MIDI IMPLEMENTATION
MIDI CONTROLLER LIST
Some controllers adhere to the normal midi-specified use (e.g. modwheel, pan) but most are used arbitrarily and therefore
may clash with assignments of other products. We have tried to avoid misuse of some “standard” controllers which could
cause problems.
Unless noted, all controllers are transmitted and received. Unless notes all parameters have the range 0-127.
*** Denotes a signed value where 64 represents zero.
Unless noted, this is -64…0…+63 stored as 0…64…127.
Another example is -12…0…12 stored as 52…64…76.
--- Denotes controller is not used.
The term “pulse width” is properly applied when square wave is selected.
For other waveforms, read “pulse width” as “double waveform phase effect”.
Double waveform phase offset is zero when the signed pulse width position parameter is 64 (meaning 0).
Common parameters are transmitted and received on the Synth MIDI Channel, set in the Synth Global Menu on the XioSynth.

determines which parameter the NPRN message will control.
