ARP Sequencer Model 1613

Video Story ARP 1613 sequencer can play a single track CV with 16 steps or pushing a lever, special 8 x 2 mode at 1V/Oct for dual control (eg. VCO and VCF) Each CV step can be set to a specific voltage note value of course but also a special voltage gate on 3 gate bus  1-2-3 (upper switch)  which can be also used as an EG .  
 The sequencer allows a step reset to position 1 or a skip voltage on a specific step. A classic sequencer of the '70s. This is not a synthesizer, it was (for its time) a sophisticated 16-step sequencer used to control other synths. You create your sequences with the sliders. Adjust the sliders to change pitch while each slider represents a sixteenth note, for example, in the 1 bar pattern it loops. It uses the ancient Control Voltage (CV) and Gate protocols to play your sequences on another analog synthesizer. Because of the various types of CV/Gate used by different makers at the time, the ARP Sequencer works perfectly with the ARP 2500, 2600, Odyssey, Avatar and other ARP synthesizers as well as Roland, Oberheim and Sequential Circuits. To interface the Sequencer with other types of CV/Gate capable synths would require a CV converter box. Once you get it working it's fun and easy to learn. Use it to create continuous arpeggios or simple sequences of patterns for your vintage analog gear. Tweak it in real-time as you create or perform, it's very hands-on. It has a classic and recognizable character as you can hear in the demo below. Famous users include The Who, Depeche Mode, 808 State, Vince Clarke, Jean-Michel Jarre, Billy Currie of Ultravox and Visage, and film-maker John Carpenter.
