I'm from Octatrack camp. But i always look in ensoniq/emu/creative direction. Though i look at OT as modern times ASR10 but faster (ui- and cpu- wise).
Recently i was messing with such setup: Micromodular with Boss RSD10 as delay/sampler send/return and both are controlled with OT. MM sends audio to RSD + some feedback with phase manipulations + its 4 delays matrix in MM PolyArea then all that 'tank' is routed into OT. + OT controls RSD's delay and trig inputs via 2 flex slots loaded with single-cycle pulses which could be offsetted and so on. I'd say Boss RSD10 is pretty esoteric. https://clyp.it/gw2xvw4l
