Haible Dual Wasp Filter

The Haible Dual Wasp Filter is Random*Source's Eurorack adaptation of Jürgen Haible's Wasp filter, after the famous CMOS VCF: two of them with their distortion, in series or in parallel, sold as a DIY kit.

Key features

• Two Wasp filters, A and B, each with CUTOFF, RES, its input level and CV attenuator
• TYPE blends lowpass to highpass or bandpass (its switch); DIST sets the distortion, before or after the filter (jumpers)
• SYNC: the left side's cutoff and CV drive the right side too
• MODE blends from serial to parallel, under voltage control with its attenuverter; OUT mixes both, OUT A and OUT B give each
