Mutated: Ripples

Mutated: Ripples - This DIY Ripples PCB is a liquid, Roland-esqe filter. Great intro to SMT.

This is a PCB set in the Eurorack format.

Availability: In stock




3 filter modes are available: 2-pole band-pass, 2-pole low-pass, and 4-pole low-pass.

Self-oscillation is available for all modes and produces a clean sine-wave on the LP4 output. Unlike many classic 4-pole designs, this filter does not suffer from “loudness drop” when resonance is increased. The resonance loudness compensation circuit brings a slight tone coloration reminiscent of the Roland SH/Jupiter filters, with a very round and “liquid” resonance.

The 4-pole low-pass output is additionally sent to a VCA. This makes Ripples a good “final stage” module for an inexpensive/space-constrained subtractive synthesis synth voice.


NOTE:  All Mutated modules are designed by Émilie 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.

A+Review by Willis
These are excellent quality. Mine were blue. Unlike some other suppliers, each and every part designator is legible, meaning I don't have to squint over some ******* Eagle file to try and figure out where everything goes. (Posted on 10/19/2017)

Nice board-- built with no issues after some careful preparation. The silkscreen on mine was missing polarity markings for diodes and chips but had all part numbers. The mouser cart here has correct part counts but the part designators have import errors so don't use them directly. I printed out the silkscreen from the eagle files on git hub in order to build correctly. The board itself works great though! Be sure to order jacks, pots, and the 2164 ic, and find any backprdered parts elsewhere. (Posted on 8/12/2017)
