No idea if this is helpful. After rebooting, reloading the snapshot and manually changing the delay time to tempo sync - the delay can be synced and reacts to tempo changes. So basically the plugin should work.
@baconpaul is MPE enable exposed in the LV2 as a parameter? If not, could it be? I have observed that the factory presets do not change the MPE state but user presets (saved in zynthian) do. An example of an improvement would be to put the A & B effects into “A FX” & “B FX” groups, rather than in “Global & FX”.
The ordering of parameters is suboptimal in zynthian, e.g. "Global & FX#1 contains:
- Character
- FX A4 Param 1
- FX A4 Param 2
- FX A4 Param 11
The grouping of parameters could be slightly improved. Was that done by @baconpaul or by us? similarly, the values are not well formed, e.g. enums are not implemented and ranges are not shown appropriately.
The massive quantity of parameters exposed in zynthian is rather unwieldy and I doubt anyone is likely to use this for sound design. It may be more useful for mapping MIDI CC to some parameters. Maybe zynthian could/should be modified to allow controls to be hidden so that users can chose what they see, maybe with some profiles for common controls, e.g. envelopes. BTW, envelopes are not presented with the zynthian envelope editor… but that may be challenging.
