Liminal Sound Devices launches Burg analog semi-modular synth with touchpads, light sensors

Liminal Sound Devices, a small Munich-based developer, introduced Burg, a compact experimental semi-modular analog synthesizer built around 18 individual modules and designed for tactile, exploratory play. The maker bills it as “a new, experimental semi-modular analog Synthesizer and multi-FX unit playable with touchpads and light sensors,” and the hardware packs a large control surface: sources list 26 inputs, 29 outputs and 38 physical controls alongside a separate specification of 55 patching points.

The Burg’s routing and modulation count is notable for a unit aimed at desktop performance and patch experimentation. Synth Anatomy’s description states “There are 55 patching points in total, making possible combinations virtually limitless,” while the original announcement itemizes 26 inputs and 29 outputs. The unit’s connectivity is paired with two light-dependent controllers and a capacitive touch interface intended to generate multiple CV and gate streams for on-the-fly performance.

Performance gestures live on the touchpads. “An intuitive touchpad interface gives easy control over multiple CV and gate signals, and is Burg’s main modulation source,” according to the product copy, and the instrument also features “two light-dependent controllers for generating all sorts of unique behaviours.” Those interaction layers are presented alongside traditional synth building blocks so users can use Burg as both a controller and a processing voice.

Sonically, the Burg is described as leaning toward grit and texture rather than pristine purity. “The Burg’s sound leans towards the dirty and noisy side, which is due to the combination of a pingable Wasp filter, two crunchy delays, distortion, and overdrive amps.” That stack of effects and the inclusion of a pingable Wasp-style filter point toward aggressive modulation patches, feedback experiments and processed external signals.

Burg is positioned as a multi-role device: “It’s a standalone synth voice, complex multi FM processor, and controller for external gear in one.” The design supports external audio as well — “Plugging in an instrument, mic or other audio source, the signal can be modulated with various effects and filters” — and the DIY-friendly layout lets builders modify “other modules by exchanging components on the back plate.” The project is pitched as useful for “producing dynamic melodies, harmonic drones, weird nosies and outer space sound effects,” and the maker states that “Burg provides all the necessary tools to start the experimentation joinery into modular synthesis.”

Pricing and production follow the boutique route. The product page lists a fully assembled Burg at 650€ and a DIY version for 350€, while the developer notes that “They are not mass-produced but only in mini-batches on demand.” Availability text on the product page appears in different places as both “Liminal Sound Devices Burg is available now on the official website: a fully assembled version for 650€ and a DIY version for 350€” and “Available to preorder now.”

For players looking for a hands-on semi-modular that emphasizes touch and light as primary controllers, the Burg is clearly aimed at a workshop-minded crowd rather than the mainstream. “It’s not a synth for everyone, but it looks fun and sounds unique,” the product copy concludes, as the Munich builder moves a compact, noisy, and highly patchable voice into the boutique semi-modular field.
