Ketron

The SD3 was one of Ketron's best-selling arranger modules and is still in great demand today among MIDI guitarists, accordionists, etc. The original Floppy Drive was abandoned by the standard version that now sports a door USB for use with pre-formatted USB sticks. That's enough download the free utility in your Windows computer for manage a 100 disk library on a single USB drive. The file system compatible with Microsoft Windows allows you to easily manage MIDI files, styles, recordings, etc.
