Hi there,
Does anyone still use Cakewalk Pro Audio 6? If so, will this version work with a VST such as Miroslv Philharmonik. If not, is there an interface that will connect the Pro Audio 6 with the Miroslav.
 
Thanks.

I'm not sure but I think PA9 was the first version to include DX support and no version of ProAudio ever supported VSTs.  At one time there was a Cakewalk wrapper that allowed PA9 to run VSTs but never VSTi.
I don't think the wrapper is even available from Cakewalk any more.  Google might help you find a 3rd party wrapper for a VST but I'd be surprised if you find something to work with PA6.  It's really, really old.
