Sequential Circuits Pro-One for John

video upload by foleytronics fx repair

Roland Jupiter-8 for Tyler

video upload by foleytronics fx repair

"Here is a demo of the Roland Jupiter-8 with a CR-78 and SRE-555 chorus echo. This JP8 had an interesting problem that many units with Encore MIDI have: an annoying click sound when moving any of the programmable sliders. It has since been solved and repaired and sounds lovely as ever!"

Arp Quadra for Randy

Norman McLaren's hand-drawn sounds

video upload by Robotussin Vintage Synths

"Scottish-Canadian animator Norman McLaren developed a technique of painting onto the optical soundtrack area of the film negatives of his animations.

The shapes would then make drones and buzzes when played through a special type of projector. He used the technique to create experimental soundtracks to his animations.

It's similar to Daphne Oram's technique of turning shapes into sound – though hers, which she called Oramics, was more complex, with dedicated machines that read shapes on the entire area of the 35mm film, rather than just the little strip that contains the soundtrack.

You can see the results in the third video above, an extract from McLaren's film 'Dots', which employs the technique.

McLaren – born in Scotland in 1914 – worked for the British Post Office's film unit until around 1939, when he moved to New York, then to Canada in 1941, where he produced animations for the National Film Board, before setting up an animation studio at the École des beaux-arts de Montréal and the Ontario College of Art.

There he produced around 70 films, much of it highly experimental and strange. He died in 1987 aged 72."

This also reminds me of the Optigan.

Norman McLaren is mentioned in this book: Vector Synthesis: a Media Archaeological Investigation into Sound-Modulated Light

Lunchbox Voice Prototype gets patched ! - Low-Gain Electronics | 4U Modular

video upload by LowGainElectronics

"Had a shop visit from the talented @helenastndc all the way from Spain/Sweden yesterday! We had a great discussion about synthesizers, design/diy and education. She got a little time to patch on the lunchbox voice system prototype on my test bench. We didn’t get a chance to get a proper recording of it but I fired it up where she left it and grabbed this recording of it this morning. Just turned a couple of knobs during the recording to see what sonic journey it would take! Hope you enjoy! Headphones recommend for full fidelity!"

Animated Tricillator Northern Light Modular Model 2AT Full Technical Overview

video upload by Kent

"The Covid Kid is back with his 90th video, 30 minutes in length(!), and 3rd round of Covid. I seem to only find time to make videos when I have some downtime due to Covid. Please excuse my flagging voice.

00:10 start of Audio Demos
07:39 start of Technical Overview and Features
08:07 AS3340 & AS3345 chips
08:20 What the 2AT isn't: not e-series and not based upon Buchla designs
09:38 The 4 main sections of the module
09:53 Common Control (Master Pitch in and offset knob)
10:33 Mix Out section with optical clipping
11:22 LFO Swarm based upon their Electric Dompteur h-seriers 1/2 space module. Genius!
13:35 LFO Swarm waveforms
14:15 the weird LFO shapes
15:05 8 octave range with rotary switch
16:08 mixer per oscillator
16:28 3 varieties of sub-octaves
17:39 FM normalling and routing
18:16 0-10V properly biased modulation outs on banana jacks
18:50 scoping out the modulation outs
19:50 shorting bars
20:00 listening to the various forms of oscillator sync
23:30 FM showcase. How it sounds and how the routing works.
28:00 3 Operator FM with 223e arpeggiator
29:21 Adding clocked LFOs and VCA mixing
30:14 fini!

The 2AT is an incredibly feature rich module:
It tracks over 8 octaves
3 oscillators with four waveforms each. Each waveform has an individual mix level control via knob and banana jack
Rotary switch for selecting the octaves
3-stage sub oscillator
Selectable Waveforum Mod CV (0-10V) out
Scalable FM and CV control
Full PWM control
Attenuverters wisely employed where they make sense
FM inputs normalled to the outputs of anther oscillator and the routing can be changed on the back
Sync I/O via shorting bars
Each oscillator's waveform outputs are mixed internally and are present at the MIX OUT if no single out is used
Optical clipping stages are present at each OSC, and again at the Mix Out stage

Clocked or Free-Running Swarm LFO
The 8 frequencies (the 8 outputs) can be offset in phase or frequency, always based on the master frequency.
It can go down to 0 Hz and freeze the levels at their present state
Each output has its own attenuator

Kodamo MASK1 // Proudly Digital & Uniquely Powerful

video upload by Jorb

"After my time with it, and the sort of reflection I get to find while editing, I think the strongest appeal of this synthesizer is finding identifiably digital sounds without any of the complex workflow of FM or wavetables, with just enough options past the oscillator shapes to feel like its not a 'dishonest' approach to those sounds.

