Ebay Description:

The Korg X3R is a pressure and velocity sensitive 2U rack (8 channel multitimbral) single (32 voice) or dual (16 voice) oscillator synthesizer, featuring 340 waveforms and 164 drums (16 bit, 3MW, more via card), dedicated filter and dual pitch LFOs, dual stereo effects processors (47 effects), stereo and dual individual outputs, and MIDI. Each oscillator channel features a resonant low pass filter and dedicated (pitch, filter, amplifier) 3-stage envelopes. The 200 user editable presets can be saved via MIDI SysEx or memory card (also has 136 GM presets).
