Déjà vu: Flexible Fader Control for Audio & CV│Bastl Instruments

video upload by Bastl Instruments

"Bastl Déjà vu is a Swiss knife for your Eurorack System that adds fader control to your modular system for many scenarios. It stands out as a simple yet powerful utility module that can do crossfading, mixing, signal boosting, voltage processing, attenuation or attenuversion. All that in 4HP and with the possibility to chain several of them to mix even more signals."



Powerful Voltage Utility module for voltage processing, attenuation, signal boosting, crossfading, and mixing

Déjà vu adds fader control to your modular system and it stands out as a simple yet powerful utility module that can do voltage processing, mixing, attenuation, attenuversion, signal boosting, crossfading and mixing.

All that in 4HP and with the possibility of chaining several units to mix even more signals.

SWISS KNIFE FOR YOUR RACK

Déjà vu has two almost identical channels A and B. Each channel has the FADER input and the ADD input and an output with light indication. The FADER MODE switch alters the behavior of the module, either attentuating or attenuverting the FADER input where the ADD input will be added to the processed FADER input. The last option is crossfading between the FADER Input and the ADD input which is great for creating performance oriented macro controls.

Q DRM - 4 – Four Analog Drum Voices for Eurorack Modular

video upload by HOX808

"Q DRM - 4 is an analog Eurorack module with four independent drum voices. Its Twin-T resonator design delivers 808-inspired bass, tom, and percussion sounds when triggered — from claves and rimshots to bongo- and conga-like tones. The color-coded controls let you dial in each voice’s fundamental range, while separate outputs per voice provide maximum flexibility for patching, mixing, and further sound shaping.

"Quad reverse sigmoid chaos module with CV inputs, sync controls and mixed outputs
https://www.nonlinearcircuits.com/mod...

single 1U version - https://www.nonlinearcircuits.com/mod..."

"This module is a set of 4 reverse sigmoid chaos circuits, running at different frequencies, there are pots to feed each section into another and influence, sync – sort of, the action. There are also CV inputs for each section which affect the reset or crossover timing, for the faster ones the results are obvious. For the slower ones, give it a few hours.

The reverse sigmoid circuits are similar in concept to the mackey-glass based design used in the NLC Frisson, but are greatly simplified to a bare minimum of parts. Simply an integrator, two all pass filters and a nonlinear stage with two feedback paths. The nice thing about them is you can use any capacitors you like, so long as all three are the same, and the circuit will work with no other mods required. The sections in this module use 1uF, 10uF, 2x 1000uF in series (so 500uF) and 2x 2200uF in series (so 1100uF).

They work quite differently to the Sloth chaos circuits, with a number of ripples or rolls between each attractor, also the three outputs track each other, the faster ones are delayed by a few seconds, the slower ones by minutes. The intent of having 4 different circuits running together with pots to get them to influence each other is to have a module that can create longer tracks with many different but related musical events happening and, of course, weird delayed CV effects. Think of a band where the members all do their own thing but every now and then the sounds and patterns connect and achieve structure, which slowly scatters and reforms in new ways.

Feel free to change the 1uF caps to a higher or lower value, similarly for the 10uF. Stack capacitors on top of each other to get 20uF, or use Tayda 22uF caps and stack them. See pictures on pg6 for info on which caps to change. Make sure the capacitors have at least a 25V rating or higher.

If you want to use larger values than 1000uF and 2200uF, make sure they will fit on the PCB and/or thru the panel holes (1000uF on PCB are 10mm diameter, 2200uF panel holes are 16.8mm)

There are also two difference rectifier circuits which output complex mixes of the individual chaos circuits."

1U REVERSE SIGMOID
DESCRIPTION/USAGE

6hp

This module is a reverse sigmoid chaos circuit; it can be built to run as a fast or slow CV source, or even as an audio/noise source. This is a single version of the four chaos circuits in the NLC How’s the Serenity module.

The reverse sigmoid circuits are similar in concept to the mackey-glass based design used in the NLC Frisson, but are greatly simplified to a bare minimum of parts. Simply an integrator, two all pass filters and a nonlinear stage with two feedback paths.

The nice thing about this design is you can use any capacitors you like, so long as all three are the same the circuit will work with no other mods required. The capacitors are marked ‘C’ on the PCB, 1uF is a good mid-range value to install, but 10uF, 22uF are good too albeit much slower. Lower values than 100nF get you into audio rate territory. Make sure the capacitors have at least a 25V rating or higher.

This works quite differently to the Sloth chaos circuits, with a number of ripples or rolls between each attractor, also the three outputs track each other, the faster versions are delayed by a few seconds, the slower ones by minutes.

The Input expects a positive CV, negative going CVs won’t hurt but will have no effect. The CV signal feeds into the first all-pass filter stage via 10k and a diode, this is different to the method used on How’s the Serenity. On slower builds, using 10uF caps, the effect of the CV will be washed out to some extent. It will still have an effect but not as noticeably as on the faster versions.

Soundpaint 505 String Machine Walkthrough - The Secret Weapon of Vangelis

video upload by Soundpaint

"Grab the 505 String Machine here: https://soundpaint.com/products/505-e...

505 String Machine is the definitive ultra-deep sampled (UDS™) string machine. The most detailed sampling of the legendary RS-505 Paraphonic ever done.

The secret weapon of Vangelis. While the CS-80 became the icon, the RS-505 was the warmth underneath, equally present across his most celebrated work. Essential on records by The Police, Depeche Mode, The Cure, New Order, Jean-Michel Jarre, and Herbie Hancock. The string machine that shaped the sound of an entire era.

505 String Machine includes expertly crafted programs built from extensively UDS™ sampled parts, capturing every nuance of the original hardware’s divide-down oscillators and analog ensemble chorus. That constantly shifting, organic phase movement that makes the RS-505 impossible to replicate with synthesis is preserved in full detail. Expanded with our custom 505 C.A.F™ modeled filter for deeper sound design while staying true to its analog soul. The result is instant tone and deep creative flexibility.

Casio FZ-1 aliasing and loop cross-fading

video upload by Collector Current

"Changing the amount of loop crossfading has the side effect of changing the interpolation algorithm of the Casio FZ-1 sampler. Even when playing a non-looping sound.

At lower values, crossfading can sound like a stutter or an echo.
