# Sampled noise, restrained pitch

A clocked GTO Stepped section captures noise; a Mix Pro scales the held voltage before it controls NTO.

## 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. GTS upper: 1–3 Hz. GTO left Stepped: cycle off, SMPL up (sample mode), RATE fully fast.
2. Mix Pro: offset centered at zero, unused channels zero, channel 1 initially zero. Raise it only enough for a small pitch range.

## Cables

1. GTS XL upper END OUT → GTS XL upper TRIG IN.
2. GTS XL upper END OUT → Dual GTO left Stepped SMPL.
3. Dual GTO S/H source → Dual GTO left Stepped IN.
4. Dual GTO left Stepped OUT → Edelweiss right Mix Pro IN 1.
5. Edelweiss right Mix Pro OUT → NTO 1V/OCT.
6. NTO SINE → Audio Interface AUX IN.

## Listen for

A sequence of held, unquantized pitches with fresh independent samples. This is not a Brownian walk.

## Play it

Vary the Mix Pro depth between tiny detuning and wide intervals.

## If it misbehaves

Constant pitch: SMPL in the center ignores sampling; also confirm the S/H noise source reaches Stepped IN.
