Synth is not in the bin, it's on the track.
Insert Soft Synth > VST2> Lounge Lizard EP-3 ('Simple Instrument Track' box checked)
FX Bin -Audio FX> VST2> TH2 Producer
VST2 (menu)> Enable Midi Input
Preferences> Wah Pedal = CC2 (Breath Controller)Add Wah (Crying)
No reaction from way to breath controler, but Lounge lizard plays. Wouldn't the fx in the bin use the same midi track that is playing the Lizard, as they are both on the same track?
