The low-pass filter design used in the Benjolin and as one half of the Twinpeak filter in the Blippoo Box and Hordijk modular systems is designed to exhibit certain chaotic properties when overdriven. By overdriving the Benjolin's line-level external audio input with the "modular level" square wave output of the first oscillator (which becomes saw-like with the addition of even harmonics from said overdrive), resonant bifurcations are created as audible subharmonics of the oscillator frequency as the filter resonance is increased and the cutoff frequency is modulated.

The control portion of the patch began as a crude attempt to imitate the Blippoo Box's sample-and-hold arrangement by using the XOR output of the Benjolin to trigger the Stepped Generator, which is sampling a mix of signals from throughout the patch; extensive cross-modulation to and from the Benjolin, the Smooth Generator, and the Voltage Controlled Slope is in play. The patch is played in real time, with numerous knob turns and manipulation of the Cycle switch on the VCS and the Loop switch on the Benjolin.

This recording is one improvised take. Eventide EQ65 provides some corrective EQ, Cherry Audio Stardust provides delay and reverb, and Martinic Colorsound Tremolo indulges my toxic boomer trait of liking a little slow auto-panning now and then.

Dedicated to Rob Hordijk shortly after the anniversary of his passing. Rungle with you on the other side, space cowboy.
