Electric Druid Synth DIY Updates

via Tim on the SDIY list:

"There's a new page to describe a Moog 911 ADSR envelope generator clone that J-P Desrochers has done using my PIC code as a base. He's copied the exact logarithmic pot response of the original and done a front panel graphic. It's nice work.

I've also done a page comparing some CEM3320 filter designs that I found whilst looking into alternative circuits for my Pro-One. This includes the LPF, HPF, and BPF from the datasheet, as well as both filters from the Oberheim OB-Xa, and the Elka Synthex multimode filter. And the Pro-One's original filter, of course."

Roots Revival soundcheck and Rasta Dub Sirens

via this GetLoFi post on the somewhat fascinating use of "dub sirens" in reggae.
"Video of the system in action and an audio sample of the above device with just the noises. Whats interesting to note is that the Pitch is set via a rotary switch and not just a potentiometer. In a way that seems like it would be easier on the ears, no jumping around in frequencies. Another commercially available unit is from Theremin Planet for 130 Euros! I guess what I’m trying to say is that most of these Dub Sirens are simple dual 555 oscillators with a trigger button and Rasta colors."
