OK, but which other machine out there does both of those things at the same time, on eight individually configurable tracks?

personally, i use the OT mostly for midi/audio combos with external gear (like you). i could not do these things live (i.e. Volca trio + TR-8 + OT as master/hub) without a full-blown midi/audio interface and a laptop on stage… (and MIDI clock would be a lot less stable, as well as more latency overall) I think you might miss the OT, once you get something like the TR-8, which is a fine unit, but very “dumb” without an OT to teach it some tricks.

i wouldn’t sell the OT – i’d sell maschine first… probably the akai and e-mu too, although they both have very good filters and AD/DAs for being rather old samplers! (used to own an E4K)
