I own 2 x L1 Model II with a T1 each. In theory I can record 6 live instruments/mics in real time into my recording software on 6 editable tracks. I just connect 3 instruments one each to input 1,2,3 of each T1. From there the signals should go via output 1,2,3 to the 6 inputs of my Midi device. But - nothing arrives at the Midi. The T1 Prefs only allow to re-route to the Aux, Master and USB. Where do I control output 1,2,3 ?
