"This is a Casiotone 701, that was outfitted with a simple mod and sealed off to the outside.
What happened was...
I was playing a gig with my band, and my bandmate spilled wine on the keyboard during our set. It immediately failed. On our set break, I decided to open it up to try to wipe up some of the wine on the inside and see if it might come back to life, and that is when I discovered this after market modification and accompanying note/diagram. It was wrapped inside a spongy wrapping and stuffed underneath the key bed with the note rubber banded to it. The mounting hole was boarded up with an inconspicuous black panel; Thus, I never really noticed anything suspicious. I had a chance to get the keyboard up on the bench and trouble shoot the wine spill. Basically, it dried itself out into a functioning order. (I never trust a repair if you didn't do anything to fix it.) But anyway, this mod is very simplistic - incorporating individual 1/4 outputs for drums, rhythm and keyboard, respectively. The most promising feature is a keyboard fuzz output. They also took the time to wire a computer pin out to the keybed, some familiar but ancient looking 20 or so pin connector. I'm not sure if I will be able to utilize their function.
Are there avid mystery-mod cult practitioners that you know of who would hide such a thing?"
If anyone out there knows, feel free to comment.
