Mutated: Ripples

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.

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.
