Casio Sk-1 Atari 2600 circuit bending project

via Chad Burger on perthband.com where you will find more info and shots.

"I have modded a casio sk-1 keyboard with a circuit bent patch bay which is linked to the switches on the atari part of the controls. The two silver dials control a pitch bend and a poly voice filter bend. I also installed a 1/4" guitar jack out and a red reset button as sometimes the bends cause the sk-1 so freak-out and freeze requiring a deep reset."

From what I can tell, only the controls of the 2600 are used.

Custom MacBeth M5N "Blue Meanie" / "Blue Marvin"

via Ken MacBeth:

"Hi Matrix! ...well to continue with the custom panel thread- a prolific german client asked to have 2 M5N synths built for him- but with a special blue color that I ordered in- this color was swatched against the color type of the very first ARP 2600s. We discussed whether or not they originals were called 'blue meanies' or 'blue marvins' - maybe the viewers of the matrix synth blog know this stuff! I am currently offering direct sales of two Process Red M5Ns (...there will be a fire in the disco!) that go as a pair-both hand built by myself, and not the factory I'm using- there is a premium for this- but interested parties can enquire- pics to follow soon. Best To All- Ken Mac."

Via this post: "The very first model 2600 was produced in early 1971 and is known as The Blue Marvin. It has mistakenly been called the "Blue Meanie" but according to Alan R. Pearlman, the Blue Marvin is so named after Marvin Cohen, head of engineering at ARP at the time."

"Here is the new Jomox T-Resonator processor. Mike has the Casio VL-Tone and a drum loop running into the T-Resonator which really screws up the sound in a very interesting way."

i'ts very hard to find even in Japan nowadays difinitely synthesizer collectors dream! [are Japanese synths easier to find in Japan? :) Never really thought about it until now]

cute! very small and light weight analog synthesizer it has full sized 32keys 1VCO, noise,VCF(resonance self-oscillating),ADSR,LFO,and each various controls VCO is free scale(not change by octave range)like modular synth simple architecture but very easy to use and can creates versatile sounds fat analog bass sound to warm leads,retro SFX sounds etc good synth for both recording and live performance(small and light weight and looks cute)"

Update via museslave via the comments: "Automatic Gainsay has a video demo of this keyboard on YouTube." Indeed he does, you can see it here. Note the one up for auction is not the same as the one in the video - at least I think so. :)
