# Peak comparison: two slopes, one waveform

The GTS PEAK circuit combines the upper internal slope with the lower slope at PEAK IN by taking their instantaneous maximum.

## Start here

Lower the monitoring level before patching. These are documented patch designs, not claims of hardware audition.

Unless this recipe uses the right Mix Pro for control voltage: center its DC offset, zero unused channels, and bring up only the cabled audio inputs. Connect Audio Interface MIX OUT to your normal monitoring chain.

1. Cycle both GTS channels in the audio range with roughly symmetric slopes. Tune near unison.
2. Bring up the Mix Pro slowly; PEAK carries a unipolar composite waveform.

## Cables

1. GTS XL upper END OUT → GTS XL upper TRIG IN.
2. GTS XL lower END OUT → GTS XL lower TRIG IN.
3. GTS XL lower OUT → GTS XL PEAK IN.
4. GTS XL PEAK → Edelweiss right Mix Pro IN 1.
5. Edelweiss right Mix Pro OUT → Audio Interface AUX IN.

## Listen for

A changing combined waveform as the two cycles drift relative to each other.

## Play it

Move lower FALL from near-unison to an octave relationship, then change upper symmetry.

## If it misbehaves

If you hear only one stable waveform, check lower OUT into PEAK IN and detune the channels slightly.
