I am trying to do a 4 chnl setup in Ableton. This is possible if I choose one audio-channel with the normal master-out that is routed to chnl 1-2. Then I open a second audio-chnl and assign this to ext-out 3-4. I created to m4l patches: the master-patch contains my generator and the spatialisation-logic: signal 1+2 is mounted to the normal plugout (master 1-2). signal 3+4 is connected to two plugsends (rear3 and rear4). The second channel in ableton contains a m4l patch with this named plugrecieves~.
Here is the problem:
Only if I open both patches in the Max-Environment the plugsend/receive implementation is working.
Is there a possibility to use this technology without openening both patches in max?
Thanks in advance
