This is really nice.
So far I only experimented with Elektron on-board FX and one pedal (w/o semd-return). I see for dub mixer send return fx is crucial.
However, due to limited space I opted for a 1010 BlueBox that has one additional output which means one send/return. You think this is enough?
Well, there is the CUE pre-fader but then I lose my headphone transition dj-style stuff…
