Just reading through this....wouldn't the reverb disappear because you cancelled the original mono wave by inverting one side of a mono track?
no, it' not that.
the track doesn't intelligently send 'as mono', In Live's internal bussing it's sent as a stereo signal (to preserve pot panning), the reverb then receives L = -Mono R=+mono and should (in a stereo effect) process both of those individually before passing them to the chorusing dept. It should not sum them and then attempt to process.
anyway - I forgot, there's a better demonstration:
1: get ANY wave, stereo / mono / whatever ... no need for a utility
2: send it to the same big reverb as before (100% wet) turn off all chorus and spin. stereo set to 100 (default)
3: pan the origin channel hard left and right
the reverb stays central. I think the reverb is mono
further tests to eliminate the pan pot (ie are sends post fader pre pan pot?)
1: take a stereo test wave which is first 100% right, then 100% left (I re-sampled a drum loop hard panning 1 bar left, 1 bar right )
2: play back the re-sampled panning wave, send it to the reverb
3: set the reverb send as 'prefade'
4: turn down the panning wave and listen to the reverb
the mono signal is still evident from a hard panning origin, despite eliminating as much of the track signal chain as possible.
I think it's a mono reverb
