Out of order forwarding... This should have gone to the list also... Hi, Hmmm, how do you recon? A sidechain for a compressor may be an audio stream, but it's the "control" behaviour of that stream that is of interest, right? That should mean that it would be possible to extract just the behaviour and only distribute "that". But I may very well be misunderstanding, this is mostly theory for me, I haven't had much real practice with this kind of stuff. delay, An example: Recording a guitar in mono (Sounds dull). Easy way to make it more lively is to add an stereo effect, delay is my preference. For the above example a mono-->stereo plug would suffice, but stereo-->stereo is more versatile. Muse handles the mono->stereo conversion internally. As for parameters I'd like separate delays for left and right, apart from that I'm open for suggestions... I'm no pro, I learn as I try :). Ya, working mostly in MusE I'm somewhat limited in the number of solutions I can try. Currently MusE only supports basic features (pretty much modeled after Cubase). /Robert
