Maybe somemore background on my workflow.
I send a lot of time creating textures/sequences in AudioMulch and Bidule after which they get assembled and multitracked in Ableton Live . So this is pretty much all audio we're speaking here . Not so much midi sequencing à la Cubase etc. . I have always been an audio kinda artist that's how come ...
Now with the advent of Live 4.XX we have the midi sequencing possibility .
Unfortunately good vsti's often equal high horsepower PC's and the faster the cpu's the higher the demands raise on the system for latest cry good vsti's (and in fact vsts as well) ... and that's a kind of trap i'd Like to avoid in som way by using dedicated dsp's.
I like to think that by offloading the kind of synth/sampler to the dedicated dspboard ), I'll make better and longer use of the PC CPU for other tasks/applications. And that's why I'm eyeing the Luna in this setup : in order to use the STS sampler or Modular III , sequenced by Live3 but keeping the PC CPU as much as possible for Live and leaving the synth/sampler side to the Luna DSP.
Same thing on the mixdown/mastering side where I'm looking at the mixtreme : here the DSP can take care of the power needed to have excellent mastering efx where the equalperforming plugins on a PC will tax the CPU accordingly and hitting the cpuceiling much faster of possibilities of the application(s) i'm using.
If I had the money available I'd probably go straight for The Scope Project or Professional , but i have to balance the checkbook and that's why I was thinking about doing it in this -creative- way ....
Basically I would have :
main application ableton playing audio files and midi files , where the midi files would power eg. the Modular III and where all the output would be routed into the Mixtreme for final mixdown ...
