Stereo LFOs #5838

Is your feature request related to a problem? Please describe. It would be great to have "stereo phase" on the LFOS.

UVI SHADE has that implemented really nicely ( they called it "SPREAD" ) where you can make an LFO "stereo".

For instance you can assign an LFO to CUTOFF and then play with the "STEREO SPREAD" of the LFO which basically would ( as you guessed ) shift the PHASE of the modulation between LEFT and RIGHT side of the filter.

At 180 phase when a triangle would be going up for the right side on the cut-off it would be going down on the left side.

this is a really powerful and easy way of making stereo sounds.

This example is similar to how the PHASE knob works on Ableton's Auto Filter as well.

Modulation in Surge is strictly mono, this would probably be a pretty big overhaul of the innards. I suggest using Vital for this sort of stuff, instead, since it's made exactly with this sort of stuff in mind. 🙂

Yeah i was more enamored of this one. I'd like to keep it open as a speculative issue. With vector valued modulators which we just added it is way more tractable than with the 19 code base.

The trick would be to have stereo-modulatable parameters. cutoff and resonance would be one such param. some of the fx ones would also i bet. So will tag it currently unscheduled but will ponder
