Good news! I’ve just implemented “LV2 Port Groups”, a LV2 extension that allows to group the controllers and other ports in a convenient way.
It’s not very extended yet, so there is only a few plugins that currently have groups defined. You can try with the V1 series:
Probably there are more plugins, so please, send feedback if you find more.
Anyway, we can add the “group info” to the plugins we want. Currently it must be done by hand, but we could develop a more friendly interface if convenient.
For testing this feature, please change your zynthian-ui branch to “ctrl_group” and update.
