Korg X5D
A 61-key digital synthesizer with 64-note polyphony and GM compatibility, built around a 16-bit AI synthesis engine.
Overview
The Korg X5D is a digital synthesizer released in the mid-1990s, with production noted in 1994 and referenced in materials from 1995. It features a 61-key keyboard and is built around Korg’s 16-bit AI synthesis engine, using 8MB of sampled waveforms.
