stay here for the video series on the hexagen2612, or use the menu to read blog posts about the process
the Boney Circuitry hexagen2612 Ripper (still in breadboard form) is a semimodular 32-key analog/digital hybrid monosynth that really rips
it uses primarily CMOS logic chips and a YM2612 digital FM chip, and is controlled using an Arduino mega2560 and built into a toy keyboard, to provide a unique sound well suited to bass and lead patches
it features a voltage controlled oscillator built around a 4046 phase-locked loop chip that boasts 3 waveforms: “rampoid” (a saw that morphs into a triangle), pulse with variable pulsewidth, and sine
a clone of the infamous EDP Wasp synthesizer’s voltage controlled filter with 4 filter types—low pass, high pass, band pass, and notch—based around a 4069 hex inverter, plus a ripping distortion
an idiosyncratic shapeshifting low frequency oscillator of my own design, which morphs between a rampoid-style shape and a pulse-type shape and mixes them together to create unique rhythms
a handful of extra audio sources for processing through hexagen’s filter and distortion, including white noise, audio in, and an extremely cool electromagnetic sonifying coil a la Christina Kubisch
plus key pressure voltage control, an ADSR envelope, note-by-note tuning, vibrato, pitch bend, audio routing control, an LCD screen, and of course the YM2612 itself. check back for more videos on these features and beyond to come, and stay boney!
