ARP 2600 with AM2140 EMu Resonant Filter

O.Z. Hall

"This video explores expanding the ARP 2600 with an addition multi-mode filter. This is similar to what one might do with an ARP 2500 with both the 24db/oct Low Pass filter as well as the 1047 Colin multi-mode filter. I hope you enjoy the video"

RIP Dennis Colin, Co-Designer of the ARP 2600 & the Aries Modular

Some sad news in via Grant of Music Technologies Group. It has come to his attention that Dennis Colin of ARP and Aires fame has passed away. There is a GoFundMe page set up to help his daughter with the funeral and travel costs. Click through for details.

Dennis Colin not only designed the ARP 2600 with Alan R. Pearlman, he also built the Aries Modular (see this post and this post for reference), and he later ran Colin Electronics.

The image to the left is from an article in Guitar World from this year, back on February 9. The following is a short excerpt:

"The short story goes like this: Dennis spent several years at the ARP company, creating the 2600 and other strange instruments. Eventually the company changed hands and he moved on to other work away from music.

Years after retiring, Dennis now lives alone in a small house somewhere in New England. He recently lost his wife and has been having a rough time. A chance meeting between his daughter and my guitar-building buddy, Ben "C.B. Gitty" Baker, led to my eventual visit to his house. I stood on his doorstep feeling like Ralphie about to meet Santa Claus.

A frail man at 71, Dennis has sharp mind of a teenager. Although he left ARP Synthesizers many years ago, he never left music and he enthusiastically showed me his secret lab upstairs in the house. There were oscilloscopes, strange strobe lights, a homemade 500-watt amp (!) and model airplanes scattered about. The dude lights his cigarettes from a Tesla coil! When he talked about music, he referenced everything from da Vinci to string theory.

Forget Ralphie...I was in the inner-sanctum of the musical Willie Wonka!"

A great man behind some great synths. He will be remembered. Be sure to see the GoFundMe page.

Update: Memorial Service to Be Held at the MIT Chapel on Friday, December 18th at 1PM.
