Another rarity from the halls of EMEAPP, here we have the ultra-rare RSF Blackbox from the late 70s. While it doesn't look like much on the outside, it is capable of a pretty amazing task: it can turn a monosynth into a polysynth by using it's CV/gate output. Intended as a peripheral device for the RSF Kobol monosynth, the Blackbox is compatible with a plethora of other vintage monosynths. In this video, electronic music pioneer Don Slepian will demonstrate the Blackbox's capabilities as a stand-alone instrument.
