Le Lotus Bleu releases free Korg Legacy MS-20 and Polysix sound banks
The Polysix bank contains 20 patches, while the MS-20 bank has 24 patches.
You can use these patches in the Polysix / MS-20, or use them as basis and inspiration to build your own presets in the Legacy Cell, to get the benefit of integrated MDE-X effects, automation possibilities, or make layers with a MS-20 or another Polysix.
A commercial sound bank for the MS-20 called PickCell One (more than 128 presets atm) will be released in the near future.
Visit Le Lotus Bleu for more information and links to download the free sound banks.
