If I got you right… check in the Track DSP tab, in the bottom left corner where u see the list of native DSP effects… by browsing down you see another “dir” named Meta Devices. Among those Meta Devices you find *vstiAutomateDevice… that’s a device that allows you to take control of any VSTi parameter via Automation envelopes…
I think modmaker is looking for a way to edit VSTfx parameters in the same way as VSTi params, in the effect column of a track. Strange, I guess I never noticed you couldn’t! Envelopes are just so much nicer…
As far as I know (not far) there’s no way to translate between envelopes and in-track values. Sure would be nice.
