Analogue Systems rs95 oscillator tracking demonstration

YouTube via bigcitymusic
"Here is a demo of the Analogue Systems rs95 analog oscillator played along with the rs370 digital oscillator (for reference). This test shows the amazing accuracy of the scaling on the rs95 oscillator."

Anyone know what synth that is? I thought it was a Yamaha S08, but the buttons and data wheel are different.

Update via Väinö in the comments: "Pretty sure it's a Yamaha S90, not the ES model but an older one: link"

How a VCO Works

Sequence 15 has a post up on how a VCO works. If you are interested, you can check it out here.

"So synth circuit designers, starting with Moog and Buchla in the early 1960s, long ago turned to "artificial" oscillator circuits that do not rely on natural resonance. Rather, they rely on an analog implementation of a mathematical function that can be made to increase and decrease proportionally to the control voltage. A second consideration is that a useful synth VCO is expected to output several different waveforms, so that the synth player has harmonic starting points for creating a given sound. Rather than create a separate VCO circuit for each desired waveform, it is far more cost-effective to design a VCO "core" that generates a waveform from which the other desired waveforms can be derived."

Modular Beats

"mangling some Machinedrumbeats with my Modularsystem, the bassdrum in the beginning is not from the Md - it's created my the Cwejman VCO and Adsr

te beat from the md runs through the Doepfer BBD , the Cwejman Resonator and the Doepfer Wasp Filter"

Devantech SP03 Text-to-Speech Synthesizer

YouTube via MarcusACU
"Here you can see (and hear) my SP03. The Sp03 is a small Text-to-Speech synthesizer. Normally the Sp03 uses only a little 0,4Watt speaker. I connected a bigger speaker through a external universal amp.

The text is:
"How are you? I am fine! My name is SP03. I was build by Devantech. You can send me a englisch text and my integrated speech synthesizer willl produce a voice. Can you understand me? I am very sorry, but I can speak only english."

Flame Triode With Gain And Intriguing Flame Phenomenon.

YouTube via nylesteiner.

The application of what is described begins at 1:34.

"More info is available at http://www.sparkbangbuzz.com

If a cathode is chemically treated with a common household chemical and put into an alcohol flame, electrons can flow to a positive anode that is placed inside of the flame. This creates a diode rectifier.

What is very intriguing though, is that electrons can still flow to the anode even when it is well outside of the flame.

A grid placed within this space between the flame and anode can control the amount of current flow. This creates a triode with gain with similarities to a vacuum tube triode."
