Oh, that made me think of another scenario…. If both presets are in series on path 1 (mono in / mono out), Is it a mono signal the whole way or does it process preset A in stereo send it in stereo to Preset B for stereo processing and THEN down mix for output?

So, imagine a Harmonizer algorithm to a delay algorithm….  Does pitch A get Delay A and Pitch B get delay B or do pitch A and Pitch B get down mixed before being sent to the delay?
