On my keyboard, I have a turn knob to select the MIDI channel that goes out.
In Cubase I have filled a Halion Sonic SE3 VST instrument with 5 instrument patches (trumpet, piano etc.). I have assigned them MIDI channel 1 to 5
By turning the knob on my keyboard I can then select and then play on my keyboard each one of the 5 patches, except the patch on channel 1, although channel 1 is clearly selected on my keyboard.
Why doesn’t Cubase pick up channel 1?
