“My final results from my Mutable Instruments Anushri build. Sound is all Anushri with a generous helping of reverb. Great kit, well engineered, fine for newbies like me. Get yours today, way fun.”
Anushri is a monosynth like no other. In addition to its analog VCO/VCF/VCA and digital modulation sources, it includes a fun and immediate note sequencer with step-by-step recording, and a gritty 8-bit drum machine with a truly original control interface.
Just like its elder sister the Shruthi, Anushri is not designed for industrial assembly but is instead sold as a kit – you can assemble it, modify it, expand it and service it without any specialized expensive equipment. Open source firmware and schematics give you full access, control and ownership of its circuitry and code.
Analog monosynth with sequencer and lo-fi drum machine
Analog synthesizer with primary VCO and secondary digital square oscillator
Saw-core VCO with temperature compensation and accurate tracking over 5 octaves.
Optional software-controlled tuning to increase stability and accuracy.
Sawtooth and square waveforms, with adjustable pulse-width and pulse-width modulation.
-1 or -2 octaves sub-oscillator.
Secondary digital square oscillator (2.5 MHz programmable interval timer) available as a linear FM source, a VCO sync signal, or an additional audio source sent to the mixer along with the VCO.
Mixer with external audio input.
12dB/octave multimode filter (LP/BP/HP), with sine-wave self-oscillation.
Post-filter overdrive/fuzz circuit.
Digitally controlled modulation sources
1 main ADSR routable to pitch, pulse-width, cutoff frequency. Segment time: 1ms to 12s.
1 simple 1-parameter envelope (morphing through various stages, including the shape of the main ADSR, and a rigid “GATE” style envelope) routed to VCA.
Velocity routed to either cutoff frequency of VCA gain (adjustable level).
1 LFO routable to pitch, pulse-width and cutoff frequency ; with 8 waveforms (triangle, square, ascending and descending ramps, S&H, bernouilli process, piecewise linear random process, noise). Frequency: 0.06 Hz to 100 Hz. Syncable to arpeggiator/sequencer clock.
1 triangle LFO for vibrato and/or growl controlled by the modulation wheel.
CV Resolution: 16-bit internal, 12-bit external, 2.45kHz refresh rate.
Arpeggiator and sequencer
Arpeggiator with 4 modes (up, down, up&down, random) ; 1 to 2 octaves ; 6 patterns and “acidity” setting adding accents/slides. Latch/hold mode.
SH-101-style note sequencer with step by step recording, up to 128 notes. Along with notes, rests, ties, glides and accents can be recorded.
Tempo set by internal clock (40-240 BPM) with shuffle, external MIDI clock or external 6/12/24 ppqn trigger.
Keyboard transposition of sequence during playback.
Algorithmic drum pattern generator using an innovative “pattern sculpting” approach. Drum patterns are “sculpted” with 5 knobs.
Drum sounds can be freely triggered from an external sequencer using MIDI channel 10.
x0x-style programming from a MIDI keyboard to override the algorithmic pattern generator.
Digital sound synthesis of analog-style BD / SD / HH sounds with tone control.
Audio resolution: 10 MHz, 1-bit (equivalent to 8-bit, 39kHz).
An upcoming Mutable Instruments product will use an array of these for its display. Love the vintage look! Just finished drawing all the characters today (some of the few special characters should give you hints…).
