kNoB technology Dragon-FLY Stereo Frequency Scanner and Vca Eurorack Filter Demonstration


kNoB Technology

"Demonstration of our new eurorack module. Only raw sound.
Input signals random sequence and saw vco.
Voltage controlled stereo frequency scanner Dragon-FLY fully analog
I wanted to create a flexible and powerful tool,
which can mix a large number of signals and process them.
Inside:
- two multi-mode diode based Sallen-Key 12db/oct filters with constantly available inputs of different types of cut and input attenuators
- two classic ota VCA with lin and log characteristics
- voltage can control the cutoff frequency, resonance level, VCA gain, pan
- both filters can be controlled by one knob with different modes

Time sections:
00:00 Hello and Block structure
00:11 Lowpass test
04:10 Highpass test
07:13 Bandpass test
10:07 Allpass test
13:32 Frequency scanner test (different types of signals)
17:40 Frequency scanner test (drone sounds of different frequencies)

POLYEND TRACKER


100 Things I Do

"Its been a little while since I released a clip, I've been working to complete my next release SP*CE and getting the next big project under way. In-between my Polyend Tracker arrived last week and I have been slowly learning the workflow! I'm seriously impressed in the quality of this unit! More to come in the near future..."

Radikal Technologies Spectralis 2 monosynth and Elektron Machinedrum


MIDERA

"In this video (very long and just lots of arpeggiation), I am just messing with the monosynth engine in the Spectralis. Here is how it's set up:

All oscillators (4) are going through the 12 db multimode filter (set to HP), then that goes into the 24 db lowpass filter. Somewhere in the video, I end up routing the LP filter into the Fixed Filterbank and start messing around with that, so the output is actually the LP filter AND the FF.

The Machinedrum is just doing a simple beat (obviously).

The Spectralis monosynth engine has Eventide Blackhole on it and has its own internal delay FX that I use late in the video."

PPG Waveterm A / B


via this auction

"For your consideration a a very rare PPG Waveterm. This is a Waveterm A that has been modified to Waveterm B. With the right boot disc, you can also get it to load A.
The Boot discs that I currently have seem to be compromised, and won't load, so it has not been tested further than powering on.
The unit recently had the power supply rebuilt, and the display was serviced, and is steady. Currently running on 120V. All that is included in the listing is the PPG Waveterm as pictured. Due to it being untested, it is being sold AS-IS."

5 Voice Polyphonic Moog Phatty Calibration Analog Synthesizer Rik Marston


Rik Marston Official

Calibration test for all 5 Phattys! It's nickname is "5moogy" ;)
Very interesting to hear the different cycles overlap, almost harmonic!
The Purple Moog Little Phatty now has 4 Slim Phatty friends!
5 Voice Polyphonic Moog Phatty System, it's super sweet!
So cool to play a real polyphonic Moog! Pure HEAVEN!
No FX just pure analog signal to Mackie mixer then the BR-600.

Studio.H CSR CV Demo


Todd Barton

"A little unfolding of the CV routing section for the Control And Signal Router by Doug Clauder at http://studiohsoftware.com

Though it has kinship to the Buchla 210e there are so many more features and, for my mind, a more friendly and intuitive interface.

And big thanks to my Patreon family for their continued support of these video demos and tutorials https://www.patreon.com/synthtodd"

Синтезатор АНС / ANS Synthesizer (1960)


Dmitry Bystrov

Excerpt from the newsreel "Наука и техника" 1960 №12 https://www.net-film.ru/film-75521
Синтезатор «АНС» — фотоэлектронный оптический музыкальный инструмент, сконструированный советским инженером Евгением Мурзиным, один из первых в мире многоголосных музыкальных синтезаторов. Рабочая модель АНСа была закончена в 1958 году, в 1959 Мурзин получил на своё изобретение авторское свидетельство. Он обозначил синтезатор аббревиатурой «АНС» — в честь композитора Александра Николаевича Скрябина.
The ANS synthesizer is a photoelectronic optical musical instrument designed by the Soviet engineer Yevgeny Murzin, one of the world's first polyphonic musical synthesizers. The working model of ANS was completed in 1958, in 1959 Murzin received an inventor's certificate for his invention. He designated the synthesizer with the abbreviation "ANS" - in honor of the composer Alexander Nikolayevich Scriabin.

