Mutable Instruments Ripples
Multimode filter with character inspired by Japanese classics
8 HP Eurorack module
Ripples is a voltage-controlled multimode filter offering high-pass, band-pass, and low-pass outputs with switchable 2-pole/4-pole slopes. It features a soft-clipping input stage, voltage-controlled resonance, and a built-in VCA on the low-pass output for complete subtractive synthesis patches.
Features
- Simultaneous HP, BP, and LP outputs
- Switchable 2-pole/4-pole slopes
- Soft-clipping input with gain control
- Voltage-controlled resonance with clean self-oscillation
- Built-in VCA on LP output
- V/octave tracking over 4 octaves
- Japanese 80s filter character
- Dual input mixing
