Logic Gate

Four boolean operators on a pair of gate signals. Feed it two gates and it hands back their AND, OR, XOR, and inverted-A in parallel — the glue for building conditional triggers, interlocked rhythms, and gates that depend on two things happening at once.

How it works

Each input is read as a gate: anything above 1V counts as true. The outputs then report the logic of A and B, swinging to 10V for true and 0V for false. It's purely combinational — no clock, no memory — so the outputs track the inputs instantly.

Inputs & outputs

• A, B — the two gates to compare; patch clocks, sequencer gates, envelopes, or anything that crosses 1V.
• AND — high only when both A and B are high; requires two things to fire at once.
• OR — high when either is high; merges two trigger streams into one.
• XOR — high when exactly one is high; drops out when both fire, carving syncopated, interlocking patterns.
• !A — the inverse of A; high whenever A is low.

Tips

• Patch a steady clock to A and a slower gate to B, then take AND to gate the clock on and off rhythmically.
• XOR two clocks at different divisions for shifting, polyrhythmic gate patterns.
