The Forgotten Keys FK1 is a virtual Korg Mini-Pops MP-7 (AKA Univox SR-95) analogue drum machine. This was the drum machine used by Jean-Michel Jarre on his 1976 Oxygene album.
The FK1 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.
