I have downloaded Sample Tanks free Sonik Synth.
It appears to have installed correctly as it shows up as both an AU and VST
in the plug-ins window. I can drag it to the effects window and it shows up there. BUT I cant get any sound to output.
My M-Audio keyboard will trigger the built in Quicktime sounds properly. It also appears that the keyboard is triggering something in the Sonik Synth because when I hit the edit on the Effects window to bring up the Sonik Synth it comes up and striking a key on the M-Audio causes a visual response on the Sonik Synth window but no sound outputs.
