I suspect I will add polyphonic versions of some of my modules alongside the existing modules where they currently have multiple instances (6 gates for example).
I don’t think many of my modules would benefit from a direct replacement, because normalling could not work the same for many of them. So polyphonic versions would most likely be in addition to the existing versions.
I think they’re going to create some headaches and complications, mostly around being able to visibly tell what cables are carrying multiple channels or not and knowing when ports expect them. Also probably a need for general adapter modules.
On the plus side, I think they are probably a boon for utility cables. Carrying ambisonic XYZW around a mixing board, data from chainable modules, stuff that isn’t “musically interesting” and just needs to be shuffled somewhere else. As much as I don’t really care about having to wire up L and R channels, I really would not want to have to keep wiring up multi-channel surround sound.
FYI, Grayscale and I are working on a polyphonic utilities plugin for VCV so that third-party plugin developers don’t have to make a bunch of simple utilities for polyphony to be useful. Might be ready when Rack 1.0 releases.
