ARP Sequencer Model 1623

This is the 2nd of 2 versions of ARP Sequencer produced - it's got a smaller footprint than the later version, is lighter weight, and is made to match some of the later ARPs, though it will still look rather pretty next to earlier ARPs or synths by other brands. This analog sequencer was designed to be used with the ARP 2600 and Odyssey but will work with many other analog synths with CV and gate inputs. Instead of entering notes from a keyboard, this sequencer gives you knobs to tweak the pitch with your fingers - all you have to do is dial up the sequence you want, with no knowledge of notes necessary. Since this sequencer outputs voltages, as long as you have the right connections on your synth, you can use it to control other voltage controlled parameters - many old and now new analog synths have CV inputs for volume and filter frequency, which can also be controlled from this sequencer. ARP seq's are great for people who like to tweak until they come up with something interesting. It's a much more hands on and experimental approach to making music. This sequencer is the perfect tool for recreating that early electronic music vibe, is great for making new techno loops or experimental music. It's not just limited to these styles but is best suited to them. It's an excellent piece to interface with most modular synthesizers because it has patch points for everything.

-16 faders
-16 step or 8 x 2 (parallel) step mode
-sequential or RANDOM sequence mode switch
-GATE ASSIGN BUS! - each step can output a gate out 1 of 3 gate bus outs - this is great for sending gates to different synths or envelope generators at once.
-2 channels of voltage outputs - 1 for the first set of 8 faders and a 2nd for the other set. This way, you can use your first set for pitch and your 2nd for filter cutoff, for example.
-2 quantizers! Unlike most analog sequencers, this one quantizes its outputs so that it will easily play stepped pitches -it's much easier sequencing 12 tone melodic parts when you don't have to fine tune every step but at the same time, the quantized outs on this sequencer have a much narrower pitch range than the other outs. Note: we calibrate our ARP sequencers to output 1 volt per octave. If your synths oscillators are not set to respond to 1 volt per octave, either due to design or due to being out of calibration, the quantized outs might not sound in tune. The main CV outs will work fine in this case, though you should really have your synth serviced if it's supposed to be 1 volt per octave.
-skip/off/reset switch, button, with input for external control
-step button with jack
-position 1 out jack
-clocked gate 1 out
-start jack, stop jack, stop.start jack, trig/gate switch, start/stop button, footswitch out
-clock frequency fader and FM fader with CV input - very cool for modulating clock speed!
-pulse width fader with PWM (width modulation) in jack
-clock out with LED
-quantized outs a and b
-cv input
-input a and b
-sequencer outputs (not quantized)
-multiple jacks (4)

This is a really fun piece of equipment that's more inspiring to us than most modern day sequencers. It makes a great addition to any analog synth studio / collection. Remember, you dont have to have an ARP synth to use this piece.
