Thank you all for answering! I thought I would be locked into a soliloquy. I’m not familar with the forum. I would like to answer every one individually but it seems I can’t do it.
It’s seems from your comments it’s an Elements (Artist?) limitation. But there are great suggestions to try out.
Of course I can record each instrument on a midi track and render the mix. No problem there. And Elements is sufficient for my day to day purpose, with great compression, equalization, mastering plugins. And the Simon Phillips jazz drum pack.
I usually record acoustic instruments (guitar, bass, sax, snare) on audio tracks one by one (obviously!), the piano being the only instrument I record on a midi track which I sometimes edit. And the Phillps drum track.
But I feel midi recording and editing steals the “live” feeling. I tried to use Audacity to record everything in a single track. It won’t work in Windows (easily done In linux with Jack audio server). It’s a Windows’ limitation. It may seem a strange way of doing things but I’m not the only one trying to find a way of recording the output of VST instruments to an audio track (besides rendering).
Svennilenni confirms there’s no bus solution. I thought I was missing something or that there was some tweak available. I did my homework before posting. In Pro, you either route the VST instruments to a group track. Then you route the group track to an audio track. Alternatively. you create a dummy bus, route the VST instruments to the dummy and the dummy to an audio track. Quite simple. But in Elements (some say even in Artist), an audio track allows only mono left or right and stereo as input. By channel, I presume telecode means an audio track.
Peakae’s solution is a good idea. Replugging the ouput of 3+4 as input to the focusrite, with the caveats.
I’m not sure a mixer (I was considering a Yamaha MG mixer) would solve the problem. You can’t plug in VST intruments into a mixer. Pluging the 1+2 output into a mixer? Would’nt there be a a feedback loop? Maybe not if the 3+4 are plugged back into the mixer since the mixer would output to 1+2. It would be similar to peakea’s solution. I’ll ask my mixer salesman.
Thank you all once again.
