Space Station Pro will continue to perform in a live situation after total Hard disk failure, which is not as rare as you may think. When running the SS Pro in win 98 or 95, it will continue to respond even after a VXD error and windows is no longer around to Alt Tab to.
If true performance is what you want then the SS Pro is the sampler for you. Waves of different frequencies can be played back together without any pitch changes. The Output frequency can be changed in Realtime without the waves slowing down or speeding up. When changing the Output frequency to a lower setting the polyphony is immediately doubled without changing the qaulity of any loaded waves. Waves in memory can be played back from a sequencer, MIDI keyboard, Mouse or the qwerty keyboard, with MIDI control, and recorded as another wave. 16 Pro instruments can be played back simultaneously using external devices, or buy a sequencer on the same PC with the use of a second MIDI or sound card.
The SS Pro has a full MIDI spec that matches the most expensive Keyboards and samplers on the market. Waves and instruments can be loaded as you playback and can be played even before they finish loading. MIDI data can be transmitted using the fixed and user mixers.
