You should be able to do this as all the knobs/parameters are MIDI CC-able. The standard Start/Stop/Record were already MIDI CC-able in the TimeFactor, so this will carry forward.
We're putting a slightly new spin on the reverse/speed control, in that all of that will all exist on the one Speed knob/parameter where the speed ranges from double speed reverse (all the way left) to double speed foward (all the way right), with everything in between (quantized by the speed resolution knob), and a full pause in the middle. Since knobs were always MIDI CC-able, you should be able to program this to do whatever you like. You could also use an expression pedal or an Aux switch, or any combination of the three.
