How paraphonic patching can add depth to your sound

video upload by Monotrail Tech Talk

"Simple ideas that can add depth and interest to compact modular voices are great! And today we tackle on of those ideas: Paraphonic patching. It’s a simple idea, but it opens up a series of fun experiments and patches that can create unique sounds and textures."

The ADDAC Random Bezier Waves

video upload by Monotrail Tech Talk

"Best day ever! I have been working on a module with the amazing people over at ADDAC, and it’s finally here! The Random Bezier Waves is an easy to use dual organic random voltage generator. Both waves have manual and CV control over frequency and output level. Curve and offset control, as well as three different clipping modes allow for a lot of different waves, from calm organic flowing voltages to chaotic jumping madness. The module produces 6 wave outs, and has two different gate outputs on top, making it great for patch-driving features and generative setups."

07:11 – Basic patches
16:46 – Advanced ideas
22:14 – Generative heart

"This module started with an idea from Rijnder Kamerbeek aka Monotrail, a straightforward random generator with interpolation between random points making it something like a complex, ever evolving, LFO

The concept is simple. It contains two identical smooth random voltage generators. Each has a frequency, level, offset and curve control. The frequency control sets a steady pace with which bipolar random voltages are generated. The level control works like an attenuator/VCA on the output, reaching from max output to closed. The offset allows shifting the whole wave up and down on the voltage range. Curve determines the shape of the interpolation.The bipolar activity on the main outputs as well as gate outputs are visualised with LEDs.

Both Frequency and Level controls have a CV input with attenuator. When there is nothing patched into the CV inputs, these are internally connected to the main output of the other channel. This normalization makes it very easy to add randomization to the frequency or level for more depth, or of course, add cross-modulation for chaotic voltages.

The output VCAs are usefull to dial in subtle and time-based modulation without the need for external VCAs. For example, to modulate the amount over time with an envelope, or use the other generator with slower speeds to add random changes to the level of a random voltage.

Both generators also have two other outputs. One is an exact inversion of the main output, so it responds to the level and CV input. This is great for stereo or inversed effect patches. The other is a simple pulse output, here there are two different behaviours, channel A outputs a pulse at every random generation, channel B acts like a comparator. Whenever the main is positive this comparator output is a high gate. And whenever the main output is negative or close to 0, there is no gate output. Great for random triggers or firing other events like envelopes.

A couple other outputs are also available and are obtained by averaging both channel main outputs. The first output is the average while the second is an inverted average."

Monotrail Tech Talk Eurorack Sound Design Sessions - Noise & Transients

Can NOISE make you sound better!? – Eurorack Sound design sessions

video upload by Monotrail Tech Talk

"Noise is a common ingredient in synthesis. But many stand alone synths have limited ways to use it. In this video I explore some ways to patch and use noise in modular patches. Not just the classic white noise. But also sampled and self made noise!

My sounds changed when I discovered transients! – Eurorack sound design ep2

video upload by Monotrail Tech Talk

"A transient - or the short start of a sound - has a lot of impact on how a sound is perceived. Yet a lot of synths and patches don’t explore transients very well. With a modular system, there are many ways to create and sculpt transients in detail, so in this video we take a closer look at some options!

A lot of control in a small package - The E4 endless encoder controller for DROID

video upload by Monotrail Tech Talk

"The people over at DROID have been busy and present a new controller for the DROID eco system. Today we have a quick look at the features, and some examples I have been testing out. I think the module is a great option when you are interested in starting with DROID with a compact setup. But it will add a whole lot of control to deep setups as well."

"Der Mann mit der Maschine | E4

The E4 is a controller with four rotary encoders.

The encoders look like normal potentiometers, but you can turn them endlessly in either direction. (Don't be fooled by the knobs, which do have a pointer).
This allows for a wide range of applications and great flexibility.

Each encoder is surrounded by a square of 32 multicolor LEDs. This LED ring is used to indicate the current value of the encoder. And it looks really great! The LEDs help you to give you an orientation by displaying the current value.

Each encoder contains a push button, which can be used just like those on the P2B8 or on the B32.

The E4 is perfect for mapping many different functions or presets to one encoder and then switch with the buttons of a P2B8 or B32 to some other context. Because of the LED rings you instantly see the current value after switching. And other than with pots, no "picking up" of the value is needed.
Furthermore, the nature of the encoders allows for some useful features, for example:

Create a "multi turn" pot, that needs to be turned several rounds for going through the total range (which allows for a finer selection).
Enable a mode where a slow movement of the encoder changes the value even slower, so it allows for instant fine tuning.
Use an encoder as a switch with a fixed number of positions (the LEDs visualise that)
Select a bipolar value with proper visualisation by the LEDs.
Use an encoder for "strumming", where you get triggers when it is turned.
As a bonus, there is a circuit called encoquencer, that allows you to build a melody sequencer based on the encoders and LEDs of the E4. It has the same features as the sequencer that is based on the motor faders of the M4 (motoquencer).
Power consumption:

+12V: 220 mA when all LEDs are white, 53 mA during normal use case
-12V: 0 mA
5V: 0 mA

Hint: The LEDs only shine fully white when you set them up to do so in your DROID patch. As long as you use the encoders in a normal way, the LEDs display colored light which is not as bright, so the power consumption is much less under normal circumstances."

DROID - Universal CV Processor

video uploads by Der Mann mit der Maschine

"This video introduces my new Eurorack synthesizer module "DROID". The DROID is a universal CV processor, that can do anything in your modular synth... except audio! The DROID has 8 CV inputs and 8 CV outputs and you can use them to implement lots of different utility functions, even at the same time. You can implement sequencers, quantizers, clock dividers and multipliers, trigger delays, precision adders, ADSR like envelope generators, random generators, turing machines, slew limiters, CV mixers, CV matrix mixers and many many more things."

The eurorack module that can do everything with CV – Introduction to Droid

video upload by Monotrail Tech Talk

"Droid – the Universal CV Processor – can basically do everything when it comes to control voltages. It can create modulation signals like complex LFOs and envelopes. Perform creative utilitarian functions like mixing, logic, quantizing, and so on. And it can do complex pattern and melodic sequencing. This gives you the power to create your own complex modules, or even entire custom control surfaces for performances.

I have been using it for a couple of months now, and in this video I explain how it works, and how it can be used. At least, I made a start, because the possibilities are basically endless!"
