Signalform builds Eurorack modules in a canal-side workshop in Rotterdam. No menus, no presets, no screens — just voltage, brushed aluminium, and your two hands.
The panel on the right is live. Power it on.
Every Signalform module speaks the same electrical language, laid down in 1969 and never improved upon. Watch a control voltage walk the chain: oscillator to filter to amplifier, with a low-frequency ghost bending the cutoff on its way through.
The module above. Analog triangle core, ladder filter, one LFO with real opinions. The whole quartet in one panel.
€389Triangle-core VCO with thru-zero FM. Stays in tune through a Rotterdam winter — we test on the loading dock.
€249Four-pole transistor ladder. Self-oscillates into a sine pure enough to tune the rest of your case by ear.
€279Attenuverter, mixer, slew, offset. The module nobody demos and everybody patches first.
