And Search

The spreadsheet program's search and sort functions can be used to find the rigs you are interested in. e.g. sort by amp model, author, date, amp gain, etc. It would even be possible to sort by amp definition to identify modern and vintage amps.

Rename Rigs, Edit Tags

If some tag entries are inconsistent, misleading or simply missing they can be edited in the list. Search and replace could be used for multiple edits. Empty tags can be filled in directly in the spreadsheet.

Select Rigs From List

If you identified the rigs to be used in the Kemper all unwanted rig rows can be deleted from the list. Make sure the top row of the list is preserved. While batch processing the list in KIPR Tag Editor the rigs mentioned in the list are copied into a new directory. From there they could be transferred to the Kemper Profiler.

Batch Processing The Rig List

  1. The modified rig list has to be saved as csv file to be processed by the KIPR Tag Editor.
  2. Process the csv file in KIPR Tag Editor: menu File - "Batch process csv file..."
  3. A batch-<date> directory will be created containing the selected and modified .kipr files from the list.
  4. Copy files from batch directory to "Shared" directory on USB memory stick
  5. If only the selected rigs should be present delete all rigs on the Kemper Profiler.
  6. Unmount/eject USB stick from computer and plug into Kemper Profiler
  7. On Kemper Profiler import rigs from "External Storage".

Ordering & Renaming Rigs

Maurizio's Backup

Maurizio - I’ve developed a method to organize the rigs trying to override the following:

  • different profiles of the same amplifier, or different amplifiers with the same level of distortion, or different amps of the same brand were scattered all around in no order;
  • profiles of strongly tweaked amplifiers were mixed with simple profiles with no effects or with no tweaking and also with rigs that try to match particular song sounds;
  • acoustic and bass profiles mixed in open order;
  • completely different volumes among different amps and different rigs that complicate a lot the research of a sound and any comparison.

So that’s how I organized my rigs collection:

"Raw" Rigs with only Amp Present

Every rig where only the Amp section is present or there’s very little modification is named

 Brand Model GainLevel PUType


  • FEN Mach Crun NE: Fender amp, Machete model, crunch sound, best suitable for neck pickup;
  • MAR JTM45 Cl BR : Marshall amp, JTM45 model, clean sound, best suitable for bridge pickup.

All these rigs are now ordered with the same amp factory and then model and you have them one near the other to better compare the various sound. Moreover, I normalized the Volume RMS to be more comparable and in a way that you can exploit all the dynamic range without clipping the Output LED.

Stack Presets

For the same amps I ordered in the rigs, in the Stack Presets I save only the Stack section, and order by the type of sound (Clean, Crunch, Drive, Lead, Metal). These presets are normalized in RMS volume as well, by tweaking the Cabinet Volume.

 GainLevel Brand Model PUtype

When searching for a type of sound instead that for a type of amp, (say crunch) I can now scroll all the crunch sounds and with similar volumes.

Some example of Stack presets:

  • CR FEN Twin NE: crunch sound, Fender amp, Twin model, suitable for neck pickup;
  • DR Corn Harlequin BR: drive sound, Cornford amp, Harlequin model, suitable for bridge pickup.

Unfortunately, we don't have the possibility to share these presets unless we use the backup method that replaces all.

I also use the following conventions:

Tweaked Rigs

All the rigs created by strongly tweaking an amp start with a “$” symbol.

 $ Description

For example:

  • $ Walking Moon
  • $ Till’s Petrucci jaws
  • $ Strumming

Artist Rigs

All the rigs created to match the sound of a specific artist/song are named as

 # Artist Song Px

where Px is the pickup position used. For example:

  • # PF ComfortablyFirst F1: Pink Floyd, Comfortably Numb, First solo sound, Fender Strato Position 1 (bridge);
  • # GM StoryBlues G1: Gary Moore, Story of the Blues, Gibson position1 (bridge).

Acoustic, Bass, and Other Sounds

All the special rigs for acoustic, or bass, or virtual sound (like those from the VG-99) are named as “&”.

 & Description

For example:

  • & Piezo Acoustic1;
  • & MarkBass602

Blank Rigs

Finally, I created some blank presets where all the modules and effects are switched off: they’re ready for creating a sound from scratch or tweaking in a very user-friendly way. All these presets’ names start with !!, and appear at the beginning of the rigs list.

 !! Description

For example:

  •  !!_BLANK_RIG1_!!: Comp in position 1, gate2:1 in position 2, Overdrive in position 3, EQ in position X, Air Chorus in position MOD; Free Delay and Hall Reverb. All the fx are switched off, but ready to be tweaked in few seconds.

Download Link

I put the link to my Profiler backup file in my Original Post on the Kemper forum.

Be careful! Do a full backup before trying it, and also save all the rigs using the Export all rigs feature. This way, any rig created by you can easily be recovered.

Prepend '-' on Tweaked Profiles

One thing I realized is I never use a profile as is, and I might eventually end up using the same base profile multiple time but with different modification. That’s why I never modify the original profile: to be able to go back to the starting point. So, each time I want to map a profile to my MIDI controller I save a copy of it with a “-“ in front of it. This way I can quickly scan the profile I'm using and that I modified and I can easily as well go back to the original using the name.

If you re-save both profiles to be compared then sort them by date, they would be side-by-side at the end of the list. This way, all the profiles you edit lie together. It is a hassle to navigate between distant profiles in the list…

Appending a Number or Letter

I like to put a number at the end of a rig as I tweak, so that I can keep saving off new "versions" of my rigs to compare to earlier versions. Keep in mind that when sorting, rig1, rig2, rig3 ... rig10 will actually sort rig10 between rig1 and rig2 (rig1, rig10, rig2, rig3 ... rig9), so comparing won't move correctly. Take the extra seconds and use two characters - rig01, rig02, etc.
