About
Steckfeld SF1 is a modular synthesizer you build by hand.
Parts sit on a plate in a grid. Plug them in, run lit cables between them – red for sound, blue for control – and see the whole sound at once. Tap a part and the programmer comes in: a screen and four real knobs.

• Sources: Analog, Wavetable, FM with four operators, a plucked String, Audio In
• Effects: Filter, EQ, Compressor, Distortion, Chorus, Delay, Reverb
• Utilities: 16-step Sequencer, Arpeggiator, Envelope, LFO, MIDI In, Junction, Cover
YOUR PATCHES, KEPT

• Its own clock or one from outside; sends clock, follows start and stop

AN INSTRUMENT WITH CHARACTER
