Casio SK-1 Ciruit Bent

“Very versatile well built and bent vintage Casio
. Great for experimental or electronic music. You can get a lot of different patterns & glitches from the patch bay ..If you have never used one fear! the simple explanation is use a banana cable and patch. Go for it no wrong way . I’ll throw in a couple cables to get you going.

To use this synth you will need banana cables ,and a Boss style 9v power supply.The builder pulled the speaker and added a 20 point banana plug patchbay. 1/4″ output jack And 9v input .

As you patch the points together it glitches out Sending the SK-1 OFF COURSE .Without patching it will work as a stock SK-1. Not so pretty but it really is a unique monster ! The reset button does not work so well so I just shut it off if reset is needed. ” Click here to visit listing on eBay

Circuit Bent Casio SK-1

“This Bent Casio is the most AWESOME Glitched Sampler/Keyboard I have owned. It was modified by that Master of Bending, Sam Peck. Sam has custom-made several Bent Devices for me but this one was from his own personal collection. It has SO many possibilities I have only just begun to tap it’s potential. For instance rather than have a somewhat limited Patch Cord Bay with a half-dozen patch cords, this Bending Matrix has no less than 29 THREE-POSITION TOGGLE SWITCHES!!! Plus 3 more Three-Position Toggles on the end of the Keyboard. Making a total of 32 Toggles!! It also has a very cool Pitch-Bend knob. And get this, IT IS ALSO MIDI-CAPABLE!! YOU CAN PLUG ANY MIDI-COMPLIANT INSTRUMENT INTO IT AS A CONTROLLER!! I have used this function many times, plugging this SK-1 into my KORG Karma Workstation and using it as a sound source. I haven’t seen many Bent Boards that can do that.

Like all Bent instruments it can be temperamental, a quality I’ve actually come to love. You never know what weird sound it’s going to throw at you on it’s own. The random Zen Element . . .this is something I really value as an assembler of weird, spontaneous sound events.

This Bent Casio SK-1 is a hardy little board that has been handled with TLC. Never Toured. Lives in my smoke-free home studio. I’m only selling it because I’m raising money for my Solo Blues Tour. That, and I know I can have Sam build me something similar in the future. Don’t miss out on this unique instrument!

It comes with an Universal AC Adapter (110) and also runs on 5 AA Batteries.” Click here to visit listing on eBay

” Selling a Casio SK1 sampling keyboard.Keyboard has a few marks as you would expect for its age but the battery cover is present and it all works as it should including buttons and keys. No crackly sliders and speakers work a treat.

This keyboard not only is a gritty sampler but allows simple synthesis along with onboard sounds and rhythms. You can process samples using effects as well as putting an ADSR envelop over it. It really is an underrated keyboard that with outboard effects can produce really good dirty sounds.” Click here to visit listing on eBay

(I don’t know if I was doing it right or if it was broken)But everything else is good and works. All input and output work. Comes with official Casio AC adapter.”

sk1 ” Circuit-bent Casio SK-1 built by

Keyboard functions normally if all switches are off.

Create incredibly strange sounds and beats.

Separate LFO circuit animates the sounds and sampled sounds for modulation.

An opto cell allows for theremin type of pitch work and total chaos in other patches.

It has an LED with ON/OFF switch that pulses and adds a modulating envelope glitch.

In addition, it has 9 bend switches that add strange modulations, algorithmic brain wave oscillations, insect emulations, whacked out drum beats, chaotic bass, syncopated rhythms, flanging, echoing, looping, the effects go on and on for incredible combinations only limited by your imagination.

A control knob on the front that allows you to dial out the drums.

It also comes with an ATARI joystick port and joystick that renders INCREDIBLE effects in each direction the joystick is moved as well as the button.

Also, there’s a pitch control knob with switch that allows you to choose between the original clock or a precission oscillator . This pitch knob greatly effects pitch several octaves.

There is a soft reset button and a balanced 1/4″ output jack.

Also included is a removable RCA patchbay module that plugs into the Atari jack when the joystick isn’t plugged in.

The onboard speaker is intact so you can use it on the go or anywhere you’d rather not drag your amplifier, a huge convenience factor.

*****I’m also throwing in a free optical theremin (shown mounted in beer can)*****” Click here to visit listing on eBay

sk-1” For sale is Casio SK-1 sampler/synthesizer. If you are browsing this auction then you know what a great little keyboard this is. This unit has a small broken plastic tine which makes one key stick up, due to being pushed up by it’s spring – the fix is not difficult, with a little model glue and scrap of plastic. Otherwise the unit is in very good condition for its age, and functions perfectly. This was my “backup” unit since I played the SK-1 as my main keyboard in one of my bands – my “main”unit has never failed, so I’m letting the backup go to someone who will enjoy playing it! Ask any questions you wish – comes with a photocopy of the manual; runs on batteries or a generic wall wart PS (neither included).” Click here to visit listing on eBay
