Double Knot is an all analog synthesizer which is both sequencer and voice. It can be thought of as something of an indeterministic "groovebox". A stereo instrument with two identical voices that can give different rhythms, melodies or cross timbral slaps. The idea of this instrument is to invite reconciliation of linear and nonlinear systems, and to encourage the building of multiple-feedback synthesis architectures. User interface is with rotary potentiometers, switches, and banana cables. Patching puts are banana ports of round brass tube. Clock in and out are 3.5mm jacks bearing 5V square waves. Audio output is stereo 3.5mm line out.
