We're not in the 80's now and even in the late 80's a workstation was practical (think Korg M1). I mean Oldfield did pretty well with them and an ST.
Triton has assignable knobs and pages and pages of virtual knobs which are trivial to change. If you really want you can stick a MIDI knob box in the back of it and associate those to a virtual control including parameters equivalent to the 808's.
Triton has multiple outs and multiple internal busses. Think of it as a 120 note polyphonic synth with 16 part timbrality, built in rack of effects, built in sequencer, built in sampler and a full size studio mixer and half a hard disk recorder (TBH I use an external DAT because they're bomb proof). Plus it burns and rips CDs and loads Akai samples off floppies and CDs. It's a whole pile of awesome which fits in a flight case.
My rhythm is naff enough that the Triton's sequencer has the resolution to pick it up. If I really want to, which as per you I don't, I can quantize on the device and get it perfect. Then I can assign patterns to keys and play them with my left hand while I hammer out a lead with the right hand.
