Casio SA bending tutorial
uçÚº[
I’ve been speaking with a very skilled bender in the UK named Paul Parry aka Oceanus. Paul takes an engineers approach to bending and has come up with some very impressive results. He and I have worked together to bring you the following tutorial on bending the CASIO SA keyboards. These modifications are all Paul’s designs. I have been working with Paul to illustrate his designs and make them available to the public through casperelectronics. Paul has posted several videos of his creations on Youtube which you can see here.

I had contacted Paul about his mods on this. He was helpful. I shy and still learning the electronics language was still confused when I got the information but did not follow up. Thank-you Paul and thank-you Pete for the new user friendly illustration at the top. I think it might help to bridge concepts in my mind that can be applied to this + other things. Bravo!

The 3 pin crystal is a crystal resonator. You probably could just swap it out for another resonator with the correct capacitance. Looking forward to trying some of these bends.

Correct, it is actually a Ceramic resonator, which is a cheaper version of a metal cased crystal. They build the capacitors inside to save on cost for mass produced items. I have got the SA-5 to run down as low as 5.8Mhz, but not found many resonators that go much higher than about 10Mhz. A common flavour is the 3.56Mhz type used in loads of toys from Furby’s to Speak and Musics…

Without opening mine I’m thinking that these same bends + more are possible with the Casio Rapman? It has a very similar circuit as the SA series from what I remember. A pitch mod for the SA has always been a much needed bend in my opinion.

Yeah! I recently bought an M-100 from Casio (SA-5 Clone) and bent it almost exactly after Paul’s tutorial. I only used different IC-Legs for the “5th Switch” and yeah… it’s fun to fool around with it!
