Mutated: Frames

Mutated: Frames- This DIY Frames PCB is complex keyframer/mixer with several use cases.

This is a PCB set in the Eurorack format.

Availability: In stock




The heart of Frames is a 4-channel digitally controlled analog VCA. Through flexible input/output mixing and normalling options, it can be patched to serve the following purposes (among others):

  • 4-channel attenuator/VCA.
  • 4-channel mixer.
  • 4-channel programmable CV source.
  • Quadraphonic panner.

But what makes it truly unique is the way in which channel levels can be controlled, using a technique inspired by computer animation. Frames allows up to 64 configurations of the 4 level knobs to be stored and recalled throughout the course of its big "Frame" knob. By rotating the knob (or sending a CV to the Frame modulation input), the configurations are morphed into one another.

To fine-tune the animation and get varied morphing or sequencing results, the following options are available for each of the 4 channel:

  • Easing curve (stepped, linear, exponential, logarithmic, sine, bouncy)
  • Attenuation response of the level knob, from linear to logarithmic

With a bit of patching and imagination, Frames can also be repurposed as a 4-channel sequencer, a multi-stage envelope generator, a trajectory generator for quadraphonic panning...


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.
