I would like to add a vocal processor on the channels in recording vocals on my Tascam SX-1. I would like to hear those effects while recording and during playback before MIXDOWN. I’m going to use the TC Electronic M ONE Multi Effects Processor planning to use the effects send and effects return routing. Can someone who is using a similar unit tell me how I can make this work? My mind tells it’s possible. I just want more help. Thank you in advance. The unit has MIDI connection too. I don’t know how a 20 year unit will work with a more modern MIDI unit.
