MIDI Guitar and AU version
.
An important piece of information regarding the usage of MIDI Guitar and Gig Performer on macOS.
The VST version works as expected. You insert it into your rackspace, connect your guitar to its audio input channel and your MIDI data comes out of its MIDI port. You can of course do this in as many rackspaces as you want.
However, the AU version does not produce MIDI on the MIDI out channel. Instead, it creates a new virtual MIDI Output port and you will then need to create a corresponding MIDI In Block to receive MIDI from the MIDI Guitar plugin. Doable but rather extra unnecessary work.
In short, prefer the VST version over the AU version.
