Well, on Mac, we do have a stand-alone app, which at this point however doesn't export audio (which it may well be able to in a future update). So basically, yes, when porting to Windows, we'll definitely consider a standalone version, and anything we do will be 64-bit compatible unless the target format doesn't support that.
But a Windows standalone application may turn out to be trickier than a plug-in port, we're still investigating that sort of thing, so I can't really promise that just yet. ("tricky" as in "takes (too) long", not as in "how on earth should we do THAT?"
Another consideration WRT a stand-alone....while it appears feasible that we'd be able to make a Windows app that opens a file, processes it with PITCHMAP and exports the results, you'd be missing out on automation and the MIDI control of the plug-in. You can do a lot using the on-screen sliders (and in some regards, MORE than via MIDI), but the MIDI control really is a core feature. It is NOT likely that we'll be able to pack a full-on MIDI sequencer into a stand-alone app, or create a full DAW with MIDI *and* automation options (well, not at this point, anyway
). So it may be a good idea for you to look for a light-weight, fast-loading DAW app for your purposes regardless of whether we make a Windows standalone or not...
We'll probably not be able to reveal a Windows release date at the Messe, we haven't quite reached the point where we could give a reasonable guesstimate. Windows support is on top of our priority list, so we'll probably making fast progress once we get the new product out and return from the Messe.
