Ok, got it - thanks!
I took your SF2 and created a FluigPlug-LV2-plugin: makes sound out-of-the-box.
Created a new pedalboard.
Changing sounds worked, Poweroff-Button not
Yes - seems to be a bug inside FluidPlug. The original FluidPlug does the same. Will try it on the MOD-Duo to see if this happens there also.
In Log when changing a program
DEBUG:root:WS >> param_set /graph/GenericFluidPlug_NiceTest program 0.000000
ERROR:root:Parameter Not Found: /graph/GenericFluidPlug_NiceTest/program => unorderable types: str() > int()
WARNING:root:zynthian_gui.zyncoder_read() => 'Classic Steinway'
This is weird, because I didn't copy the Classic Steinway sound.
My NiceMarkus.sf2 has it, but I removed the NiceMarkus plugin already...but didn't restart the zynthian box...which I do now.
Hmmm - yes, I know this problem. It is not a plugin problem but a problem of how the Zynthian-UI is handling the parameters of a plugin, see https://discourse.zynthian.org/t/mod-ui-pedal-for-sfz-input/543/18
Starting mod-ui on the zynthian-box.
Pedalboard is gone..didn't save it before.
Creating a new one. Same behaviour...don't know about the log messages yet..will save first..."NOTHING TO SAVE"
That's one of those "unstable" things. I saved a pedalboard before, but doesnt work now.
Do you have updated
mod-host before you send your log? I think this is not a plugin-problem but a problem inside MOD-UI. I am not using an external MIDI interface (or let's say: currently I am not using). Storing a pedalboards works also fine - but there were problems some time ago.
Can you update mod-ui/mod-host and confirm if this solves the MOD-UI problems?
I hope that the Zynthian-UI problems will be solved for the next release and I will look deeper into FluidPlug to solve the problem with enable/disable the plugin.
