"Good Old Casio sk-5. . . Been on a shelf for a couple of years, but still works OK. Gonna re-work some of the mods so thought I'd video this current incarnation first.

8-Bit Digital Sampling keyboard with too many mods to list.
A.M. style Distortion-Oscillator is pretty cool though & also has digital 'Synth-to-Drum' switch."

Circuit Bent Casio SK-1 with Data Bus Activity LEDs

Published on Jul 11, 2013 xerox-fish·48 videos

via this auction. Two additional videos below.

via the seller: "build quality

this SK-1 has been properly bent by me all the internal connections have been soldered with military precision and covered with heat shrink tubing. all the panel mount hardware has been tightened properly with locking washers and then glued in place from behind using hot glue for extra strength this unit has been built up to a standard and not down to a price. as always i have kept the speaker on this unit, used high quality switches and not messy patch bays and kept as many controls on the top of the unit as possible.

listing info
i will send a labeled image to show what all the switches and knobs do.
the unit will be sent in a strong box well packed with lots of bubble wrap.
PayPal or cash on collection preferred
any questions please message me
Features

27 switches
5 for stutter and time glitches and then when the group switch is flicked glitch root selection
1 for group selection
13 for general glitches
1 that holds sounds and loops them
1 for general distortion
1 for pitch knob bypass and turns the pitch knob into LFO amount
1 pitch LFO on off
3 for disabling the individual sounds in chord mode ie bass, drums, melody
1 battery saver / hard reset switch (saves just 2mA)

3 knobs
1 for stutter and glitch adjustments or when group B is selected glitch sweep
1 for pitch adjustments or pitch LFO depth
1 for pitch LFO speed
12 LED's

1 blue for the glitch sweep knob this can do everything from indicate the position of the knob to flash randomly
1 blue to display LFO speed and intensity
10 red that indicate activity on the ROM data bus they flash and fade some times sequentially some times randomly depending on what the unit is doing
misc
1 1/4 output jack that disables the internal speaker when connected
replaced corroded battery terminals
replaced power jack
the silver dots indicate switches that mess with the sampling input stage so sampling with these switches on will create interesting effects
personal niggles

if i had been a bit more careful installing switches a few small scratches could have been prevented
the hard reset switch is on the back i find this a little annoying but it was unavoidable due to the extreme lack of space.
the sound

the sound of this unit is the best i have ever heard it can create rich and long soundscapes with strange ambient background tones that sound something like the engine room of an alien spacecraft. the sample mangaling is Lo-fi and very meaty the glitch time is very adjustable and interesting alterations are created that can easily be re sampled for use in a DAW. the chord mode can sound very cool and glitch even creating some strange deep sub bass sounds the part solo switches are fun to play with as well."

Circuit Bent Casio SK-1 Sampler

via this auction
"circuit bent Casio SK-1 lo fi sampler and synth. This is the mother of all circuit bent keyboards! This custom unit has all of the standard features of the classic SK-1, with tons of extras. The added mods to this unit include sturdy modular case with unique stamped black vinyl, custom metal control panel with extra add ons, and internally mounted power transformer for 110v use. The added bends to this keyboard include 1/4" sampler input jacks for mic and line, 16 point RCA patchbay, an additional 5 patch points with potentiometer for variable effects, seperate 1/4" outputs for drums, bass, and main, high pass filters on the drum and bass outputs, pitch control knob, and hard reset button. There is plenty of space for adding additional mods or bends, such as extra switches or MIDI control...

he Circuit Bent SK-1 is a great keyboard for experimental and electronic musicians looking for a unique sound and sample source. The lo-fi 8-bit style beats, drones, and tones from this are quite impressive. This SK-1 is missing the C#/Db key above middle C. If you are looking for a normal keyboard this isn't for you. If you're after crazy and unique sounds, this may be your ticket! I have been selling my circuit bent creations here for over 5 years, and I take pride in offering unique, quality pieces. Sound samples of this and some of my other works can be heard at: myspace.com/anode8

Casio Christmas

via Kasio Kristmas on the forum

"Greetings everyone!

We just finished our experimental 10 track CD of classic Holiday tunes using only Casio instruments (mostly Casio keyboards, but we also used the Casio DH-100 Sax, DG-20 Guitar, and some Casio hand-held games). The recordings are mostly instrumental, but the few that do have vocals, we sampled our voices using the SK-1 & SK-5 or sang through the Casio VA-10 Vocoder, and Casio Rapman keyboards. This was an entirely fun and experimental project that we are very excited to have released. So far the respones has been great.

