I control my setup from Ableton Live (not via Overbridge) with Push 2 via E-RM Multiclock all in sync.
The advantage is that, beside the normal Live possibilities (Audio-,Midi Tracks, Effects, PlugIns), in Live I use 3 Midi out tracks (A4, OT und AR) with clips only containing prog changes. So I can flexible change via Push the patterns on the 3 Elektron machines over time. I can also automate it by Live follow action.
For a Gig I have only one Live Project which contains the whole concert stuff i can flexible play with push plus twisting the knobs and the fader on the Elektrons, effect boxes and my lovley Virus TI.
