Mutated: Yarns

Mutated: Yarns - A DIY Yarns PCB - a four channel MIDI to CV/Gate with bonus step and euclidean sequencers.

This is a PCB set in the Eurorack format.

Availability: In stock




Yarns is a MIDI interface offering up to 4 channels of CV/Gate conversion, and providing some of the MIDI message mangling features of Mutable Instruments' MIDIpal, including arpeggiator, euclidean sequencer, and a SH-101 inspired step sequencer.

Yarns provides 4 CV outputs and 4 Gate/trigger outputs, which can be assigned to up to 4 voices. In single voice mode, note, velocity, modulation and aftertouch (or other CC) CV are produced, along with a gate, a trigger, and a clock/reset output. In two voices mode, two channel of note, modulation or aftertouch CV are produced, along with two gates, and clock/reset outputs. Finally, in four voices mode, four pairs of CV/Gate outputs are provided.

The 2 and 4-voice modes are available both in a "polyphonic" and "multitimbral" flavour. The former receives chords from one single MIDI channel and dispatches them to the voices; while the later provides independent monophonic parts - which can be addressed to different MIDI channels, keyboard ranges, or even velocity levels. Various note priority modes (low, high, last) and polyphonic allocation schemes (voice-stealing, random, cyclic) allows you to fine-tune the CV/Gate conversion to your playing style. Each voice has a built-in digital LFO to interpret modulation wheel messages as a vibrato; can respond to pitch-bend messages; or can be smoothed with a glide/portamento control - no need for a dedicated module and patches to get the right response from a MIDI keyboard!

Each part can generate sequences either through an arpeggiator/euclidean sequencer combo; or with a SH-101 style sequencer with step-by-step recording, storing up to 64 notes. The module can sync to an external MIDI clock, and generate a clock/reset output at any subdivisions of the MIDI clock.

Other unique features include support for microtunings (either through standard MIDI message or from a selection of historical tunings or indian ragas), just intonation, and an "audio" mode which can transform one, two, or four of the CV outputs into simple digital oscillators.


NOTE:  All Mutated modules are designed by Olivier Gillet, and are CC-BY-SA.  

Ground rules:

  • Do NOT ask on the mutable forums or email Mutable Instruments for help.  There is literally ZERO support offered from those channels - don't be an ass.  A number of Facebook groups exist to help with DIY builds, and we're happy to help as well.
  • Do NOT (re)sell these, passing them off as factory modules.  Seriously - don't be an ass.
  • Do NOT be totally scared of SMT.  If you haven't done it before, it's off-putting, we get it - but give yourself a chance.  Learn something.  That's what (we think) DIY is all about.  We're keeping the prices on these low enough that you can afford to try and fail!
  • DO have a ton of fun building them, and use them to create awesome sounds.  Then go buy a Mutable Instruments module and SUPPORT Olivier's designs, directly.
