Multiple MIDI Controllers and Channels with Kontakt 8

Christopher Frith

I set up Kontakt 8 to play live with a Yamaha CHX-1 organ as MIDI controller and Xotopad app to automate volume ON/OFF for instruments in the rack. Xotopad works great using LOOPBe1 on same laptop as MIDI B controller and Yamaha organ as MIDI A controller. I have Kontakt instruments set to either MIDI Ch1 or MIDI CH2 for note on/off to set which keyboard they play on. Here is the challenge:

Volume control changes from Yamaha CHX-1 organ are sent on MIDI channel 16. How do I automate the Kontakt Amplifier control for instrument volume on every instrument in my rack? Setting instruments to OMNI means they play on both keyboards simultaneously. Not the outcome I want. Could a script be written for Kontakt that would route volume changes coming from the Yamaha organ on MIDI Ch16 to MIDI Ch1 and MIDI Ch2 so Kontakt instruments listening on those channels for note on/off also receive the volume control messages from the expression shoe on the organ coming from MIDI Ch16?

There are factory multiscripts that will do this kind of thing. Have a look at them (Rack view>KSP>preset>factory>transform). However if I understand you correctly, I don't think there is a factory multiscript that will duplicate a message to two channels, so you probably need a custom script.

This will convert any cc message on any channel to both channels 1 and 2. (KSP>Edit, paste text, click Apply)

on midi_in

 if ($MIDI_COMMAND = $MIDI_COMMAND_CC)

  ignore_midi

  set_midi(0, $MIDI_COMMAND_CC, $MIDI_BYTE_1, $MIDI_BYTE_2)

  set_midi(1, $MIDI_COMMAND_CC, $MIDI_BYTE_1, $MIDI_BYTE_2)

 end if

end on
