Introduction

The Malgorithm is a modular bit depth and sample rate re-

duction processor, colloquially known as a “bitcrusher”.  These 

processes offer time- and amplitude-domain quantization of an 

incoming audio signal, with the optional addition of a bitwise wave-

shaping stage. Malgorithm offers voltage control of each dimension 

of quantization for maximum modular utility. This device was de-

signed to maximize control of a non-ideal digital audio processor, 

for creative applications of nonlinearity, discontinuity, aliasing, and 

quantization. This module is also used to bring external signals into 

aesthetic compliance with the Harvestman system.

Configuration

The Malgorithm occupies 9HP of rack space and requires a 

“Eurorack”-style power distribution board. When connecting the 

power cable to your enclosure, orient the red band of the moduleʼs 

power cable to point towards the -12V power rail. If you experience 

diffi culty with the moduleʼs odd front panel measurement, you may 

solve this by adding another odd-measured Harvestman module to 

the system.

The Harvestman modules, due to heavy use of digital circuitry, 

could benefi t from the use of a dedicated 5V power supply. If you 

have such a supply available on your power bus, move the power 

jumper on the circuit board TOWARDS the edge of the board. All 

modules are set by default to use the onboard voltage regulator 

(jumper setting AWAY from the edge of the board.)

* Removal of motherboard 

from module assembly is NOT 

recommended unless a jumper 

change is necessary.
