Mutable Instruments Ripples Full DIY Kit (Brand New)

This Ripples Magpie Modular Full DIY Kit is brand new, never opened or fiddled with.

Comes with all the necessary components to build your own Ripples Magpie Modular, with the classy white panel.

Note: I ship with signature required. Let me know ASAP if you do not want the signature required (though it’s a good idea to use signature requirement).

Ready to ship ASAP.

Product Description

The kit includes the panel, a limited edition PCB (blue w/gold immersion finish, rogan knobs, alps pots, all necessary components, mounting hardware and power cable.

Don't worry if you drop an SMT part-- for 0603, 0805 and 1206 packages, we include an extra !! If you don't lose SMT parts, keep the spares to build up your shop inventory

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.

Controls

• Cutoff frequency, 18Hz to 18kHz
• Resonance (self oscillation at 80%)
• Attenuverter on Frequency CV

Inputs and outputs

• Signal in
• Frequency CV 1 (1V/Oct)
• Resonance CV. Self oscillation starts at 4V. Control voltages above 5V are non-linearly compressed, for fine control of resonance overdrive
• Frequency CV 2 (with bipolar attenuator, from -1V/Oct to 1V/Oct)
• VCA level. Control voltages above 5V are non-linearly compressed.
• 2-pole BP output
• 2-pole LP output
• 4-pole LP output
• 4-pole LP output attenuated by VCA

Technical characteristics

• Fully analog, based on SSM2164 low noise/distortion quad VCA chip, and LM13700 OTA for that extra bit of non-linearity.
• Frequency CV inputs impedance: 100k.
• Audio input impedance: 75k.
• Resonance and VCA CV input impedance: 30k.
• Open-source hardware.
