Hi, I want a filter sweep to start when I tap my footswitch. So far, I’m using GS DSP’s MMMm plugin to generate a midi LFO (CC74), which I want to assign to a widget controlling the filter plugin.
The catch is that I can’t figure out how to make the widget listen to midi that originates inside GP.
I’ve only been using GP for a week, so maybe there’s an obvious answer here.
That’s an advanced feature. Route the GS DSP MIDI to the Gig Performer Midi Out Local GP Port. That essentially makes the MIDI messages look like they’re coming from “outside”.
Then you can associate a GP Widget to the Local GP Port “device” and then the widget will respond to those generated MIDI messages.
Important caveat: make sure you do not use a MIDI In OMNI block in your rackspace because it will receive those messages from the Local GP Port as well and then those messages will also pass into other plugins, which you don’t want!
Ok, thanks. Is there no way to have any sort of envelope generator control another plugin in GP essentials?
You won’t find the Local GP Port in GP Essentials. As @dhj mentioned, what you’re looking to do is an advanced routing feature and that functionality will only be found in the Pro version.
If you have virtual MIDI ports available from third party sources like Bome or loopMIDI, you can route them to accomplish what you’re looking to do, using the technique described above.
