Rossum Electro-Music Control Forge
Programmable 8-stage universal CV generator inspired by the E-mu Morpheus
22 HP Eurorack module
Control Forge is a deeply programmable CV generator descended from the E-mu Morpheus function generators, expanded into a supremely flexible Eurorack modulation source. At its core, it is an 8-segment function generator where each segment has programmable time (0.0001 to 9999 seconds), target voltage level (-5V to +5V), one of 67 transition shapes, optional randomness, and conditional jump logic. It can function as an envelope generator, LFO, step sequencer, complex function generator, quantizer, and even an audio-rate wavetable oscillator. With 500 saveable presets, 200 preset sequences, AutoChain for multi-preset patterns, and two programmable trigger outputs, it is one of the most versatile CV sources available in Eurorack.
Features
- 8-segment programmable function generator with variable time and level per segment
- 67 transition shapes including linear, exponential, circle, chaos, zigzag, and CV passthrough
- Four Level Modes: Absolute, Absolute Quantized, Relative, and Relative Quantized
- 16 conditional jump modes testing gate, logic, and CV inputs for dynamic contour branching
- Three independent randomization sources with linear or gaussian distribution
- 500 saveable presets with alphanumeric naming via segment buttons
- 200 preset sequences (up to 20,000 steps) with Pause, Halt, and Bumper commands
- AutoChain links consecutive presets for multi-preset LFO or envelope patterns
- Two independently programmable trigger outputs with selectable width (48us to 100%)
- Real-time Time Scale control via encoder (0.031x to 32x) multiplied by Time Scale CV input
- Real-time Quantize and Randomize with latch-on via encoder press
- Audio-rate operation for use as a wavetable audio source
