the Fairysynth

"You find an old oil furnace tester in a pile of rusty scrap iron. And what could be more natural than to build a small synthesizer into the unit?

This is exactly what I am doing in this video. But to make things fit into the relatively small space I had to simplify the design considerably: Instead of a Voltage Controlled Oscillator I used an astable multivibrator and a row of resistors. Instead of a Voltage Controlled Amplifier I used a clipper. And the envelope generators are really simple ramp generators.
But still it is working. And even though it has some quirks and appear a bit experimental it can still be used for something........ I hope.

The music that comes with this video - before the demo - is something I made back in the year 2000 on the Yamaha HE-8 and Technics SX-C600 organs. I used a Rhytm Ace drum machine for the rhytm and this machine was sync'ed to a homemade phasing unit that modulated the sound from a Yamaha PSS-12. I used a Dynacord Echocord Mini for the echo and the recording was made on a pair of Beocord 2000 tape recorders."