You can find characteristically digital sounds, with the rest of the architecture being familiar / subtractive and it almost feels like I cheated my way to a modern man's PPG. Delightful.

HUGE THING that ended up cut, the manual is super good, really serious shoutout. Color prints, full pages, bound nicely, the whole thing. Love it.

Also I managed to also cut any take where I mentioned Roland's draw and chop oscillator options, which could be seen as a simplified bit masking. But rest assured I made the connection , don't comment like I didn't smh please

0:00 Intro
2:02 Hands on
4:25 Bitmasking Intro
8:23 Mid-demo Overview
10:01 Sound Design Begins
12:38 Play Modes
16:22 Splits / Layers
18:11 Randomized Patches (crazy good)
20:23 Drive-by FX demo
22:46 Low-key the best patch
22:54 Conclusions"

1969: What Is ELECTRONIC MUSIC? | Workshop | Radiophonic Workshop | BBC Archive

video upload by BBC Archive

Be sure to check out 3:59 on. I won't give it away, but it's interesting they had the same views back then. Note 7:33 for a glimpse of what would come. Finally also see this post for Daphne Oram's Oramics and her Bird of Parallax. See the Oramics label for more.

"What is electronic music? How is it produced?

Desmond Briscoe - the head of the BBC Radiophonic Workshop - enlists the help of Daphne Oram, David Cain and John Baker to explain the fundamentals of synthesised sound.

This clip is from Workshop: The Same Trade As Mozart, originally broadcast 3 August, 1969.

You have now entered the BBC Archive, a time machine that will transport you back to the golden age of tv to educate, entertain and enlighten you with classic tv clips from the BBC vaults."

Wavolver II demo

video upload by O.Z. Hall

Click here for additional Wavolver posts by O.Z. Hall.

"The Wavolver II is a waveshaper that includes both a wave (manual) folder and a pulse waveshaper (with vertical offset and pulse width modulation ). It also includes a second pulse wave. This Eurorack module is available from Elby Designs. The circuit was designed by Ian Fritz.

I'm modulating is with a quantizer which is acting as a kind of sample and hold circuit."

Digitakt Machines // OS 1.50 Upgrade

video upload by Elektron

"Machines. The Digitakt way.

As found in Octatrack, Model:Cycles or Syntakt, the concept of Machines has now also reached Digitakt.

There are now several new ways to play back your sweet samples. This new OS 1.50 Upgrade brings four different Machines, all with their own different flavor. Repitch for automatic classic beat-matching, Werp for a little quirky old-school way of time warping, and Slice - to chop up your audio and placing the pieces back in any order you like. And finally Oneshot, your default Machine for playing your sample forward, backward or looped. Again, again, and again.

To top things up we also added a new way to record your samples. You can now set a fixed number of steps for your recording. And, Sample Rate Reduction that can be inserted before or after the filter. Just as gritty as you like it to be.

Go find out more and download this new tasty OS 1.50 Upgrade here:"

Digitakt OS 1.50 Upgrade Overview

"As found in Octatrack, Model:Cycles or Syntakt, the concept of Machines has now also reached Digitakt. In this tutorial, we explore the four Machines - Oneshot, Werp, Repitch, and Slice - that come with the OS 1.50 Upgrade.

We also cover some creative tools that allow you to push Digitakt’s sequencer and samples further. For example, using Trigless Trigs to parameter lock values without re-triggering samples, using random locks in Slice to get new rhythmic ideas, or using Werp to really pull apart samples and turn them into completely new elements."

NEW MACHINES! Digitakt Ginormous update OS 1.50

video upload by Dave Mech

"Another massive update for Digitakt. This time we get 3 new machine types, sample rate reduction, recording length setting and a couple of small yet useful improvements! In this video I go over the major new functions in detail. Enjoy!

PS: After I created this video a small change was made to the OS. On the sampling page the recording length setting is now situated on the right and the AUTO setting shown in this video is renamed to MAX."
