Question for mutable yarns users

I’ve decided to step into the eurorack/modular world and want to integrate it into my current setup, thus I need a midi to cv converter. the mutable instruments yarns, after constant research the past few hours, seems to be the one holding my attention.

my question is can I use the midi out on the yarns to arpeggiate my moog sirin (or even a track on my digitakt) via the external devices midi in? could I use the midi out on the yarns to send anything else interesting to my sirin or digitakt aside from clock?

If i understood the Manual correctly, it IS possible to Midi in/Out from Digitakt into Sirin.
Not sure If it does CV to Midi, besides Note/Gate.

I think my inexperience in this area is giving me difficulty articulating myself. I believe what I’m trying to get at is if I could send CV chord info from a separate module to yarns and for yarns to convert that CV signal to its midi out which I could send to sirin in the form of arpeggiation.

also if yarns, through any means with or without the use of other modules, could send midi out to an external synth for any meaningful or interesting purpose aside from clock. sorry to be so vague and difficult in my wording, I’m just curious as to why yarns has a midi out where most other modules in its category only have midi in.

>> (OUTPUT MIDI MODE) : MIDI output routing. When set to OFF, none of the events received by this part are forwarded to the MIDI out. When set to THRU, all events received by this part are forwarded to the MIDI out without any processing. Finally, when set to AR(P/SEQ), all the notes generated by this part’s arpeggiator/sequencer are sent to the MIDI OUT.

Thats all for Midi Out.

check this out :heart::heart::heart:

I’ve been working on this on and off for a few years, and am excited to release it to the public! I hope people enjoy using it. Pasting from the README:


  • Enhance Yarns as a tool for solo and collaborative musical composition
  • Obtain maximal functionality from a minimal MIDI controller
  • Expand Yarns’ abilities as a digital synthesis voice


  • New layouts, including a layout that features a 3-voice paraphonic part with internal envelopes
  • Looper with real-time recording
  • Global control and display of the active part and its play mode
  • Oscillator PWM
  • Velocity filtering
  • More control over vibrato, input octave, sustain behavior, and sequencer/keyboard interaction
  • Sequencer-driven arpeggiator
  • Check the changelog for more!


  • Installation of this firmware is at your own risk
  • Presets saved in this firmware cannot be loaded with the manufacturer’s firmware, and vice versa
  • Some changes are not documented in the changelog
  • Some of Yarns’ stock capabilities have been downgraded to accomodate new features (e.g. the sequencer holds 16 notes instead of the original 64)


  1. Download yarns.syx from the latest release’s assets
  2. Follow the manufacturer’s instructions for installing new firmware

and this from 2.20 but he’s released 2.30 last Friday and it’s Bonkers!!! :heart:

This release aims to give Loom users deep and flexible control of timbre and amplitude dynamics.

Full details are in the manual! Please note that this release’s preset storage format is not compatible with previous releases.

New features

  • Braids-inspired oscillator synthesis models with variable timbre
    • Filtered noise (4), phase distortion (8), state-variable filter (2), pulse-width modulation (2), hard sync (3), wavefolder (2), tanh compression, Dirac comb, phase modulation (15)
  • Oscillator timbre can be internally modulated by envelope, velocity, and LFO
  • Tremolo LFO with variable depth and 4 shape options
    • Can be applied to both envelope CV and oscillator
  • Changed how velocity modulates envelope amplitude: new PEAK VEL MOD sets the degree of velocity scaling for the envelope’s attack-decay peak only, leaving the sustain level unaffected, to allow direct control over envelope ‘punch’
  • New FILTER mode for the hold pedal: part receives notes only when the pedal is in the state selected by HOLD PEDAL POLARITY, and latches any notes that are “silently” released. Allows using the pedal as a part selector!


  • Wider range of envelope segment times: min 1ms, max 5s
  • Envelope uses buffered rendering and linear interpolation for higher audio quality
  • Display optimization
    • Minimize redraws by switching active character only after completing a brightness PWM cycle
  • Replace transposable checks with a note routing strategy that gives direct priority to the recording part
  • Disable LFO frequency variability between voices of the same part
  • Reduce CV/gate sample rate from 8kHz to 2kHz
  • Reduce loop/step sequencer note count from 31 to 30
