Actually changed mine to be more specific:
Realistically that would cover all the bases (and bass’s) and give a shit ton of flexibility as all 3 can be used as pretty good fx boxes too.
OT for the stems, mangling, sampling, mixing.
AK for analog sounds, that delay, filterbank, keys
MC-707 for drum/dialog samples, all those rompler/roland sounds, fx, additional mixing.
Additionally I think it would be a pretty easy setup to handle, gives good sequencing flexibility, and is pretty hands on. The OT and 707 are compatible wrt samples, the AK with multimap can give a lot of power for both production and performing. 707 has excellent fx, eq, compressors etc.
Edit: Oh and a patchbay and maybe a small mixer for routing.
