Cygnus X-1

An analog/digital hybrid monosynth built in July 2010.





Oscillators:
Two digital oscillators, each can select from 24 waveforms.
The oscillators can be combined using one of the eight mix modes: add, subtract, IOR, XOR, split, switch, FM, phase distortion.

Wave Shaping:
Further digital processing can be applied using one of the wave shaping options: phaser, pitch doubler, sync, xor ring, FM 1, FM 2, resonance, wavefolder 1, wavefolder 2, phase distortion 1 & 2.

Modulation:
There are three LFOs and two envelope generators which can be routed to any of the main synthesis blocks, and a dedicated LFO for the joystick controller.

Filters:
Two analogue filters in parallel -
Filter 1 is a 24db/oct low pass SSM2044
Filter 2 is a 24db/oct switched capacitor MF10 with LFP, HPF and BPF modes.

Sequencer:
Sequences of up to 256 steps can be stored using the step-programmable sequencer.
