Yikes, that *is* complicated. I am rushing off to work now so I can't really apply my mind. But
(1) Remember that you can set the 'audio from' in any normal track to take audio from the return buses as well
(2) You can also use a compressor as a router. This is a trick I learned just this week from Khazul and TomViolenz Like so:
- in the track to which you want audio to go, put a compressor. Set it on sidechain. Choose the track from which you want audio to come in the input selector for the sidechain. Now set it to listen. Now audio will come through from the selected channel as if you had routed it there
- if you want audio to come through from external sources, or from other tracks sending audio, rack the compressor and create an extra chain. Leave it empty. This ensures that audio coming through from other sources is not blocked by your listening compressor
What baffles me is your need to have the audio sent back to the original channel. I don't know how you are going to do that with more than one audio source *and* keep them separate
One way might be to create a bus with your effect; rack it, link the parameters you want to control to the macros - and then duplicate the effect within the rack. You now have multiple instances of the same effect all controlled by the macros on the rack. This gets you past the problem of mirroring changes in the effect. Then set each rack to the desired audio channel using the compressor listening trick; and then use the same trick to pick up the audio as it comes out of the rack. But it scrambles my brain just to think about it.
P.S - Can you describe the routing you want in more detail? This may even require a diagram
) and I want to be able to choose which track to apply the FX to on the fly, quickly, with my PCR 300 controller(it has knobs, faders, pads etc.)
