What is korg oasis?

As an AI language model, my training data only goes up to 2021 and I'm not aware of Korg Oasis existing as a product name. However, I can offer some information about the well-known Korg OASYS synthesizer/workstation:

Korg OASYS, pronounced "OH-a-sys", is a professional-grade hardware synthesizer and workstation released in 2005. It has since been discontinued and succeeded by the Korg Kronos.

The OASYS features a large touch-screen interface, advanced synthesis capabilities, massive sound libraries, and flexible audio/MIDI recording and sequencing capabilities.

It uses HD recording and software synthesis to produce dynamic, realistic soundscapes. It also has a high-capacity internal hard drive, allowing users to store and access large amounts of audio and MIDI data.

While it is no longer being produced, the Korg OASYS is still considered by many to be a classic and highly prized piece of music technology.
