B Rock collection RP-1.64 seems to have the most presets in.
Oh, that's an old one. No doubt it's full of experimental presets. There are more presets using the newer Rapture features in something like
00 Relative 110, but you'll need to have the (free)
Rapture Expansion Packs 1 and 2 installed [available from Cakewalk to registered users].
The thought at the time was that most every Rapture user would take advantage of the Cakewalk freebies, and those packs added a number of new wavetables & multisamples. Other than that requirement, the .progs were all designed to use what was in a "standard" Rapture installation (an updated synth, plus the two free Expansion Packs).
Anything that required custom multisamples for the presets usually had an installer courtesy of Chad Beckwith. Scook mentioned the exception - Architecture TB-32. In case you went to the direct download page in PatchArena, I linked the Synth Resources page above (it has some brief descriptions on requirements). Sometimes, I added a ReadMe .txt file or Quick Start .pdf to the zipped archive.
Regretfully, there is no 'one size fits all' method that will apply to everything here. These sets go back 8-9 years, and I was adapting my approach & learning new tricks as I went. The refinements culminated in U-120 with that ongoing FiSound partnership. It's always better to have a few sets of eyes & ears trained on any ambitious project.
