Beyond Phaser: Djupviks The Qu's Wild Sonic Mutation

video upload by Lesjamusic

"Welcome to the semi-official guide for Djupviks The Qu — a Eurorack modular phaser inspired by the legendary Lovetone Doppelganger but expanded for deep audio experimentation.

✅ Optical Phaser Technology: Organic, throbbing modulation via LEDs and light-dependent resistors (LDRs).
✅ Dual CV Inputs: Easy stereo modulation or complex, independent control.
✅ Distorted Output: Diode clipping adds gritty, wavefolded textures.
✅ Dry Signal Bypass: Switch from phaser to vibrato and glitchy experimental textures.
✅ "The Qu" Mode: Inspired by an obsolete telephone tracking chip (LM567), it creates chaotic, unpredictable soundscapes, blurring modulation and synthesis.

Named after the alien species from C. M. Kosemen’s speculative evolution book, All Tomorrows, The Qu module embodies radical audio transformation—visually enhanced by Kosemen's own front-panel artwork."

"Off screen, the SH-101 is acting as the sole sound source. That's fed into both DJupviks phasers (The Qu and Neo Tokyo), which are modulated by Bristol Bloodhound Mk 2 and Tangram. Bunker Archeology smears it all up. Soma Cosmos and Walrus Audio Slöer make everything dreamy again."

"The red skiff is alive! A full 104hp of ‪@vikingsade‬ Djupviks modules, with my latest additions being Clot and Bunker Archaeology.

These modules crave audio rate modulation, and so ‪@atovproject‬ Dual Harmonic was on hand to provide, along with the LX-Euclid for gate sequencing the Djupviks Beneath the Bush of Ghosts lofi sampler. ‪@Dreadbox-synths‬ Nymphes also as a sound source alogside the DHO.

With apologies for the mouth-breathing - not over my winter cold.

"Djupviks The Qu proving it can do traditional phaser sounds as well as maniac dirt.L, with the help of Bela Gliss on modulation.

SH-101 reminding me no matter how many VCO/VCF/ADSR combos I buy, it’s still the ultimate monosynth.

Apologies for the sloppy playing - I’m better at programming synths than playing them.

Dirt and colour from Sealegs, Gen Loss, CXM 1978 and OTO Boum."

LOFI quad sampler ISD1820 ic

DIY pcb and panel only as of 03 MAR 2023.

Beneath the Bush of Ghosts is a 26hp Quad Lo-fi sampler based on the ISD1820 IC chip which is an old answering machine chip. This module is inspired by several other projects based on the ISD1820 chip. Each of the four channels are identical to each other with some sneaky normalisation going on between the channels for extra fun!

There is a mix output which combines all the dry inputs with the sampler outputs, while the individual outs of each channel only contain the sampler output. Each individual output is cross modulated with the channel next to it in pairs, so 1-2 modulate each other and 3-4 the same way. Each output is also normalled to the following input, 1-2-3-4 and 4 goes back to input 1. This means you can do generation loss (i.e. disintegrating loops) with some clever patching. Each channel has a filter with lowpass to the left and high pass to the right, as well as a pitch knob with a dedicated cv input and attenuator. There is also a dedicated trig input for each channel, and control buttons for the following functions: record in, momentary play and full play of the sample. The trig inputs need a +5v gate to operate. Samples can be played on loop by engaging the ‘Loop’ switch at the top of each channel.

Recording instructions: In order to record you need to turn the loop switch off, set the pitch to around the 10 to 2 o’clock (you can experiment with this), the CV knob will usually influences the sample speed so make sure it is fully CCW. Insert an input signal (or use the looping sampler next to it) and hit record, the LED will turn off while recording, and light up again when the memory of the chip is full. It’s a simple as that!
