For several months now, I’ve been involved with Rossum Electro-Music and have been testing their new eurorack module, the Control Forge. This is a programmable 8 stage control voltage generator that can be use in a variety of applications. It can act as a waveform generator or an LFO, an envelope generator, a step sequencer, and many other applications.

Dave Rossum is one of the founders of E-mu… yes that E-mu… and has created many important electronic instruments including the Emulator samplers and the SP1200 drum machine. The first E-mu instrument was a modular synthesizer system, and history comes full circle with Rossum’s new line of eurorack modules.

The 8 Stage envelopes are stored as “Presets”, and 500 Presets can be saved internally. Presets can be chained in a sequence, and this is where things get interesting. Structuring Preset envelope curves as rhythmic elements then sequencing these elements into a greater arrangement breaks away from repetitive loops in traditional step sequencers. The response is incredibly fast, so you can develop modulation textures when scaling up the time factor.

The following video is a handful of modules being driving by the CV out/ Inverted CV out and the two trigger outputs. The control forge knobs have been programmed to act in a variety of functions as the sequencer steps through different presets:
