Maths acts as a voltage-controlled slew/portamento processor with VariResponse-shaped curves

Patching any signal to Maths Channel 1 or 4 Signal IN converts the channel into a slew limiter/portamento. RISE controls the rate of upward transitions; FALL controls downward transitions — both independently voltage-controllable. VariResponse shapes all curves from log to exponential. A common use is pitch portamento: patch V/Oct from a sequencer through Maths to a VCO V/Oct input. Unlike a fixed-rate portamento, Maths allows different rates for pitch rises vs. falls.

Examples

Seq V/Oct → CH.1 Signal IN. CH.1 Signal OUT → VCO V/Oct. Adjust RISE for glide up, FALL for glide down. Patch an LFO to RISE CV IN for variable-rate portamento.

Assessment

What distinguishes a Maths slew patch from a typical fixed portamento, and how do you set different glide rates for pitch rises versus pitch falls?
