circuit bent casio sk-1

via this auction
"circuit bent by spunky toofers

here are the modifications

1. 11 switches- controls freeze/holds, pitch related effects, bizarre filters, odd synthesis, self composing random melodies, rhythmic drum varations and much more. use alone or in combination.

2. 5 switches located on the far right which cuts out all 4 voices the instrument can play at once and the drum sound kill switch

3. one reset button

4. one vintage pilot glass lens with a bright blue led underneath

5. master pitch switch enable indicated in black (with this switch you can activate a extremely stable precision oscillator circuit which replaces the original clock signal for extremely stable pitch control)

6. one overall pitch knob (approximately 3 plus octave pitch range with knob)

7. lfo rate knob (lfo activated by pulling up on this knob. activates a lfo to modulate sounds from subtle to extreme)

8. lfo depth knob

9. lfo indicator light- indicates depth and rate activity. vintage new stock soft glow dialco green LED

10. light theremin switch

11. light theremin photo cell (light sensitive wafer that responds to light, shadow, and movements from hand, body, etc)

12. 2 gold dome body contacts (super expressive control of pitch via body contact

13. 16 point patch bay to make various connections in the patch bay via rca cables for experimenting new bends

14. master power switch on/off indicated in red

15. intuitive and through interface with as much spacing as possible for all controls

16. manual and bend diagram emailed to winning bidder

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.
