Melotus Versio

Stereo texturizer using granular processing

designed for grain delays, accompaniment, and

transformation of any and all audio.

Type Granular texturizer

and delay

Size 10 HP

Depth 1.5 inches

Overview

Melotus Versio is a stereo texturizer that uses granular processing to transform and

reshape sound. It’s granular for Doombient. Designed to be played by hand or

manipulated within a patch, Melotus can act as everything from a grain delay to a

completely transformative texturizer with extensive grain control and manipulation of

triggering, direction, and randomness. Audio can be ltered with a lowpass/highpass

combo lter that adds haunting shimmers and subharmonics. Plus, grains can be frozen

by hand or with triggers and gates, or clocked to create rhythmic eects. Plus, Melotus

Versio is a DSP platform and can be transformed into a completely dierent eect by

loading a growing number of alternate rmwares, completely free—or program your own

rmware with our open-source documentation.

Etymology

Melotus: from Latin Meles for “badger” Also, a contraction of Melocactus, a genus of

prickly cactus.

Versio: from Latin for “versatile”

“Versatile spiky badger”

Color code

On boot, the MV’s LEDs will shine with this color

pattern to indicate that it is running the current MV

rmware.

Installation To power your Noise Engineering module, turn off your case. Plug one end of your ribbon cable into your power board so that the red stripe on the ribbon cable is aligned to the side that says -12v and each pin on the power header is plugged into the connector on the ribbon. Make sure no pins are overhanging the connector! If they are, unplug it and realign.

Power If your Versio looks like the left picture, it requires 70mA +12v and 70mA -12v. If it looks like the right picture, it requires 125mA +12v and 10mA -12v. Versio does not use the +5v rail.

Interface Blend: Dry/wet balance control. When turned fully left, the unmodified input signal is passed through. Fully right, only the processed signal is heard. Points in the middle give you a mix of both. Sparse: Changes the number of grains from 24 at minimum to 1 at maximum. Grains become more obvious as the knob is turned up. Tone (bipolar): Filter and effects. To the left of 12:00, Tone acts as a lowpass filter and adds in detuned subharmonics.

Patch Tutorial Patch 1: Texturizer This patch will take an incoming sound and granularize it, creating stereo effects and backgrounds, or completely new sounds. 1. Set Blend, Tone, Length and Delay to 12:00. 2. Set Regen to minimum, and Sparse and Cohere to maximum. 3. Set the switches to “Fwd” and “Hld”. 4. Patch a melodic sequence into In L (and In R if stereo), and patch Out L and R to your mixer.

Input and output voltages All CV inputs expect 0-5 V. All pots act as offsets and sum with the input CV. The FSU gate input responds to signals above +2 V. The audio inputs clip around 16 V peak to peak. Updating Firmware Melotus Versio’s firmware can be changed to a growing number of alternate firmwares via our firmware webapp. In the unlikely event that the need arises, firmware patches for Melotus will also be available on that site.

Design Notes We’ve long wanted to create something in the realm of granular processing, and the Versio platform seemed like the perfect place to create something grainy. In fact, it was only one of quite a few granular concepts we’ve been exploring—we decided to go with Melotus because it instantly gave us some wild and beautiful results, but this probably won’t be the last time you hear something granular from us. Initially, Melotus started out as a pure grain delay.
