Ah right, I might not put one on mine, but I will bear it in mind for any future projects, I'm quite happy with what I've got so far. Thanks anyway, keep up the awesome projects!

Hey I guess you've probably moved on from this project, but I was wondering if you could tell me how you did the pitch bend mentioned in this modification? I've tried a power starve on my own PT100, which does drop the pitch, but not smoothly, so any advice would be really useful on making a more theremin like pitch bend control. Love all your other projects,

Hi,
I was wondering if you could help me. I have this exact same keyboard (Casio PT-100). I recently bought it at a second hand store. It won't power up and I'm dying to unlock it's nifty 80's sound. My power source is 7.5 DC, and I opened it up to check the solder points, but I just don't know what's wrong. Any help would be greatly appreciated.

Thanks,

Hey, remember how I said I was looking for PT-100 bends? Well I just finished bending mine today, I'm really pleased with the way it came out. I took a page out of your book when I made the schematic, splicing the pictures together. I think I found some original bends too! Check it out here:

VCF stands for voltage controlled filter. it pretty much implies that the filter can be modulated by envelope generators or LFO's(low frequency oscillator), or anything with a CV(control voltage)out. there are many different VCF's you could build, but each will most likely need to be adapted to the instrument you are modding. as far as LFO's, i'd recommend downloading the ne555 datasheet(the biggest file you can find). it will have examples of application circuits in it. i use the 555 and the 556 a lot, but you could use op-amps too. just start googling, you'll find lots.

woah. well uh good for noys toise.

nt where did you learn, or get the schematics for filters and oscillators? is there like a sweet electronics book that could help me with that? what's a vcf?

sorry friend, better luck next time. in the meantime you should relax and make use of what you've got. life's too short for namecalling, y'know?

I knew some fucking hipster with 185 dollars to blow was going to snatch this up. looked at his other purchases, all ironic bullshit. fuck them, I was gonna buy this thing and LEARN ALL THE SECRETS, but no my grandparents didn't die and leave me a hunk of money to jack off hookers with.
