Thanks for your reply
I have many multi tambral synths, and some have many outputs.
Let’s say I want to use my ESQ1. It wouldn’t be unusual for me to want to use more than one sound on it at a time via different midi channels. I’m not sure how to have multiple midi tracks on different channels within a vst external instrument track. I know how I could do it with multiple midi tracks all targeting the ESQ1. Then I could record the audio from each different voice to seperate audio tracks for mixing and processing.
I’ll happily do it with multiple separate midi and audio tracks, but I don’t want to overlook any ability of a vst external instrument track to have multiple lanes on different midi channels and such.
