I should give Sonar 7.0 a looksee and get familiar w/ it. Years ago I read about an Intel / Cakewalk demo in Washington where Intel was trying to prove to the world ( AMD back then

) that they were 64bit fluent since AMD was first out of the gate.
My favorite Hammond afficiando Joey D. was demo'ng Sonar 64 and Project 5, but Cakewalk is way ahead in the 64bit arena, and w/ new MIDI and Rapture, which is the best analog emulated VSTi I have heard so far, it's quite tempting.
Personally I think Bowen's Solaris 5.0.8 BETA is the synth to beat, as every aspect of analog performance features like seperate Oscillator glide values and Unison stacking w/ SSM & Moog Filters make it a fierce Monophonic beast, very complimentary to my analog synths which I route into my Scope projects. But Rapture is the only VSTi I am aware of that also has these " old school " features, and selectable waves to boot. If that synth can harness multiple cores in a 64bit O.S. it could be an incredible experience.
Until then I will continue using Cubase 4.1 just to do drum tracks or provide tempo variants to VDAT as that's my little easy workflow solution, and if any of these apps. can get a better sound quality than VDAT, I will jump in w/ both feet. But my ears do not lie.
That's my simple high fidelity solution. Until I hear a better sound engine, I will stay with my 10 year old 32bit Integer recorder and playback device. With XITE-1 @ 96k playback, and the new 4.1 update from Creamware for Cubase, I'll have a way to re record my MIDI drum tracks and add vocals @ 96k and 5.1. That's what I am looking forward to.
4GB's more and Vista 64bit could really change things, and having an XITE-1 w/ such a capable sequencer and host is very tempting. I'll wait and see how VDAT works, but one thing is certain, VDAT loses it magical sound once outside of the Scope project, that is it's Achilles Heel IMHO.
Strength & Honor,
