MATHS extracts a gate from a CV by comparing it to a threshold and firing an instant EOR pulse

MATHS can act as a voltage comparator that outputs a gate whenever a signal crosses a threshold. In the ‘A New Take’ recipe: send the signal to be compared to CH2’s Signal Input; set CH3’s panel control into the negative range to define the threshold (a negative offset the signal must overcome); patch the SUM output to CH1’s Signal Input; set CH1 Rise and Fall to zero. When the summed signal goes slightly positive — i.e. the input exceeds the threshold — CH1 fires immediately and its EOR trips, giving the extracted gate. Raising CH1 Fall widens the extracted gate; raising CH1 Rise sets how long the signal must stay above threshold before the gate trips. This turns any modulated CV or audio envelope into a rhythmic gate pattern.

Examples

Feed a drum envelope to CH2, tune CH3’s negative offset as the threshold, take the gate from CH1 EOR: a gate fires on each hit that exceeds the threshold.

Assessment

Which channel sets the comparison threshold and which output carries the extracted gate? What do CH1 Rise and CH1 Fall each control in the extracted gate?
