Buchla U.S.A. - Ziggy

A new standalone Buchla instrument is not exactly an everyday occurrence. Ziggy takes one of the company’s central ideas — the Complex Oscillator — and builds a compact instrument around it, with analog sound generation, digital control, preset memory and a very hands-on front panel. No patch cable spaghetti required, no modular case needed. Just the Buchla way of doing things, folded into a self-contained desktop synth.

Central here are two analog oscillators — a Complex Oscillator and a Modulation Oscillator. The Mod Osc can run slowly for modulation duties or up in audio range for AM and FM, while the Complex Oscillator starts from a sine wave and moves into spike, square and sawtooth blends, with wavefolding in the Timbre section for that animated Buchla flavour. The signal then heads into Ziggy’s Low Pass Gate — part filter, part amplifier, and a big part of why plucks, pulses and percussive tones feel so distinct on this kind of instrument.

Modulation is handled in a very immediate way. Instead of patching with cables, you assign movement by holding buttons, moving sliders and setting amounts with the encoder. The main source here is the Cycler: somewhere between envelope, LFO, clocked shape generator and random modulator. It can animate pitch, timbre and gate behaviour, and the Uncertainty control lets you add controlled randomness to speed, shape, width and height. There is also an extra XLFO, MIDI pressure and CC control, plus CV inputs for gate, pitch and modulation.

Ziggy can be played on its own, sequenced from MIDI or USB, driven from 1V/octave CV, paired with a Buchla LEM 218, or dropped into a Eurorack-heavy setup. Scales, alternate tunings and quantized pitch sliders make it easier to stay musical if that's what you're after, while the more chaotic modulation options are always close at hand if you're reaching for random. Local Suspend can work as a neat performance trick: move several controls without hearing the changes immediately, then release them all at once.

Digital effects finish the sound with reverbs, delays, chorus, pitch shifting, flanging and related variations, controlled from a simple wet/dry knob and size macro. Programs can be saved and recalled, and a WebMIDI browser app handles editing, patch archiving and firmware updates. There is even an external audio input, so outside signals can be mixed into the Low Pass Gate path. Finally, it's also important to mention that Ziggy is powered over USB-C, so a power bank, computer or suitable wall adapter is enough to run it. That makes this lovely unit sort of portable, which is extremely nice!

Ziggy feels like a small Buchla instrument in the proper sense — playable, odd, elegant and full of lively interactions. It does plucky percussion, strange strings, animated basses, sharp little sequences and drifting electronic tones with a very clear personality. A lovely weird little flying saucer from the West Coast brimming with all things Buchla and we're all here for it!
