SourceBuffer/VST synths Not working Beta27.1 win7

I’ve can’t seem to get source buffer to work in beta27/win7, also vst synths don’t seem to work for me either. I’ve replaced the source buffer in the vst help patches from here ((vst)) with audio in, but still no sound. Any ideas?

i tried the waveplayer with some random audio file playing in loop as source and it worked. i don’t have the patch saved, though.

Waveplayer works fine here too…
Audio in and source buffer dont make the vst work however.
Source buffer doesn’t work at all though, which is a shame as I’ve only just started using it!

I recall a thread where the conclusion was that sourcebuffer needed some rework.
