Hi Anthony, I see now what you mean, you are mocking up a continuous music bed on the mixer and then you want to cut in segments of it into a looper so you can prepare new audio on the mixer to add? Of course the two streams must be in sync then. I know that at least the RME interfaces can be MIDI controlled, but I'm not sure how fast a channel mute is applied in the Fireface Mixer and I have not used that feature myself. If you could assign the same MIDI event to switch between muted/open on the RME and for controlling the looper you might have a chance... but thinking about that gives me bad feeling in my stomach ;-) Probably it would be better to handle all that routing and muting in Live. *IF* you are syncing Live you may look into the "MIDI Clopck Sync Delay" control in its preferences, just to trim the mixer and Live to run together. But be aware that Live in itself doesn't provide rock steady timing because it isn't a DAW by design but rather a live remixing tool (if offering solid timing all the live routing etc in performance would be too slow for the real world). And MIDI Clock isn't stable either, because the slaving device has to constantly speed up or slow down to adjust its tempo. I revisited the previous posts in this thread and wasn't able to find out where you are taking the sync master clock from? In case you are syncing Ableton Live (i.e. running it as a slave following MIDI Clock or MTC) the entire latency compensation system of Live's doesn't work. >From this comes that the Looper plugin will also differ in timing compared to your mixer audio stream and you will experience an un-sexy bump in timing when muting the original audio to let in the loop. A solution can be to use a third-party looping plugin like Mobius that in itself does latency compensation; moving new layers added to the loop a little bit in time for the first playback round (has to match the AD/DA latency of the full system, but you can dial in latency compensation manually by ear in Mobius). Also, it is not clear what you are meaning when writing "quantization"? In looping quantization means a given command is to be applied to the looper at a given point in time after you have actually pushed the button/pedal. But in a DAW quantization means moving a recorded audio file playback in time.
