Krischer is a small, hand-built analog synthesizer maker based in Paris, France, known for minimalist drone and oscillator-based instruments sold directly to musicians through online marketplaces rather than traditional retail. The designs lean toward pared-down interfaces — top-hat knobs, illuminated switches, and a handful of controls — housed in compact, inexpensive enclosures aimed at drone, ambient, and experimental music.

The product line centers on simple analog oscillator boxes. The Syclope is a single-oscillator unit with a CV input for pitch. The Analog Polyphonic Synthesizer uses three sawtooth oscillators; its V2 revision added CV inputs to allow melodic sequencing alongside drone use. The M8 expands the concept to eight tunable sawtooth oscillators with individual on/off switches and no filters or envelopes, intended for stacked drones and minimalist textures. Krischer has also offered utility devices such as a MIDI USB to CV/Gate converter and an MS-20-style filter clone, and the maker will add custom CV inputs on request.

Because each unit is assembled by hand, Krischer's output is low-volume and its distribution informal — instruments are typically found through its Reverb shop, Etsy, and eBay, and the brand maintains its public presence primarily on Instagram and Facebook.
