Third-Generation Korg Workstation with OASYS Innovation! The M3 features a number of innovations distilled from the flagship OASYS including the new EDS (Enhanced Definition Synthesis) sound generator derived from the HD-1 engine design, the advanced second-generation KARMA functionality, and the multi-purpose control surface. Adding innovations such as the new concept of "virtualized hardware" that allows an even closer integration with DAW systems, Drum Tracks which provide a instant groove to play along with, and the new "Korg Komponent System" concept that facilitates more flexible system construction, the M3 music workstation/sampler opens a new and exciting page in music making - it's the workstation that rightfully deserves to wear the "M" that started it all. Korg M3-88 at a Glance: Four models available Enhanced Definition Synthesis: A new horizon of sound-making potential Effects Expanded Combination Mode Great sounds Second Generation KARMA Open Sampling Korg Komponent System Four models available The M3 music workstation/sampler is available as a lineup of four models: 61-key, 73-key, and weighted 88-key models, as well as the module-only M3-M. The 61-key and 73-key models use a proprietary new semi-weighted synth action keyboard developed by Korg for great playing feel and expressive aftertouch response. The 88-key model features the RH3 (Real Weighted Hammer Action 3) keyboard that reproduces the playing sensation of a grand piano, in which the low range has a heavier feel, with the touch becoming lighter as you play upward on the keyboard, allowing superb response to fine movements of your fingers. 40 pounds.
