2hp Pitch – Cheat Sheet

Overview

2hp Pitch is a compact Time Domain Pitch Shifter module for Eurorack with built-in Wow & Flutter modulation. It allows shifting of pitch (±2 octaves), modulation of pitch "instability," and wet/dry mixing. Ideal for creative audio processing, lo-fi effects, and harmonization.

Inputs, Outputs & Parameter Summary

Name	Type	Voltage Range	Description
Audio Input	IN	10Vpp	Main audio signal input (patch audio here to be pitch shifted).
Audio Output	OUT	-	Main processed audio signal output.
W&F CV Input	CV IN	+5V	Voltage control for Wow & Flutter depth (modulates instability).
Mix CV Input	CV IN	+5V	Voltage control for dry/wet blend.
1V/OCT Input	CV IN	+5V	Standard 1V/oct pitch input; extends pitch shift control externally.

Knob / Control Summary

Name	Position	Function
W&F Knob	Fully CCW → CW	Controls wow & flutter random modulation depth. CCW = none, CW = maximum.
Mix Knob	Fully CCW → CW	Mixes between dry (CCW) and wet (CW) signal. Any blend allowed in-between.
Pitch Knob	CCW, Noon, CW	Shifts pitch -2 octaves (CCW) to +2 octaves (CW). Noon = no transposition.

Performance Tips

Combine VCO: Create harmonies from a single oscillator by pitch shifting and mixing both.
Layer with Loop: Add tape-style warble to loopers or harmonize sampled material.
Use with Play: Send in drum loops/samples, pitch shift for unexpected timbral changes.
Lo-fi Combo with Freez: Combine Freez and Pitch for ultra-lo-fi, modulate both for unique artifacts.

Voltage Reference

W&F CV Input: 0–+5V
Mix CV Input: 0–+5V
1V/Oct Input: 0–+5V (tracks one octave further than the knob range in either direction)
Audio Input: ±5V (10Vpp typical Eurorack synth audio levels)

Installation Notes

Align red stripe of power cable with white marker on PCB.

What is Wow & Flutter?

Wow & Flutter is a modulation effect simulating pitch instability due to tape/turntable irregularities, lending warmth or 'lo-fi' character.
