Dan,
Thanks for making this video!
Cool that it works very similar to Toontrack, NI, Kontakt with BIAB.
You can try dragging Chord track to Tonalic right from header of Chord Track in mixer to the VST, skipping desktop. It might work.
If they introduce normal perpetual license(s) I will definitely consider.

Over last decade, I collected all NI Session guitars and bases, plus you lured me into toontrack world too. I am pretty much set for a long long time as far as guitars, bases, pianos and drums go, especially including annual PGM offerings however... When/if Tonalic introduce winds/brass I will most likely sign up for a month or two to get stems for some of my tunes.
