Maths soft-syncs to a sawtooth oscillator by patching it to the lag input in audio-rate cycling mode

Procedure L3Craft E · Modular, Eurorack, grooveboxes & dawless

Soft sync on Maths: cycle CH.1 or 4 at high audio rate in full exponential mode, then patch an external sawtooth oscillator to the lag/signal input (not the trigger). Adjusting RISE and FALL modulates the sync-sound range. Unlike hard sync where the slave is reset abruptly, Maths soft sync gradually influences the slave cycle duration, producing softer harmonic locking effects. Adding gentle LFO modulation to RISE, FALL, or BOTH creates animated sync-sweep timbres.

Examples

CH.1 or 4: CYCLE on, full EXP, audio rate. Sawtooth VCO → CH.1 lag/signal input. Adjust RISE/FALL to explore sync harmonic range. Slow LFO → RISE CV for animated sync sweep.

Assessment

What distinguishes the Maths soft sync patch from hard sync between two oscillators, and why is a sawtooth specifically recommended?
