Shakmat Modular SUMDIF / playthrough / more than a mid side processor

video upload by BRiES

"In this video I take a closer look at the functionality of SUMDIF by Shakmat Modular. SUMDIF is only 2HP wide and can be used for a lot of things: inverter, averager, buffered multiple, precision adder, mid/side processor, ... .

Besides showing how you can create interesting modulation signals, I walk you through a patch to make supersaws with sumdif (and a comparator) as well. I also demonstrate and explain how mid/side processing works, how to use SUMDIF as a mult and a precision adder. I haven't recorded an example of using SUMDIF as an averager, but just know that it's possible using the A+B outputs (with the jumpers on the back added for a 6dB gain cut)."

Sbranvlztronics Low Frequency Oscillator Sync Test - Analog LFO with Reset on Breadboard

video upload by Unrelated Activities

"Testing a LFO with a synchronization circuit. The idea is to force the LFO triangle wave output to immediately go to zero volt when receiving a positive gate or trigger at a Sync input. When the gate or trigger at the Sync input returns to zero, the triangle wave output must then always restart with an upward ramp. On this breadboard the reset circuit was implemented with a CMOS analog switch, and the sync control is just a wire to activate it."

Therevox Ondes VCO eurorack module

"ONDES VCO

The Ondes VCO is a eurorack compatible re-creation of the original 7th generation Ondes Martenot oscillator with several improvements and additional synth-friendly features.

A RARE LEGEND RE-IMAGINED
The Ondes Martenot is one of the first electronic musical instruments, originally designed in 1928 by cellist and wartime radio telegrapher Maurice Martenot. In the 52 years that followed, the instrument was in continous development. By 1975 the vacuum tubes were replaced by solid state electronics allowing for many new and unique timbral combinations. We have revived these sounds from original schematics provided by and with guidance from Jean Landry, who was responsible for repairing many Ondes Martenot in Canada.

From the original discrete triangle core oscillator to the specialized wave shapers and mixing circuits, these sounds are now available for modular synthesis. The layout and function of each switch has been preserved to make this oscillator an ideal performance tool, and three independent switchable outputs can be used to patch unique destinations in the spirit of the Ondes Martenot's selectable Diffuseurs.

IMPROVED AND EXTENDED
Our Ondes VCO uses a temperature correcting pitch circuit, precision components, and also makes several improvements that increase stability over variations in voltage and temperature. For interfacing with the synth world, we have added a 1V/OCT pitch input, four position octave switch and three buffered outputs. We have also added two high-quality internal VCAs giving CV control over Octaviant (8) and Gambe (G) waveforms with illuminated level indication.

Silkscreened aluminum front panels are available in four different colours and combinations of industrial powder-coating and bead-blasted anodizing. All units go through final inspection and calibration by Therevox in Canada.

Rhythmic LFOs How-To w/ NSI Quad LFO + Expander + Babel

video upload by New Systems Instruments

"This video explains how to make rhythmic LFOs with your Eurorack modular system, using the Quad LFO, the Phase Expander, and Babel from New Systems Instruments. You can use these same principles to combine any modulation sources that give you control over the phase of the outputs, and with any maximum/minimum/analog logic module. But note that the behavior of exclusive some (XOR/balanced middle) is unique to Babel.

For more about these modules, see:

https://nsinstruments.com/modules/qlf...
https://nsinstruments.com/modules/bab...
https://nsinstruments.com/modules/HSO...

Module descriptions:

The Quad LFO is an 8 HP analog sine core oscillator, giving four independent sine wave outputs. Each of the outputs ranges from nearly stopped to about 23Hz, covering the full sub-audio range and just dipping into the low audible frequencies. Each has linear voltage control as well, meaning that an increase in control voltage gives a proportional increase in output frequency. While each LFO is initially configured as a sine wave, there are four jumpers on the back to switch between sine and pulse wave outputs. This can be handy for using one of the four LFOs as a clock, or if you just want a square wave LFO for some other reason.

The 6 HP associated expander gives you three more LFO outputs, in a controlled phase relationship with the LFO to which they are connected. That is, each of the outputs is delayed by a certain percentage of the LFO cycle. The first output ranges from 0–180º, or from unison to a half cycle delay. The second ranges from 90–270º, or from a quarter cycle to three quarter cycle delay. And the last ranges from 180–360º, or from a half cycle to a full cycle delay. The phase expander can be useful for creating interesting rhythmic modulations, or when the LFO is configured as a square wave, giving you three phases of a sine wave LFO synced to a clock."

Spectralis Walkthrough Part 1 - Navigate oscillator routing and some basic sequencing

video upload by MIDERA

"I haven't made a Spectralis walkthrough or tutorial in a long time so I tried to make a more in-depth walkthrough of the Spectralis I and II oscillator routing and structure. Hopefully this is something you can go along with and learn some things as I walk through this. I realize I fumble around quite a bit, but some of the things in the Spectralis I just never use so I haven't put much effort into learning. Please set your bar low for quality of my video - I'm not loopop and don't have the time to produce better videos. Sorry for that.

Where I think this will help is for someone wanting to learn how to route the digital VCO's into different filters.

I go through the basic overview of the Spectralis, then demonstrate activating the oscillators, how to route them, how to modulate them, and how to sequence them. At the end, I also go into routing external gear into the analog filters as well, although I wasn't intending to do that during this video.

My apologies for the video quality. I chose to use my iPhone to see how it would work and I was absolutely disappointed with how it turned out, from a shaky screen to low resolution to the inability to use the video without converting it first (and finding that conversion of the video slightly changed the speed of it too, making it difficult to sync with audio).

Hopefully you find this useful. But if not. That's ok too.
