The Roland FI2K5-1 is a 45-key, light-weighted keyboard controller designed to control MIDI sound modules. It features flexible wheels and buttons that can be assigned various functions, such as modulation, volume, and aftertouch, allowing for maximum performance control with a minimum number of controls. The device supports features like After Touch, Key Velocity, and Poly/Mono modes.
The function you have set is retained even if the Axis is turned off.
