Meet Ziggy: a Desktop Synthesizer from Buchla USA

Accessible, Advanced, Easel-Inspired

Perfect Circuit · 05/05/26

Just in advance of Superbooth, Buchla USA has announced Ziggy: a new desktop synthesizer that borrows inspiration from prior Buchla designs. Ziggy is a monophonic synthesizer with an analog sound production path, digital end-of-chain effects, and extensive digital control—resulting in a highly flexible instrument capable of a broad range of sounds.

Notably, Ziggy abandons the modular/control-voltage-centric workflows of Buchla USA's recent series of Music Easel reissues in favor of a self-contained design. Perhaps most remarkably, they have introduced it at a price of $999: currently, the most affordable complete instrument in their catalog. And naturally, early demonstrations of the instrument showcase a broad range of sounds: from classic Easel-esque bongos, plonks, and unusual animated tones to timbrally rich and complex leads and bass lines. While its internal signal path does resemble the Music Easel, it seems to be aimed at musicians who want a touch of the experimental-leaning Buchla-esque flavor in a MIDI-controllable, preset-capable standalone instrument.

So, what's inside Ziggy? The center of the instrument is the familiar Complex Oscillator: a multi-waveform sound generator with an integrated wavefolder, truly the foundation of what many consider to be "the Buchla sound." It allows the user to blend between a sine wave and a selection of other shapes (spike, saw, and square), and to apply the wavefolder to produce a vast range of continuously variable timbres. A dedicated modulation oscillator can be used to apply amplitude or frequency modulation to the principal oscillator, at low or high frequencies—resulting in everything from continuous fluctuations to clangorous, inharmonic tones.

The Audio Blend control determines the balance between the Complex Oscillator and a selectable secondary sound source prior to the low pass gate. This allows the user to mix in external signals, to create layered textures that use the Modulation Oscillator as a sound source, or to simply blend in a touch of noise. Ziggy's Gate is an analog low pass gate with an integrated envelope generator. The envelope features continuously variable shape via the Gate Control slider, and variable duration via the Env Width control. The Gate Control slider also offers a means of using the Cycler (more on that soon) or incoming key pressure information to directly control the Gate's level.

The end-of-chain digital effect generator offers a selection of stereo effects, ranging from panners to filters, delays, reverbs, pitch shifting, flanging, and more. A generic "size" control acts as a macro for each effect option, mapping to different parameters for each effect preset.

Naturally, a Buchla-inspired instrument wouldn't be complete without a complex means of defining musical structure: the way that sounds change over time. Alongside the modulation oscillator, Ziggy includes a host of other modulation sources designed specifically for this instrument concept. Perhaps most notable is the Cycler, a general-purpose modulation source that can be used for LFO or envelope-like functions, random generation, pattern generation, and more. It offers continuously variable speed, cycle shape, "width", and "height". It can be used to trigger the Gate's envelope, or can directly modulate various other aspects of the instrument's sound structure. Additionally, it features an integrated "Uncertainty" function, in which randomness can be applied to any combination of the Cycler's parameters—turning it into a complex source of control, capable of utility functions and ever-evolving complex control structures.

Ziggy also features an XLFO—an "extra" low frequency oscillator which can be assigned to modulate Ziggy's many modulation destinations. Modulation assignment is simple and gestural: simply hold the Assign switch and move the slider corresponding to the parameter you'd like to control. Additionally, many of the principal parameters feature dedicated switches for assigning common control paths, including special MIDI mappings, trigger routing, and more. Speaking of which, Ziggy offers multiple ways of integrating external control sources: it can accept gate, modulation, and pitch control signals from Eurorack or other semi-modular synthesizers, or it can accept MIDI via 5-pin DIN, 3.5mm Type A jack, or via USB-C. While this of course means that Ziggy can work with nearly any controller you have lying around, Buchla USA offers a special bundle deal pairing it with the LEM 218 V3 touch plate keyboard controller: a sensible pairing, given that several of its default outgoing CC assignments match up nicely with some of Ziggy's own default CC assignments.

Ziggy offers space for over 100 presets; LED-embedded slide pots offer visual feedback for settings, always keeping the instrument's status clear even as you switch between patches. A companion WebMIDI browser-based editor can be used to edit and archive patches—and also acts as a means for updating firmware when needed.

Not having yet used Ziggy ourselves, some details aren't 100% clear; however, Buchla USA promises comprehensive MIDI control, a simple/shallow menu structure, and a "quick, gestural means of assigning modulation and composing music." Overall, we're excited to see Buchla USA creating new designs—borrowing from their namesake's legacy while bringing new concepts and new means of interaction to the table. It leverages its self-contained design to enable levels of immediacy and reproducibility difficult to achieve in modular designs; and whlle it might seem odd to see "a Buchla" without an extensive array of modular patch points, there's no doubt that Ziggy is capable of some truly complex and unusual tones. It seems to represent an honest stab at answering the apparent market demand for an affordable, comprehensive Buchla-inspired instrument, and we're eager to see how it will be used.
