ARP Sequencer with Original Manuals

via this auction
"1613 model, serial number 50... This is probably the coolest and most versatile analog sequencer ever built. If you've never tried one, they're amazing. For instance there are at least 9 simultaneous outs available for patching. It clocks, steps and resets from nicely from the trigger out of analog drum machines such as a TR-808 or 909 in tight sync so that you can program the individual step rates. It will add a keyboard CV to the quantized outs so that you can run it as 2 independent 8 step arpeggiators. It will also run at audio rates, effectively becoming a voltage controlled oscillator with the sliders controlling the waveshape a la Ian Fritz and a VC pulsewidth. These features are all tested, working and awesome.

It's worth mentioning that the sequencer powers on with the clock running. I'm not sure if Arp designed them that way, but my model 1623 does it too, and this has no effect on the function of the sequencer, everything works as it should. This is a really awesome machine, that will make anyone searching for an analog sequencer very happy."
