I have a computer with a keyboard synthesizer. I created 2 MIDI tracks. On each of them I added a virtual instrument, and I assigned a channel number to each of them (track one, channel 1 of my device, track two, channel 2 ...).
My problem is: when I select (I click on) Track 1 and I played on the synth, all is ok. when I select track 2 and I played on the synth, I hear the track 1 (and not the 2).
In other words, I have to manually change the channel from the synthesizer (set it to 2) to hear the track 2.
The twelve o'clock output Seems To be configured Correctly ...
In fact, I could simplify my question, I realized that the 'problem' is the same with the virtual keyboard: whatever the chosen track the midi channel must be changed manually.
