Casio MT 600 demo track

Published on Mar 1, 2014 ikworgek·62 videos

"All sounds from the casio.
some reverb and delay.

The MT-600 was a non-programmable home keyboard variant of the HT-700. While not technically a synthesizer (the tones could not be altered and new sounds could not be created), it used the SD synthesis engine and had the same preset patches as the HZ-600 (arranged in a different order). The case of the MT-600 was smaller than the HZ-600, with only 49 mini-keys, but as a home keyboard it did include stereo speakers and auto-accompaniment. The MT-600 included a pitch-bender, which was unusual for home keyboards at the time. Unlike the HZ-600, the pitch bend range was not selectable. Auto-accompaniment used a fixed bass patch, and the "lower tone" sounds of the HZ-600 for chords. Drums were low-resolution 8-bit PCM samples and resembled an expanded Casio SK-5 drumkit. The MT-600 was 3-part mutitimbral for use as a MIDI sound source."

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."

A final outing for CASIO SK Twins (march 2013)

Published on Mar 14, 2013 squidfanny·136 videos

squidfanny on eBay (RSS)

"Very Circuit Bent CASIO SK's, both machine's are in dire need of some servicing. . .

After many years of continuous use as a demonstration piece, my beloved CASIO SK-5 is ready for retirement. The sound is now very distorted and the digital section is becoming very glitchy and un-reliable.
This is a clear sign that the old capacitors need to be replaced.
I'll probably need to remove / re-work some mods too, so this is the final outing for this particular incarnation of the SK-5.

The SK-1 was a recent project, I added my 'Trance-Gate' Step-Sequencer circuit to the machine, but was never really happy with the result. So again, this machine's gonna be re-worked and re-incarnated as something better :)"
