preset changes for AU and VST instruments on OSX via program changes

[lokkiikkol]

program changes do not change presets on the synths i tried.

AU: Vital and Helm
VST: Vital and Helm

Helm does actually show a preset dropdown in the rack view, but if i send program changes to it nothing happens. do i need to specify a specific midi channel? i.e. 1?

It seems that both plugins don't support Program Changes.
mtytel/helm#175

If a plugin support PC messages, I think it should work in Carla.

Ok. Is there any other way via savestate in Carla? I thought the whole point of the "Map Program Changes" Setting was to allow preset changes on plugins that don't support program changes.

actually, on the link you sent it states that program changes do indeed work on helm but need additional bank messages to be sent as well...

In the Edit window, set the midi filter "map program changes". I've just test that on Helm vst. It works for me (linux)

you are right! i got it to work on helm too, thanks!! so it seems to be a vital problem.
