We deal in vintage synths, so we get to play a lot of fun toys. One of our favorites is the ARP 2600. We've sold many of them over the years, and each one sounds different. This is a video of 1 of a couple short "jam sessions" I had with the next 2600 we plan on putting up for sale. It's knobs are off as we were wrapping up cleaning and servicing this unit. We've got a keyboard for it but it wasn't used for this noisemaking session. ARP 2600s are well known for their filter instability. This one in particular is quite unstable - the filter clips really easily when the resonance is low, to the point where the sound can sometimes disappear, so it's great for distorted noises. Simply altering the volumes of the signals going into the filter and VCA can cause some very interesting rhythmic effects. Because of its unique sound, we decided to leave the filter the way it is rather than tweak it or replace it with a "better behaved" one. This video is a departure from my normal 10 second clips, so hopefully this won't bore you guys to death. :) Enjoy. Email us anytime at minime123@onebox.com"
