I created my first LV2 plugin. It’s a switch box that allows for choosing either 1 of 4 outputs, much like MOD’s SwitchTrigger4, but with the advantage that the current selected output is stored in snapshots. Since I don’t own a MOD device, feel free to shoot a PR with the built files for MOD.
Weird. I’ve always been using switchtrigger4 with snapshots. Snapshots actually just store the current state of lv2 ports for every plugin on a pedalboard in a json file, there are no reason I can see why a plugin would not have its state written in the snapshot file, unless it is explicitly excluded from snapshots with a modified version of mod UI or another tweak.
