I’ve got Midi Guitar 2 running as an audio unit plugin inside of Loopy Pro2 as the host. It works, but when I choose the External Midi Output, There is no MIDIFX option “MIDI OUTPUT”, only Transpose etc. I bought the two upgrades so I could trigger other synths with this setup. Is it supposed to work? or is it auto sending it somewhere? Also, strangely trying it Standalone I choose my Quad Cortex audio interface input 1, just like. in the Loopy pro case, but with Standalone I get no audio input from it with the same setup.
It doesn’t send the same way as it does for standalone.
Look for the AUv3 as a MIDI source in another location. In AUM, selecting a MIDI input source for an instrument shows a list of accessible devices including the instantiated MG2 AUv3’s output. It’ll be similar to that.
I don’t think audio input 1 (from the QC) is the D.I. channel. Anyway, I’d need a screenshot of your config to be sure what the problem is but start with the above info.
