ARP 2600 part3: Improvisation

part 2 here
"some fun with the mighty ARP 2600.

This one is modified to facilitate much more flexible PWM and extended keyboard functions. Rebuilt PSU, preamp and filter.

SORRY that the video drops off toward the end there....Windows MovieMaker is to blame for not being Quicktime friendly. Kodak is to blame for only shooting in Quicktime format on the Zi-8. And of course I am to blame for attempting to use them together (ooof !!)"

Electro Harmonix Sequencer Drum

YouTube via Zolophile |

"Super quick sound demo for the Electro Harmonix Sequencer, adjusting pitch, decay, and rate."

via this auction
"The Sequencer Drum is one of the rarest Electro Harmonix pedals. Unlike some of the other EH obscurities, this one is actually useful and sounds amazing! Not only is it an 8-step CV/Gate sequencer, but it has a built in synthesizer and a mode that allows you trigger the sequence at a set decay! The leather pad on the front is meant to be tapped to activate the trigger (hence the "drum" in the title). This particular sequencer is the fully patched out version, with an input that allows you to clock the unit externally, and CV and internal Clock outputs for sequencing other synthesizers."
