Two things, not sure how well they work for all cases.
There’s a tool that will split a single track into multiple tracks based on assorted properties: https://www.renoise.com/tools/split-into-separate-tracks
You can also record to different tracks right from the start if your drum-pad can be set to send each pad on a different channel. You can the create separate instruments that a) only listen for MIDI on a given channel, and b) are coupled to a specific track.
I did this just now with my Akai MPK mini. First I set up two instruments (both using the same drum kit, bit you can use any instrument , I picked the same for ease of testing).
On the first instrument I set the MIDI input to the MPK on ch 1, and coupled the instrument to track 1.
On the second instrument set the MIDI input to the MPK on ch 2, and coupled the instrument to track 2.
I also programmed the MPK to have the pas use ch 2 and the keyboard channel 1. (The MPK mini only gives channel options for the pads as a whole and the keys as a whole.)
When I recorded my playing on the MPK, all pad notes (kicks, mostly) went to track 2, and all keyboard notes went to track 1.
I would think that if you are using the same instrument for each channel assignment like this you might just as well use the track-splitting tool. Seems like less work. If you want each channel to apply to a different instrument altogether, while playing, then channel/track assignment might be better.
