cheekybeermonk Posted September 7, 2020 Share Posted September 7, 2020 Hi Does anyone know if it’s possible to use the volume knob on the Helix LT to control the volume of a PC 112 plus when connected by L6 link AES/EBU digital cable The accepted wisdom is to set the Helix output to drive the PC 112 plus so the input light is yellow and then use the volume knob on the PC 112 plus , that’s not so easy when it’s tilted back and it would be much easer if the Helix LT volume know could control the PC 112 plus volume and not change the LT output level Any one worked out how do do that ?

rd2rk Posted September 7, 2020 Share Posted September 7, 2020 Well, you can't do that. BUT....the Output Level on the PC112+ can be controlled by MIDI using CC#7. If you're not using the on-board pedal for anything else, you can set it in Command Center to send MIDI CC#7. If you're already using it, you'll need a separate expression pedal.

cheekybeermonk Posted September 8, 2020 Author Share Posted September 8, 2020 Hi @rd2rk thanks will give that a try , can I send the midi signal via the AES/EBU digital cable or do I need to also connect up an actual midi cable ? Could I create a Preset that only sets the PC 112 plus volume and then once set would the volume remain at that level when switching presets ?

rd2rk Posted September 8, 2020 Share Posted September 8, 2020 Not yet, but hoping the next update will fix that. Meantime you'll need a separate midi cable. You can create a preset to set the level using an Instant Command, and the level will remain the same between presets until you change it, but unless your presets are perfectly leveled, that won't be very useful.

cheekybeermonk Posted September 8, 2020 Author Share Posted September 8, 2020 It worked like a charm, thanks , is there anyway to get a visual indicator of the current sent value , I found I had to limit the max to about 90 so around 3/4 max volume to give a bit of finesse Quote Link to comment Share on other sites More sharing options...

Unless you're tethered to a computer, then you could use a MID Monitor. 1 Quote Link to comment Share on other sites More sharing options...
