It is very rare when the loss of one man is felt by millions of people. Yesterday, one of my mentors --and indeed the inspiration of an entire generation of hobbyists and professional musicians alike--passed away only 4 months after finding out he had an aggressive brain tumor ( Read more... )

Insofar as I update at best yearly, it might stand to reason that my projects move about as equally fast. However, since I now have a dedicated room for my electronic music studio, I've been able to get it organized. A mere 17 months after receiving my modular cabinet kit, the thing is now sanded, sealed, sanded again, sealed again, assembled, ( Read more... )

I am not one often given to fancy or romantic thought (except perhaps when writing), but May 14, 2004 would have been my sister's 30th birthday. I wonder what she would have wanted...

Wow, over a year between updates. I use this as a bulletin board for old synthesizer repairs, but ever since quitting my day job to run my own business I'm busier than ever and things like LJ fall by the wayside. AH well, I will have more repair notices soon.

Completed Stephen Mattern's KLM-367 repair.

Todd Ruffins' KLM-367 repair 90% completed.

Started the overhaul of Crow's own rev3.3 Prophet-5 w/MIDI.

Repairs to Bob Hoffa's KLM-367 circuit board now completed.
Next up: KLM-367 repair for Steve Mattern.

For Bob: OK, the VCA mode (EG/gated), LFO->VCA destination select and VCO sub-osc select now work properly. Remaining are the VCO waveform select (only selects sawtooth, pulse/PWM do not work yet) and something flaky in the patch memory address latch chips. Hope to have these fixed later this evening.

For Bob: *almost* there. I have all controls working except for VCO waveform select (only selects sawtooth), subosc "-oct2" select, and LFO destination "VCA" select. I had to replace the patch memory chip.

1) Completed SCI Prophet-5 restoration for Ryan Day
2) Completed KLM-367 repair for Kelsy Presl
3) Bob Hoffa's KLM-367 has one problem remaining to find (front panel controls only work "halfway", which is a KLM-367 issue). Found this during the 48hr. burn-in.

..the birth of I and my wife's first child! I'll be back to board repairs as soon as Maria is home from the hospital.
