fitz is right on the money systems like pulsar-scope are based on dsp chips for processing,reason will not compare to host based processing no questions asked.,not saying reason is not good .What i am saying is this....
if u have ever used an access virus / korg ms2000 / nord 123 and modular /waldorf q/ microwave/
novation supernova/ u get the point these synths all run on dsp . the same dsp as in dsp card for comp ,the only difrence most synth run on multiple dsp chips u need a system like pulsar for that ...
if u want the ultimate computer workstation get protools ,each farmcard has multiple dsp chips for audio track-plugins, not the digi001 the (mix systems).
