i think it helps to look at if you will use the features and the stuff the octatrack is good at for your drums. i use the octatrack for percussion, but pretty differently than i would use a drum machine or mpc.
imo:
scenes
using synthesis and effects to make drums out of anything
cutting up and shuffling loops so they aren’t loops. with the octatrack i think of them more as grooves or feels or tone palettes. i start with single hits often enough, but when i have some thing i like i resample and take it from there.
making percussion out of live input
poly rhythms/multiple time scales per track, track resizing live.
“dynamic performace” lol changing things up on the fly with scenes and parts, one shot trigs.
otoh, if you want to do something like load 100 single hit samples and sit down and meticulously sequence and lock them, imo you could do it, but i don’t particularly like the octatrack for it, i don’t find the feature set super useful for working like this it feels like fighting the machine. to me, the point of the octatrack is more that i get to skip working like this if i don’t feel like it and do something more quickly or interactive. the flip side to that is i’ll spend more time practicing playing live.
i used to run my drum machines though a few other machines and effects to accomplish the same thing i do now, so i like it a lot.
i do find the MIDI side of it works pretty well for sequencing percussion in a somewhat more traditional drum machine style, but i’ll still leave most of the detail and variations for when i run that into the audio side of the octatrack.
