Maths detects and holds signal peaks by slewing at a slow symmetric rate and reading Signal OUT, with EOR firing a gate at each peak

To detect peaks on Maths, patch the signal to CH.1 Signal IN and set both RISE and FALL to a slow rate (around 3 o’clock). Because the channel can only follow the input as fast as RISE/FALL allow, Signal OUT lags and holds toward the extreme (peak) values rather than tracking every fast excursion, giving a peak-hold-like output. EOR fires a gate each time the rising portion completes — i.e. at detected peaks — providing a trigger derived from signal maxima. This contrasts with the envelope follower, where FALL is set fast for tracking; here symmetric slow slopes emphasise holding the peak.

Examples

Signal → CH.1 Signal IN. RISE and FALL both to 3 o’clock. Take held peak level from CH.1 Signal OUT; take a gate at each peak from EOR OUT.

Assessment

Which RISE/FALL setting turns a Maths channel from an envelope follower into a peak detector, and what does the EOR output give you in this patch?
