Edirol Orchestral or Reason will have the sound you are looking for. The ones in Dr. Dre's song WERE from a triton. It's a preset I beleive "sectional strings" or "string sectional"or something to that effect(can't remember the exact name). That's fact whether you beleive it or not. I've heard it replayed to the exact key a million times. Once again people choose to render this, compress that, eq those, and end up with something not even close rather than digging up the preset.
Out of the 800 video tutorials you've ever watched have you ever seen anyone compress anything? Tweak anything? Or do they just skip thru presets until they find one?
