we tried PdVst with Ableton and Audiomulch. Ableton doesn't recognize the PdVst plugins. I know that it doesn't work with VSTi plugins, but with "SYNTH = FALSE" it doesn't recognized, too. With Audiomulch it sound choppy, like samples are missing. Even a patch where only adc~ is connected to dac~ does not work. We tried it on Windows 98.
