VSTPlugin.ar Omnisphere

hey,
Im trying to get Omnisphere running with the VST Plugin and not quite sure how its done.

 (
SynthDef(\insert, { 
	arg bus;
	var sig;
	sig = In.ar(bus, 2);
	sig = VSTPlugin.ar(sig, 2);
    ReplaceOut.ar(bus, sig);
}).add;
)

    ~fx = VSTPluginController(Synth(\insert,[\bus, 0])).open("C:/Program Files/VSTPlugins/Omnisphere.dll");

    ~fx.gui;

when i use the GUI there are no Parameters available.
I also tried another VST: Spitfire Audio LABS Choir. I have Parameters in the GUI but dont know how to use a Pbind to sequence the instrument.

(
SynthDef(\insert, { 
	arg bus;
	var sig;
	sig = In.ar(bus, 2);
	sig = VSTPlugin.ar(sig, 2);
    ReplaceOut.ar(bus, sig);
}).add;
)

~fx = VSTPluginController(Synth(\insert,[\bus, 0])).open("C:/Program Files/Steinberg/VSTPlugins/LABS (64 Bit).dll");

~fx.browse;
~fx.gui;

(
Pbind(
    \type, \vst_set,
    \vst, ~fx,
	\midinote, 60,
    \dur, Prand([0.25, 0.5, 1], inf)
).play;
)

any suggestions? thanks :slight_smile:
