Multi-channel MIDI Recording
To record several channels of one MIDI input to separate tracks:
Method 1 - Use a dedicated MIDI channel filter plugin before each track's input. Pictured here is midiChs_noGUI, part of the pizmidi pack.
Method 2 - Before each track's input, use any MIDI plugin that can pass the MIDI through unchanged, and use the "M.Ch" control in each plugin's window.
By default, every MIDI track will have its output channel set to 1. To record the actual channel instead, set each track's M.Ch to "blank."
