well, some days ago I had some contact to Steinberg and the Propellerheads. They told me VST 3.6 will be out at end of september (which year they didnīt say :-).. hi,hi..).
As I understand Rewire records directly into audio-tracks of VST and afterwards the VST effects can be applied.....
but I donīt have any more informations....
Letīs wait and looking forward to this miracle........
