Digitone sequencer with external midi keyboard

Hey Guys,

I have Moog Matriarch and I disconnected its keyboard, pitch wheel, and mod wheel from the synthesizer itself to use as a midi controller for Digitone via midi cable. It works perfectly for the Digitone tracks: CV, Velocity and Aftertouch, Pitch wheel, and Mod wheel are transferred properly.

As far as I still want to use this keyboard, pitch wheel, and mod wheel to play Matriarch I have connected a Digitone to Matriach through one of the Digitone’s midi track via midi cable. It works well: CV, Velocity, and Aftertouch is mainly transferred Matriarch keaboard to Digitone and then back from Digitone to Matriarch synth engine itself. But for some reason, I am not getting back to Matriach enginge Pitch wheel and Mod wheel midi data.

Any suggestion on what I forgot to set on Digitone or doing wrong?

Thank you all in advance!
