Roland KR-107 Digital Intelligent PianoMIDI Implementation User's Manual
Summary
This manual provides comprehensive technical specifications for the MIDI implementation of a digital piano, detailing how various sound and control parameters are managed via specific messages. It covers advanced operational controls such as Modulation Depth, Portamento Time, Volume balance, Pan, Expression, and Flanger effects. This guide is essential for MIDI system integrators, developers, and technicians who need to program or troubleshoot complex external audio equipment to ensure seamless communication with the instrument's sophisticated features.

The velocity values of Note Off messages are ignored. This adjusts the rate of pitch change when Portamento is ON or when using the Portamento Control. A value of 0 results in the fastest change.

Not received when Rx.POLY PRESSURE (PAf) = OFF. (Initial value is ON)
❍Pan (Controller number 10)

The value specified by a Control Change message will not be reset even by a Program Change, etc.
For Rhythm Parts, this is a relative adjustment of each Instrument’s pan setting. Some Tones are not capable of being panned all the way to the left or right.
