Helix MIDI out Program Changes to Boss SY-200 in Helix Posted February 11 There seems to be a lot of Helix vs Boss SY vs Midi experience on this trail, so I'll pitch my question and I'd appreciate any suggestions on it please. I use Helix floor, and recently, an additional SY300 in a stereo FX loop from the Helix. Works well to add a subtle pseudo keyboard player or synth lead lines for my covers band. So here's the challenge.......In adding a synth pad layer for a new song this week, I also layered in the sequencer on the SY to give it some rhythmic 'movement', but there is a section in the song where I want that sequencer switched off. I've set one of the SY Ctl footswitches to do this, but would much rather control it from a Helix foot switch with a midi message from the control centre, in the same way I have set up patch changes to happen on the SY automatically as I change patches on the Helix (I take a 'patch per song' approach to life...). So, does anyone know the approach I could take in control centre to do this, and also what Midi CC# I might use, if indeed that is the approach, or if this is even possible. The SY change we trying to do here is OSC1 SEQ ON/OFF if that helps. Thanks as ever, you wonderful people!