Jam with Polyend Poly2 and DIY Analog Modular-System


Andreas Remshagen

"I broke my rules and connected my DIY-Analog-Modular System
with the Digital world. I bought a Polyend Poly-2 Midi to Multiple Gate/CV
converter and experimented with different ways driving my Modular-System.
Each Midi-Channel can drive one Synth in its Gate and CV so i could program
a polyphonic example including different analog-Drums, analog groove-Synths,
a String-Synth and a Bass-Synth. I took my old Asus Eee-PC and worked with
the good old Voyetra-Dos Sequencer in a DOS-Box under Windows7 32bit
(DOS only wouldnt work with the Polyend over USB)"

1979 MTI Auto Orchestra AO-1 Analog Synthesizer / Drum Machine



via this auction

"The unit is fully functional and works as it should.

This is the very rare MTI Auto Orchestra AO-1 drum machine / bass synth / strings / chords accompaniment unit + bass pedals and cover for the front of the box.

This thing is pretty insane. The Drum machine sound is off the hook!

The MTI AO-1 has many different drum presets and each preset button has 2 variations. Each drum voice has its own cancel button (!) so you can choose whatever elements of the beat you want (say just kick drum, kick + snare, cancel the cymbal, cancel conga, etc.) so the combinations are pretty much endless.

Very powerful bass sound. reminiscent of the TB 303. Strings section and chords section.

When no drum preset is chosen, you can play the bass and strings manually using the pedals. When a preset is chosen, the pedals will determine the chord.

The volume knobs of the different sections can be pulled for constant signal. When these knobs are pulled, they control the volume for its assigned section."

Stylophone Gen X-1 : A true small and fun synthesizer


SynthedMind

"The new stylophone Gen X-1 is like the old and original, but with lots of new and great features.
The original sound can also be achieved by setting all controls to OFF position.
But when you start rotating or switching these, a new sonic world opens !
It's a handy small and affordable little synthesizer and has following features :
- Attack - Decay controls : these set the rise and fall of the pitch or filter cutoff.
- LFO : this is a low frequency oscillator to modulate the pitch of the tone. You can select between square or triangle. The speed and modulation depth can be set.
- Delay effect : this is an effect to "echo" the sound output. You can control delay time, repeat time and balance between dry or effect.
- Low pass filter with cutoff and resonance.
- Pulse width modulation : this creates more harmonics to the sound.
- 1-Octave and 2-Octave sub oscillators. These add depth and lower sounding notes.
These can be freely mixed with the Pulse width modulation.

- A very good build in amplifier and speaker which produce deep and warm sounds.
- It's handy and very compact. The stylus is a new way of playing music. You can slide over the notes.
- A ribbon controller : this can also be used for adding extra notes when playing with the stylus.

By tweaking the knobs many normal or strange sounds can be achieved, just like a real synthesizer.
I found a warm and synthed sound and demonstrate it in this video.
I also demonstrate the pulse width modulation and sub oscillators."

D501 VCF Demo (no talking)


DoveAudio

"A quick play around with some of the features of the Dove Audio D501 VCF which is based on the NJM2069 VCF/VCA chip.
Here the Q911 drives a moon modular quantizer into two WTFs set to sawtooths for the oscillators, fed into a mixer and into the D501.
The Q119 also clocks a quad AD/AR module (schematics in my blog) and the output of the D501 goes into the corsynth QuadVCA where a little is set to the FX capacitor with a delay before going into my desk.
No EQ and recorded straight into my ID14 and my PC.

Sorry for the blurry picture, I forgot to clean my camera lens"
