Mutable Instruments Edges

The first 3 channels are square/pulse digital oscillators, generated by subdivisions of a 4 MHz clock. 5 preset duty cycles settings are available from 50% to 95%. In addition, channel 4′s CV input can be used as a PWM CV for channels 1 to 3, with a 120° dephasing between each channel.

Channel 2 can be hardsynced to channel 1. Channel 2 and 3 are also equipped with a XOR ring-modulator, blending their harmonics with those of Channel 1.

The fourth channel uses a 12-bit DAC without oversampling/reconstruction filter to generate low-fi waveforms at a 48kHz sample rate. The available waveforms are sine, triangle, NES triangle, and various flavors of pitched LSFR noise.

• Optional semitone quantizer on the pitch CV input.
• Per-channel mini step sequencer (8 steps) – perfect for creating rapid fire arpeggios. When the sequencer is active, the GATE input works instead as a CLOCK input.
• Auto-calibrate feature digitally scaling the 1 V/Oct CV input to compensate for inaccuracies in CV converters… or to be used creatively to achieve other tunings than 1 V/Oct.

• Units manufactured before september 2015 require a 5V voltage source (for example Mutable Instruments Volts).
• All inputs: 100k impedance, DC to 2 kHz.
• Channel 1 to 3: 4MHz, 1-bit.
• Channel 4: 48kHz, 12-bit.
• Open-source hardware and firmware.
• 20-HP.
• Current consumption: +12V: 70mA ; -12V: 20mA.

DIY expander PCB.

• MIDI input; with MIDI mode switch (multitimbral: 1 channel per voice ; or polyphonic: 1 single channel with notes dispatched to the 4 voices) and MIDI channel learn switch.
• Sub-oscillator for channel 1 with NES-style stepped triangle waveform.
