Since the thread itself requests input and since I happen to be passing by, I want to offer that I also use the DAW by Zynewave called Podium. Full multicore support and available in either 64 and 32-bit versions for Windows only (sorry, no MAC nor will there be), I have probably used S-Gear more with this DAW both recording and extensive playing, than my other main, REAPER.
So, I'm writing in today just to state for the record that S-Gear performs and records flawlessly on Podium, both 32 and 64. After I introduced S-Gear on the Zynewave Forums, at least two colleague friends have also snapped up a licensed version. It's working perfectly for them as well, since any issue would have been posted first on that forum immediately if not. Currently, Podium on a very very slow update cycle, since Frits (Zynewave) is extremely busy porting the DAW to a tablet version. It is safe to assume for now that no further updates will cause any unforeseen issues.
Therefore, I believe it is safe to include Podium as another DAW for Windows that works with S-Gear. Should this change, I will notify.
Windows (VST): Zynewave Podium all recent builds to current 3.2.1
Cheers!
