It's an emulator of the
1. Polysix - polyphonic 6 voice analog
2. MS20 - Portable modular
3. Wavestation - Vector synth
4. FX - compressor, limiter, overdrive, equalizer, talking modulator, flanger, phaser, chorus, delay, reverb, etc
5. Legacy Cell - Combines all of the above in numerous amounts in a single patch ( thaz pwitty sick ).
with this set comes a midicontroller that looks exactly ( 84% of original size ) like the ms20 itself including the patchrouting.

it lacks a dsp chip, there's also no ide card anything and the ms controller is merely a bunch of knobs. This means that a low latency audiocard is required and a fast cpu/frontbus, talking at least 1,6 gHz.
Considering the issue above, i can think of a pretty nasty combo with the Korg Microcontrol. The gui of the Legacy kit has a controller embedded based on the Microcontrol to tweak all of synths, besides the ms20 obviously.
Combine this with the Emulator X farmcard to support the lot with the dsp power and use the drumpads on the microkontrol to work with a mpc ( but sounding like a sp1200, emulator or whatever emu sampler ) feel to it and with no latency.
That's a nasty cheap little daw! Definitly a hiphop producer setup and beats the costs of even the mpc1k.
