The Shruti Module

The Shruti Module by experimentalsynth
"A quick sketch using a MakeNoise Rene' to modulate a bunch of non-modular synths and effects. Moog CP-251 is supplying the master clock. Rene' is modulating multiple parameters on a Moog Voyager (filter cutoff & osc 2 freq), filter cutoff on a Moog Little Phatty and osc freq on a MF-102 ringmod. The CP-251 LFO is also modulating the filter cutoff of three MF-101 low pass filters processing a Yamaha MO8 (in stereo) and a Korg MicroX."

"Teaser of a work in progress "mods" for my Shruti-1 from Mutable Instruments. No hack, no mods, no engienering, just an assembly of a scavenrenged Edirol PCRA30, some wemgé wood piece and my beloved Shruti-1 the one! Now it's time to design the faceplate and finish the wood working :)"

Shruthi-1 Filter Modulation

YouTube via e7ektro | February 19, 2011 |

"The Cutoff Frequency of the filter (SMR-4) is modulated by an LFO with S+H shape. The resonance is at maximum level. Cool effect I think. The Shruthi-1 has an interesting modulation matrix."

Shruthi-1

YouTube via e7ektro | February 07, 2011 |

"The Shruthi-1 from Paris/France based Mutable instruments is a nice hybrid monophonic synth with digital oscillators and an analog filter which can be selected among different flavors. The kit comes with an OTA-based filter which is built with widely available ICs. The digital oscillators are generated on an 8-bit microcontroller. Apart from the usual analog waveforms it can do wavetable synthesis and Phase Distortion synthesis among others. The user interface is really simple and intuitive. See mutable-instruments.net for further information."

"this is an accelerometer chip in a ball that controls an rgb led and also outputs control voltages to a fantastic little synth called the shruti-1 (available as a kit).
I've also added a softpot which is controlling the mix between vco1 and vco2."

Mutable Klee Software Sequencer V2

YouTube via dnigrin | November 24, 2010 | 2 likes, 0 dislikes

"Software Klee Sequencer, version 2, controlling two Mutable Instruments synthesizers: on the left a Shruti-1 in a custom enclosure, and on the right, a Shruthi-1. No external processing or other synths - all sounds from the Shrut(h)i's, and all MIDI signals generated by the Software Klee.

More info:
Software Klee Sequencer: http://defectiverecords.com/klee
Mutable Instruments: http://mutable-instruments.net"


"what is it:
a MIDI-enabled software recreation of the electro-music.com hardware Klee step sequencer - developed with the input of the sequencer's creators! Now with even more functionality in version 2!!
what are its features:
Includes virtually all major functions from the hardware Klee, and adds many new ones. New features in version 2 = new

• VST instrument hosting new
• Intelligently constrain output notes to scale (using Modal Object Library) new
• Output chord based on active root note - up to 6 notes in chord, plus root note new
• External pattern load via MIDI or audio input triggers new
• External MIDI controllers support via MIDI CC messages, with MIDI learn new
• Group A - Group B output new
• Convert active LEDs to active switches, for Groups A, B, or A and B new
• Reverse sequence direction new
• Built-in clock divide capability, now with additional options new
• MIDI output to any hardware or software synths
• Internal or MIDI clock control
• 10 preset slots for instant recall of parameters
• Presets can be saved to and loaded from disk
• Synchronous load - loading of pattern happens on clock pulses, and not in between
• Load on Play feature to allow for loading of pattern each time clock started
• MIDI-controllable baseline note
• Custom definable note range allows for alternative scales"

Just messing with me newly built Shruthi-1

Mutable Instruments Shruti-1 with SM4 filter Assembled

via this auction

"What is it?
The Shruthi-1 is a hybrid digital/analog monosynth. Its hardware design is deceptively simple, but the sonic range is wide: sometimes grungily digital like a PPG-Wave, fat and funky like a SH-101, videogame-y like a Commodore 64, weird and warm like an ESQ-1 ; but more often than not, truly original.

Best of both worlds
Digital…
An 8-bit microcontroller plays the role of the two main oscillators + sub-oscillator. This allows the generation of (aliasing-free) classic analog waveforms, but also wavetable/transwave synthesis and a trove of weird digital algorithms (sinewave bitcrushing, formant synthesis, phase distortion, bit toggling, XOR modulation).

... and Analog

Beyond this point, everything is analog. Most of the Shruthi-1s are built with the SMR-4 filter, a warm 4-poles “modern analogue” low-pass (no vintage IC). But you are in no way limited to this! The filter section of the Shruthi is on its own board and can be easily replaced. We currently offer 2 alternatives filter boards, one with the CEM3379 VCF/VCA chip of the Ensoniq/Waldorf fame ; and one with the classic SSM2044 VCF. More to come, based on vintage chips or modern OTAs and VCAs! From silky-smooth to squelchy or fat: pick the filter that matches your personal taste best.

The Shruthi-1 has an audio input: external signals can be processed by its analog section, under the control of the digital LFOs, sequencer and arpeggiator for crazy gating and re-enveloping effects. A perfect way of warming up the sound of your favorite VA or… cheesy organ!

Before all, a musical instrument

Designed as a tool, not a toy

Getting a microcontroller to make bleeps and bloops is easy, but this is not where we wanted to go. We took the challenge of creating an instrument that could play in the same league as a Waldorf, Ensoniq or DSI synth; and from what Shruthi-1 users can attest, we have succeeded. Gameboys and Prophet-VS’ both ran on 8-bit cores. Guess what inspired us…

Of course, you are free to use the “dirty PWM” or “8-bits” oscillators algorithms if nasty bleeps are what you are looking for!

Feature-packed

We have packed the Shruthi-1 firmware with plenty of great features: a complete MIDI implementation (large CC coverage, NRPNs, SysEx data dump including wavetable transfer), a 12-slots modulation matrix, a 16-steps notes/CC sequencer and advanced arpeggiator with some unusual time warping modes, and even a polychaining feature to turn several Shruthi-1s into a monster polysynth!

Hackable

Open…

The Shruthi-1 firmware is GPL. Schematics are released under a CC license which gives you the freedom to build your own synth. We also provide assembly instructions, BOMs with references, case drawings, and some analyses of the filter circuits.

... and low barrier to entry

Posting code and schematics is not all… The Shruthi-1 has other great assets that make it a cool hacking platform:

A readable, well-structured code-base in C++, relying on a freely available toolchain.
Schematics editable with the freeware version of Eagle.
An easy firmware update procedure: just press a button and play a midifile to upgrade your Shruthi.
Solid foundation for developing your own analog filters, modulations and effects circuits. We provide PCB templates and an experimentation board to get you started on the design of the next Shruthi-1 filter board!
So get ready for new filter boards or hardware extensions!

This is from the second batch of Shruti-1's that went on sale the other week. It was hand assembled and tested by geargasstore in our shop. It comes with the clear acrylic case with honeycomb patterns on the sides."
