I am cleaning out my Frankensynth modular to concentrate on my newer instruments so this gem is up for grabs: This is a single prototype module built by John Blacet (www.blacet.com) back in the 1970s. One of one and very rare. There was no documentation but this appears to be his original Digital Pattern Generator. I bought this from John himself a few years ago. I have used this on everything from Doepfer to Wiard modules and an Arp 2600. It is one of the most interesting CV controlled units I've seen. According to the original Synapse magazine article on John's site: "The Digital Pattern Sequencer is a Voltage source capable of producing up to fourteen step sequences. This is accomplished with four level controls, each operating in a separate time division, by multiples of two from each other. This enables the device to produce patterns whose steps do not necessarily have the same duration. When connected to a VCO, the results are quite rhythmical. The DPG can be gated, triggered, and run up or down by external control. In addition the pattern can be made to alternate direction on successive triggers" The full article including schematic is up at: http://www.blacet.com/dpg1.jpg and http://www.blacet.com/dpg2.jpg A picture of the actual unit I have is up at: http://helpwantedproductions.com/eh/blacet1.jpg (other pics available on request) In my picture you can see the four adjustable knobs each with an LED and toggle on the right side. There is a center toggle which appears to be a run/off/reset switch, one master knob, two toggles labeled u/d and g, and a jack labeled E.O.C. On the bottom are 1/8" metal input jacks labeled: Clock Up/Down Trig Out Out G Because I got this unit with a bunch of working and non-working units I do not 100% know everything about it. I do know I wired it up to a MOTM PS and have used it by externally running a clock into the "clock" input. All the LEDS and knobs did something, the toggle did the start/stop/reset thing. In short it worked and was pretty damn amazing. However due to it's age and rarity I am selling this AS IS. I ran it through it's paces just this morning again and everything worked as well as it ever has but again I'm not a tech nor do I know fully WHAT each part is supposed to do. I will include the MOTM PS connector I used to run it from a MOTM PS. This unit influenced John's current Binary Zone module so you can go look that up which might give you more of a clue. However the two ARE different. Needless to say this is one outrageously rare and collectible piece. More importantly it is one VERY cool and unique and usable piece. I am not looking for KKKollector cash and would prefer to sell it fast and to a good home, hence this post to AH first. I can only imagine the horror of selling something this rare on Eb*y with the idiots and ignorance that goes there. "Buy-it-now" here please, LOL! I am asking $150 plus shipping which it certainly is VERY worth but I am open to SERIOUS offers. I will answer any questions. I WILL sell it to the first person to offer to buy it confirmed via phone so please send your phone # to speed things up if you are interested. A simple "I'll take it" won't secure this sale. I can accept Paypal via bank transfer or prepay USPS MO. References out the wazoo. I will pack extremely well for free. On a final note I HIGHLY recommend poking around at John's site and buying from his new line of modules (which are compatible with this BTW). He is an amazing and very creative inventor and yes, I do own many of his other designs and no they are not for sale :) Http://www.blacet.com Thanks!
