The MP-4 is either a 4 oscillator monosynth or a 4 voice polysynth. Packed with lots of cool features (cross modulation, oscillator sync, 2 LFOs, etc), this synth packs lots of power. Ghost Culture recorded a whole album with this keyboard - check out his track Giudecca, it's one of our faves, and made us realize we needed one of these in our studio too.
