Do you need a pitch plugin which handles the left and right of a stereo signal differently ?
If not, just slap rubberband stereo pitch shifter (ladspa) on a stereo track.
I have for example 3 tracks, one mono and two stereo. Each track contains the same audio but recorded by different microphones. I need to change the playback rate of individual regions on the tracks in order to adjust their pitch without affecting (much) the phase relationship of the three microphones.
Can rubber band work across multiple tracks? Or with a 5 channel audio file?

I wonder if it would be simpler to adapt the rate adjustment plugin that comes with Ardour. It doesn't report its latency and it doesn't have a pitch value to rate value conversion.
