Chronology part 6 - on Bontempi Hit organ

YouTube via organfairy. via synthzoom.
"Chronology part 6 by J.M.Jarre. Most of it was played as a MIDI file using "Noteworthy Composer" for Windows. Bass arpeggio was played on Roland JX8P, strings and choir on Yamaha HE-8 organ, the rest was played on the computer's Yamaha XG soundcard - except the solo. The solo is supposed to be played on an accordeon. But since I don't own an accordeon I used the "green monster" instead. The "Bontempi Hit Organ" was made in the 70's and was actually quite common. It is a simplified accordeon with an electric pump instead of a bellow. However, it's not very good as it lacks the nessesary pressure to play fast. But what could I expect from something I got for 5 dkr. (0.8$) at a jumble sale..."

VCO synchronization made visible

YouTube via MusicMiK. Be sure to see the others here.
"Did you ever wonder, what really happens with VCO sync? Here you can see it.
I made this video during development of another VCO, my synchronization master is just a provisoric square oscillator, which produces a very unclean signal. Besides this i don't have the audio equipment in the lab to create a better audio on this :) But the main syncronization effect is visible and hearable.

Schematics might be released soon, after drawing and final check."

polyphonic "switch on time" with the M563

YouTube via moonmodular
"People asking: "What is SWITCH ON TIME"? at the M563 trigger sequencer.

With SOT you can define and optimize the width of your trigger/gate output signal.There are more creative possibilities: e.g. the SOT function manipulates the envelope generator times. Depending on its setting, it lets the synth-voice/patch sound different.

[The pitch is produced by a M560 (960clone) sequencer.]"
