ARP Odyssey

images via this auction.

"Produced between 1974-76. The Odysseys I and II look and feel virtually the same. The main difference between them are the addition of CV/Gate control and a new black and gold color scheme. The 2810 introduced a beefier 4-pole VCF. This filter was similar to the Moog filter and did not last. While a persistent rumor that Moog sued ARP over this, no suit ever occurred. Arp and Moog came to an amicable agreement and a small licensing fee was paid by ARP for units previously manufactured. ARP soon after designed their own four-pole, low-pass filters. They came up with the 4075 filter which was used in subsequent Odyssey models. The similar 4072 was featured in the 2600, Omni, Axxe, Solus, and others. visit arpodyssey.com or vintagesynth.com for more details."

"The ARP Little Brother, produced from 1975 to 1977, is a keyboardless monophonic expander module, used with another ARP synthesizer. It has a single oscillator and LFO, controlled using other ARP synths to "fatten up" their sounds. It was commonly sold with the Axxe model, however could be used with any of ARP's synthesizers."

Audio Damage Vapor

click here for more info and samples on Analog Industries.

"As to what Vapor is, that probably requires a bit of explanation. What I need is a word that can describe the effect, since it's sort of a New Thing. Mentally, I use "psychosomatic frongulator," but obviously that sort of nonsense won't Increase Shareholder Value. It needs to be a word like "chorus" or something, a simple word that says what it does.

And what does it do? It has delay modulation, like a chorus, but it has diffusors, like a reverb. More or less. This is a semi-unstable network, and at extreme settings can make Intergalactic Robot Noises; it can also give a nice sheen to most any sound at more temperate settings, or knock the corners off pretty much anything. I'll put up some sound samples later today, but we're still touching up the code a bit, so these might not be 100% indicative of the finished product."

Modified Moog Prodigy

"This video shows my selfmodified Moog Prodigy Synthesizer. It is played by a little software step-sequencer (seq-303) on my windows-computer, together with a Doepfer MCV4 Midi-to-CV/Gate-Interface. One row of the sequencer controls the pitch, another row controls the cutoff-frequency of the filter. This little Moog is also shown in the german musicians-magazine "Keyboards" 09/2006. On the magazines added DVD you can find another audio-example and some samples I`ve recorded."
