MOD-UI pedal for SFZ input

Hi @jofemodo,

When running GenericFluidPlug-generated synths there is a problem with the Zynthian-UI. The sounds are not arranged in presets anymore but in values for a LV2 control port:

 [
        a lv2:InputPort, lv2:ControlPort ;
        lv2:index 4 ;
        lv2:symbol "program" ;
        lv2:name "Program" ;
        lv2:portProperty lv2:enumeration , lv2:integer ;
        lv2:default 0 ;
        lv2:minimum 0 ;
        lv2:maximum 83;
        lv2:scalePoint [
            rdfs:label "Classic Steinway" ;
            rdf:value 0 ;   
        ] , [
            rdfs:label "Studio Steinway" ;
            rdf:value 1 ;
...

This seems not to be recognized by Zynthian-UI so you cannot change the sound by encoder anymore. It seems also that Zynthian-UI hangs until you erase the pedalboard.

Do you have an idea how to fix this?
