I frequently use Hold Instrument, Switch to Guitar in MG2 for gigs. Recently, I moved to using my iPad and MG2 or MG3 beta. I have tried the Sustainer with all available options without any sustain at all (not even piano like sustain). I’m using the Boss EV-1 WL expression pedal and a Boss FC-6 footswitch. I have the left footswitch set to momentary and the right to latch. It works great when using my computer and MG. On my iPad, I can see that MG3 is seeing my pedal and the signal from the footswitch (MIDI activity in the lower left portion of the screen) I connected patch cable, and the Sustainer seems to be activating (ring around “footswitch” lights up) but no sustain at all. What am I doing wrong. Does MG3 not support this feature from MG2? Thank you.
Please correct me if I’m not understanding your scenario properly, but it sounds like you’re trying to reproduce the MG2 “hold instrument” behavior, where effectively you’d “freeze” your Instrument sound and allow the guitar to pass thru, in MG3.
With the MG3 architecture you’d need to have two Chains to do this, one for the passthru guitar audio, and a separate Chain for the synth/Instrument sound. (These mix at the Mixer Module, and then proceed thru the Master chain at the end.)
If “Chain 1” is the guitar audio, and “Chain 2” is the synth, you’d set up the individual sound you want for each Chain, and then you would add a Sustainer Module only to Chain 2 (not to the Master Chain, I’ve made that mistake before), set to “Freeze Chord”, and hook up a footswitch as desired.
That should, I think, allow you to play guitar and synth simultaneously, and then when you hit the footswitch, you should get a “freeze” on Chain 2 while Chain 1 is unaffected.
Now…if the above is what you’ve got set up already, and still are not getting the response you expect, could you share some more details about your setup? Are you running Mac/Windows/iOS, MG3 in standalone or as a plugin, which plugin host, etc?
If the above does get you up and running, hopefully you’ll quickly see how you might improve or enhance that basic setup. You could have both Chains running the same Instrument, for example; then, you’d really be holding/freezing something and then playing the same sound over that. Or, you could mute Chain 1 while establishing the chord on Chain 2, and then when you freeze Chain 2 you simultaneously unmute Chain 1 to allow it to pass thru. And so on.
