Keyboard split to different MIDI channels

[DJISF]

Hello! I'm getting an SP404 Mk2, and its MIDI implementation is a bit odd. Each bank on the SP404 Mk2 responds to the same 16 MIDI notes, but on a different MIDI channel. I was wondering if I could use the keyboard split feature to get access to more banks using one MIDI channel. Any ideas on how I would achieve this?

Thanks!
