Minimoog-like synth with vibrato depth controlled by mod wheel?

[tunagenes]

Here’s the basic flow you’d have to follow to get Surge working as you want:

Access Surge’s native GUI over VNC on Zynthian - you can find instructions in the wiki and lots times in this forum, but it is an ‘advanced function’ so let us know if you get stuck.

Set Portamento to taste, then right-click the Portamento control and enable Constant rate (if right-click is awkward over VNC, focus the control and press Shift+F10 — same menu). Add the mono mode and the mod-wheel->LFO->pitch vibrato while you’re there.

Save it as a user patch (.fxp) and drop it where Zynthian loads Surge patches. Loading it on the box then puts the whole state — constant-rate included — into Surge’s engine, even though the box knobs will still read zero. Sound right, knobs lying. That’s as good as Surge-on-Zynthian gets today.

I’m going to pursue an alternative using MiMi-d - which doesn’t currently support the constant rate glide you want, but I think could be made to and I think it’s builder-author @ricard would be interested.

edit - and here’s the post re MiMi-d:

Here’s post from another topic, MiMi-d related item at the end and of course there was some discussion before it in the topic-thread. Here’s the files that Claude made for me, I haven’t tried them out. Let me know if you’d like a Pull Request.
