I think side chain would be a programmable feature in the current OT.
The question is: can the recordbuffer be read out , and interpreted. Problem would be probably the read ahead. As there is a delay compensation that should also be possible. I don’t see a reason why the compressor should not get a side chain option when I can re sample internally anyway.
I would also love a mixer with programmable midi sequencer and programmable FX with P locks on the mixer, that would be awesome.
Ideally the FX units would get also programmable macro controls.
At the End it should probably be the OT MK 3, with mixer faders, and an extra FX section with probably analogue FX, with extensive control possibility’s.
Internal (replacable SSD) and option to record on the HD.
Well, i think at a certain point the problem might be, if this gets to expensive, they don’t get as many users buying into the system. 2000 €, probably with an upgrade slot, so you could add later some more DSP or Analogue Modules to it.
