 Find OASYS Technology in the Korg M3!
Many of the technological breakthroughs of the OASYS are now employed in the M3 series of workstations. Available in 61-, 76-, and 88-key versions, as well as a module, the M3 features the OASYS' 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.
Although the OASYS is no longer available, we've kept these pages online for reference purposes.

*1 Maximum polyphony depends on the kinds of synthesis engines and the number of effects being used.
*2 OASYS dynamically allocates voices to multiple synthesis engines when they are used simultaneously.
*3 The memory available for RAM samples will change based on the use of Expansion PCM libraries; the total RAM memory capacity will be increased in the near future with a system software upgrade.
* Sound processed with INFINITY.
* Specifications and features are subject to change without notice.
