Description | A classic sequencer of the 70's. This is not a synthesizer, but it was (for its time) a sophisticated 16-step sequencer (model 1601) 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. The sequencer may be used in a "8x2" mode so that outputs 1 through 8 (bank A) and 9 through 16 (bank B) sequence in parallel. The Outputs of banks A and B are pre-wired to a voltage quantizer which effectively "rounds off" the sequencers voltage to the nearest whole twelfth of a volt. This allows precise tuning since all ARP products are tuned to a 1 volt per octave standard (1/2 volt per semitone). A low frequency voltage controlled clock governs the stepping speed of the sequencer and can be started, stopped, gated, or sped up either manually or externally.
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.
