OK, I'll try explaining again and just bear in mind that IndePro is multitimbral sampler, meaning it supports more then one layer (instrument) to be played in the same instance of program, while those instruments can be assigned to separate midi channels and routed to separate stereo outputs (8 in total). I have Roland A800 Pro, it that's of any significance. So for example:
I have midi track 1 and audio track 1 in Sonar; I have layer 1 in IndePro on midi channel 1; Strings Sus are loaded in Layer 1; midi IN on midi track 1 is set to A-PRO MIDI Ch. 1, midi OUT is set to Independence 1 (where 1 means there is only one instance of Independence active, I can have several of them, but that would burden CPU and isn't necessary, since Inde is multitimbral); audio IN on audio track 1 is set to Inde Stereo 1 and audio OUT to Master. And then I record something there, no problem, everything plays as expected.
Then I add midi track 2 and audio track 2, another layer - layer 2 in IndePro, load Strings Pizz in Layer 2 on midi channel 2; midi IN on this track is set to A-PRO MIDI Ch. 2, midi OUT to Independence 1 (as explained before why Inde 1), audio IN on audio track 2 is set to Inde Stereo 2 and audio OUT to Master. If I record or play something in midi track 2, no problem as well, everything works just as expected. BUT! If I copy midi clip recorded with Strings Sus in midi track 1 (and by "copy" I mean Edit-Copy-Paste, or Drag-Copy, or Smart-tool-Move-Ctrl-Drag, all methods yield the same result) to midi track 2, expecting it to play Strings Pizz, it doesn't do that - it keeps playing Strings Sus and meter in audio track 1 is live with activity. While, normaly, it should play Strings Pizz and meter in audio track 2 should be live.
I've tried recording in midi track where Cakewalk Sound Center was used and copying the recorded clip to another midi track where SI- String Section was used - everything works just fine, in first track Cakewalk Sound Center is playing, in another track SI-String Section is playing copied clip. No problems.
So. I do understand there is probably no one among all of you using Independence Pro (former YellowTools, now Magix), but I can't afford Kontakt and Independence Pro is actually excellent sampler and library. I just don't understand why this is happening and it's slowing my workflow tremendeously.
Once again, thanks guys for your support, this is a great place to be.
