Black Coffee System

The black coffee system incorporates everything you would expect to find in a small monosynth and a whole lot more. Considering this is probably the smallest monosynth in the world you will be please to see very little has been omitted. Through the clever use of routing through 12 switches and 12 pots, an extreme wide variety of sounds can be produced.

Unlike many other analogue minisynths, ours includes MIDI. MIDI allows you to play the black coffee from a MIDI keyboard or sequencer. MIDI channel can be selected and you get control of pitch, gate (note on/off), filter cut-off control (via MIDI controller 1/mod wheel), TB303 style `Slide' on/off (activated by overlapping notes) and Accent on/off (a velocity of over 64 will briefly increase the filter cut-off).

There are three parts to this system: the actual black coffee module, the case, and the MIDI to CV converter (MCV). All 3 parts together are called the black coffee system. Parts can be bought separately to allow choice of units you need for your requirement.

The black coffee module will fit into a Concussor, Integrator and A100 modular system rack so can be integrated and used with a modular synth system. By switching the VCA to `THRU' the unit can then be used as a versatile analogue effects unit for guitarist and vocalists. With 12 sockets, 10 controls & 12 switches you won't be short on creativity.
