I have a about if I could achieve the following with a synth ( Mopho Keyboard) that send MIDI via USB and Ableton ....
When I create an "external instrument " in Ableton , sending MIDI from Ableton to Synth works perfectly . I can send MIDI from Mopho to Ableton for " pressing" the keys of the piano and also to modify various parameters that the synth has to be modified. This gives me the option to create synth´s parameter automation in Ableton and the ability to send notes to the Mopho.
But when I have all these info in the "External Instrument" recorded, and I play the track... no Sound is sent to the Audio canal. Why could that happens?
In resume, I want to have the following: Synth -> Ableton & Ableton -> Synth
Here some Screeshots



As you can see every works perfectly, when I play the External Instrument Canal, no sound is sent to the Audio canal and also to the Audio Card
Thank you very much in advance !!!
