The Forgotten Keys FK2 is a virtual Maestro Rhythm King MRK-1/MRK-2 analogue drum machine. Most notably used by Sly Stone as well as George McCrae on his 1974 hit: Rock You Baby.
The FK2 features isolated multi-samples of each drum sound and re-creations of all the internal rhythm patterns. These patterns can be combined with each other just like the original. The volume, panning, tuning and mute status of each sound can be adjusted, and the MIDI input and audio output routing can be customised.
