2500+ Waveforms at the [Cakewalk] Store

First, the disclaimer: I'm not employed by [Cakewalk] or Galbanum. I bought the license to this wavetable set. For myself, there's no money to be made from it. That is, unless you consider the work that it's saved me with constructing my own similar wavetables in an audio editor. At little more than a penny a piece, yeah ... I 'made money' on that deal.
Are they that good? Yes, but don't take my word for it. Check out the detailed material on the Resources page. If you really want to know what I personally think about this set, read my review here. And I don't write reviews.

This should be obvious, but this set will work in any flavor of Dimension, Rapture, z3ta+, or anything else that supports the .wav format. I can't speak directly for Mac users, but there's clear indications of compatibilty there as well.
