Jim, I think the issue is... it is complicated to make something decent and more or less future proof. Meaning PG can update their HQ set, and solder it in. But then it would still be very basic as far as "tweaking" go. Even something simple as to change octave of a single instrument could be tricky.

If Peter G. recommended TT1 himself that was not a coincidence. Couple of years ago I reached out to Cakewalk developer asking for a possibility to change TT1 in some way to accept user SF2. I was told it is not possible because of licensing.

I have not found anything better than Halion (Sonic) as far as quality of sound, and a budget, but highly user flexible solution VSTsynthfont that would do GM program changes.

Bottom line, I think it would be hard for PG to reinvent the wheel. However, I think they could tweak HQ set, add instruments and make it work seamlessly with VSTsynthfont smile Or... have their own internal synth that can accept a user SF2 banks, that way users will not be "stuck" if they decide they do not like particular instrument.
