LV2 parameters not exposed to host

May be a JUCE bug

I am not convinced this is a plugin problem. Running in jalv the controls are available so maybe it is the interpretation of the plugin within Zynthian that is failing. Jalv can see the controls but Zynthian is not exposing them.

( @riban-bw Allow me to x-post your explanation here )

JALV only seems to allow control of control ports, not parameters via its CLI. JUCE presents controls as parameters. In JALV you see the names and (apparent) values of the parameters but attempts to set these fail. Direct numeric access controls the ports which are not displayed in jalv’s controls command. I think this is a flaw / limitation of jalv but means we can’t currently host JUCE LV2 plugins in Zynthian.
