Don Martin era Moog modules

There don't seem to be any photos of the Don Martin era Moog modules so I posted some pictures at my site below. NO, THEY'RE NOT FOR SALE!


The construction is surprisingly good. Circuit board artwork and component layout is similar to RA Moog modules. Where Don really screwed up was the truly abysmal power supply with so much ripple that the oscillators would sync even when tuned to fifths or better. Unfortunately I didn't have these back in 2002 when Peake and Konkuro and I A/Bed original RA Moog with synth.com stuff.

Below is a list of modules Don Martin / Moog Music claimed to be manufacturing. I have not personally seen all of these modules so cannot speculate if all were manufactured. I have (1) 9501, (1) 9501A, (2) 9501B, (2) 9502, (1) 9503A, (1) 9504A, (1) 9505, (1) 9510, (2) 9511, (2) 9800R, and (1) blank panel. I think the original modules released were limited to those available for copying from Ohio University's system, which I should mention was never returned.

Back from AHMW 2007

Just got back from Analogue Heaven Midwest 2007 in lovely Lagrange Indiana. Thanks to Andrew for hosting and organizing. Pictures here:


I've posted some videos to youtube:


I have some audio from the event on DAT but I'll probably never get around to dumping it into a computer and editing.

Blacet Miniwave and Serge fun

And just to prove that my Serge isn't sitting in the corner collecting dust:


Below is a description of the patch. It's using about 1/100th the
capability of the Serge.

A ramp wave is created by a Serge PCO and is DC mixed with the output of a quadrature oscillator. The resulting wave is amplitude modulated by the 90 degree output of the above quadrature oscillator and feeds the input of a Blacet Miniwave. The Miniwave's wave input is modulated by a dual universal slope generator. The audio output of the Miniwave goes into an audio mixer and then into the variable bandpass filter. The audio is taken from the lowpass output while the bandpass output feeds back into the audio mixer in front of the VCF2. The bandpass output is mirrored into a detector and comparator and triggers an extended ADSR which modulates the bandwidth of the filter. Another DUSG modulates the cutoff frequency of the filter.
