|Blue Pop Tragedy|
This keyboard started its life as a powder-blue-edition Casio PT-1 Electronic Musical Instrument. A classic tiny keyboard that has all the great 80's sounds and rhythms, including the main rhythm part of Trio's seminal (and unfortunately overused for too-hip television ads) "Da Da Da" from the album "Trio and Error." You'll find it under the "rock1" rhythm setting.
I facilitated a bending workshop over at a friend's and the theme was keyboards. So, I dug into this one. I was quite pleased as to the ease of the bend (actually modification) and the results.
After poking around the board for awhile, I didn't seem to find anything interesting. On the bottom of the unit there is a de-tuning trim pot. I ended up just desoldering that and adding a new larger pot and an optical resistor to give me two levels of pitch control.
challenge was figuring out how to place the new added modifications.
dAs suggested just leaving the keyboard part off, which I liked, and
then I noticed the holes in the circuit board for the keyboard support
pins. Ah-ha! With a little bit of hole-widening (very carefully—notice
how close the traces are to the holes) I was able to put the shaft of
pot thru. Nice knob!
I may put a strap on this and use it like a tiny keytar.
I put the eye thing there just to cover up my shitty glue-covered wiring. I always use a glue gun to seal the solder points when I am sure that the wires are in the right place. The wire I use is single core wire-wrap wire so it easily breaks. This allows me to move the board about without worrying about breaking my wires off.
I decided not to paint this one at all as I liked the blue color enough, and it would have been a pain in the ass to recreate all the written directions like rhythms, tempo, volume, tones, etc.
So, even with this very basic pitch bending modification, the sound is really excellent, especially when it is slowed waaayyyy doowwwwnnn. Even tho it's not one of my prettiest, this is one of my favorites.