We hope that some of you here will have some time to check out what we have done with these old cheesy keyboards.
We have blended the nostalgic sounds of 1980's arcades, new wave, synth rock, modern electronica, chip tunes, ambient, atmospheric, disco, sountrack, jungle, & exotica all into one on this new Holiday CD. Even though limiting ourselveselves to only using Casio Instruments, extra care was taken to keep things interesting! It has many Audio layers and great production value . Isaiah Ikey Owens (The Mars Volta) plays a special appearance on the exotica honored track Mele Kalikimaka.

Thank you for your time and we hope to hear from you.

Modular Casio SK-5 Bent by Oceanus, the Vince Clarke Machine

YouTube via xd515
"Following on from the Modular Sk-1, this is a Mega bent SK-5 in a modular design, with a intergrated Speak and Spell called the 'Vince Clarke Machine'.. not endorsed by Vince but totally capable of making erasure'esque sounds!

Over 100 man hours went into putting this beast together and it has many technical bends previously unheard on the SK, such as the spacial distorter the Auto bend ( as on my modular SK-1 but now syncronised to the internal clock signals ) and the ability to re-program the percussion patterns.

Sadly I can't show all the features in the 10 minutes youtube allow, It can also separate and solo any one of the 4 channels, has separate Percussion / Speak outputs, will sync the autobend to the address bus, you can switch of the internal highpass filters etc.

The Intergrated Speak and Spell has it's own LFO and I have a similar one here on youtube.

This machine may also be for sale for a sensible offer.. :-)

Some hi-res pictures and sound clips can be downloaded from here" When you get there, click the more link in the description on the right and scroll.

Mego Muson Synthesizer toy art NEUTRA

via this auction

"Hi there. My name is Max Neutra. I am an artist in Los Angeles. Thanks for checking out the shop.

What we have here is a 10"x10" painting of a Mego Muson Synthesizer. In my opinion, this is the holy grail of vintage music toys. I was lucky enough to find one years ago before the ebay market seized up on these. You can physically rearrange the colored block in what I would call a sequencer, creating what the box says are "the strangest sounds in the galaxy".

This painting was originally created for a solo show / record release party in Hollywood. It sold, but in the end the buyer traded it back towards more expensive work. Now I offer it to you!

Before I started painting, I made electronic music for eight years. I was obsessed with obscure noise making devices and put together a hearty collection through ebay. Some of my pieces have even made it into the quintessential collection at miniorgan.com! I used these toys as well as other more professional devices to put together music that I considered funky electro ( Think Kraftwerk, Devo, Thomas Dolby, Yello, etc.). Suddenly painting took over about 5 years ago and the music making was put aside, but I recently made a final push and released my first album. Ten years in the making! The album is called Automation Addiction and can be purchased through itunes, amazon, beatport, etc.

Here is a list of equipment I used on the album:
Muson Synthesizer
Remco Sound fx machine
Bee Gees Rhythm Machine
General Electric Tote-a-tune
Texas Instruments Speak & Music
Mattel Electronic Connection
Panasonic r-1088
Tyco Hotkeyz
Waddingtons Compute-A-Tune
Science Fair Electronic Organ Kit

a few things i'd like to address that have been asked previously. regardless of who bent your instrument every bend on an sk-1 will most likely respond differently in different settings.. for example you will get different results in sample mode then in a preset.. and from one preset to another.. i have bent the instrument to be as stable as possible in all modes of the instruments.

the pitch and lfo is fine tuned. if a pitch is allowed to go too high it will glitch and will otherwise interrupt a good sound, loop, or bent function of the instrument. where this glitch occurs is different between sk-1's..the range therfore of the pitch control will sweep approximately up to 3 octaves down and approximately an octave or so above normal pitch of the note.

the right side of the instrument is the functional side of the instrument featuring mixing, reset and power indication... the casio is capable of 4 notes/sounds at a time along with drums.. the switches on this side allow you to mix on the fly or isolate certain sounds. this is especially useful when the instrument is locked in a particular bent function or loop and doesn't respond to key information. this way you can isolate a particular sound in the lock or loop and sample that particular sound or have only that sound running.

the patch bay is setup to be as stable as possible. these are not ins or outs to other devices.. they are meant to be patched within the patchbay only and will allow you to create new bends on your own.. since it's experimental it's not as stable for live use but great for studio work. with a little planning the patch bay can also be used in live use with good stability.. they will offer new bends not available on switches along with variations to bends that are located on the switches. for example if there is a filter on a switch it is most likely you will get a variation of the filter on the patch bay.. a vocoder like sound can shift in harmonics with a little experimentation on the patch bay.

and the sk-1 will function as normal provided that all bends are not activated.. it is highly recommended that you understand how the instrument works and experiment with bends in all modes to make the best and widest use of your instrument. there are plenty of good resources on the web with manuals to download.
