"The Moog Source is a monophonic Z80 microprocessor-controlled analog synthesizer manufactured from 1981 to 1985. Serial number: 2840

The Source was Moog's first synthesizer to offer patch memory storage. The design was also the first (and only) Moog synthesizer to feature a flat-panel membrane keyboard to replace the standard buttons, knobs and sliders, along with multihued panel graphics that were very different from anything Moog offered at the time.

Arguably the closest sounding to the Minimoog than any other Moog from this era. All functions tested in great working order, membrane buttons operate as expected with smooth operation.

Service notes:

-Refurbished power supply: replaced PS caps

-Resoldered rectifiers and sockets for t0-220 package voltage regulators

-Resoldered and cleaned connectors/pin headers.

-Replaced all other remaining electrolytic capacitors

-Replaced (2) connectors pcb and cable side

-Resoldered and cleaned all connectors/pin headers

-Cleaned keybed assembly and key contacts

-Removed and cleaned IC pins on 74373 logic ICs

-Cleaned all calibration trim pots

-Replaced memory battery

-Re-programmed all original factory presets

-Fully calibrated entire synth

-Burn in for 6 hours then checked/adjusted calibration as needed

-Cleaned volume control and bend/modulation assembly parts"

"This Andromeda is actually in very good condition and all voices function and tune perfectly, but the Potentiometer #4 for PAN near the screen needs replacement as it is very jumpy so it changes the Pan parameter,and a few other pots are pretty fiddly as well and could do with servicing."

Terry Riley's In the Summer (Buchla Music Easel)


video upload by Electrum Modular

"I’ve been reading Trevor Pinch and Frank Trocco’s excellent book, Analog Days. Apparently, when Don Buchla unveiled his prototype Buchla Box at the San Francisco Tape Music Center in 1965, the most enthusiastic witness was Terry Riley, the pioneer of minimalist music. 'I think I’ll do some music on that,' Riley said.

Sadly, there’s no recording or other evidence of Riley playing the Buchla (at least that I can find). But given that they crossed paths at the Tape Music Center, I thought it would be appropriate to use the Buchla Music Easel to do a cover of one of my favorite Riley pieces: “In the Summer” (1974).

Composed for the soundtrack of art-house film, Lifespan, this piece was reissued in 2007 on the CD, 'Les Yeux Fermés & Lifespan.'

Listen to the original: [below]
