I was also focused on the instruments section and not the effects. I'm running Windows 10 64 bit but am using a 32bit DAW so am also using Cabbage32. I'm getting the same error when trying pvsAdsyn & pvsCross. In the editor view, I see that it can't find "osc.dll". However, I do see that file in the installation (though I'm not sure why it is necessary). The Adsyn GUI displays in Cabbage but there is no sound. I can export a VST but there is not sound in the DAW when I run a synth through the input. I've attached two screenshots. In case it is relevant, I had Cabbage64 installed until recently and uninstalled because I couldn't use the output VSTs. Also, once properly generated--should pvsCross have two audio inputs?
