Hmm! saw that on the KVR site. I'll have to look into it. Thanks Oz.
KVR site eh ... and Audition people aren't interested in soft-synths
to question whether Audition is the best interface to implement softsynths hardly precludes interest or use of them
until v2 AA was not a robust real time multitrack performance app, but integrating data 'rendered' by other engines was pretty easy. earlier versions of CE/AA had small enough CPU footprints that once MME driver issues were resolved a number of audio apps could reside actively, harmoniously (in ways I found more problematic with Cuebase &/or cakewalk product)
& a number of softsynth rendering engines permitted 'capture' with 32bit dynamics, something most 'real time' audio apps still can't accomplish
additionally CE/AA has been around significantly longer then it has been genuinely cost effective for an 'average' project studio to integrate multitrack recording & real-time softsynth on the same physical machine . . . side stepping the issue of sample playback, by the time you employ a patch with a handful of modulations coupled to performance dynamics, with dynamic harmonic feedback control, full reverb CPU load seems puny (in comparison) (plus there are latency issues coupled to the physics of sound not merely CPU/HD seek time speeds) . . . while you can buy specialized DSP boards to offset the load those still tend to redshift a system in direction of $10k very rapidly
it is possible that average DAW specs are now robust enough to support, within AA something like Steve's suggestion . . . but to have cobbled something on to AA that was by default crippled (more or less the ProTools approach to reality) I still think would have been self defeating (PT was marketing, not software, success). . . a trick in writing any code is to make it powerful enough to 'do' something right now while building in flexibility to deal with cost of Moore's Law . .. and that's not an easy task . . . there's a mountain of good code that failed to survive a succeeding cycle of hardware enhancements
I'm not an adobe fan (from photoshop/quark days), haven't upgraded to V2, don't use AA for tracking, yet core resiliency of CE code has kept AA a very active element of my daily arsenal . . . doesn't mean that AA does not need to evolve, merely that prior to V2 AA/CE was pretty much a crown species of audio editors and while I use synthesis extensively, MIDI quite frequently I do not disagree with contention that additional MIDI capability would quite probably have been crippling rather then enhancing for the app.
what happens from here is a different story
