I have figured this out in VCV Rack. Audio amplitude is controlling the level of pan and transients are triggering an inverter, thus changing the left/right direction. Cool effect, now that I've heard it, I think I have a song I'll use it on.
To adjust the
- level of pan = CV on the mixer
- threshold of transients that trigger the flip = threshold
- how fast the flip happens = rise/fall
All done in free modules. DM me and I'll send you the patch if you like.
