Notes are typically associated with MIDI controllers/keyboards or drum machines (or e-kits). For guitar, MIDI is useful to control devices, switching patches, switching effects on/off, or controlling effect parameters. PC's are used for changing patches, while CC's toggle and manipulate parameters. However, keyboards often come equipped with controllers that are designed to send CC messages - pitch and mod wheels, rotary dials, and sliders. As well as non-piano format notes: tap pads, and buttons.
===== NRPN (Non-Registered Parameter Numbers) =====
'''NRPN''' messages are special sequences of CC messages designed to access parameters on devices that have more than 128 parameters (max address size of a standard 7-bit CC message) or has parameters that do not correspond to the standard usage of the 128 available CC addresses.
