I have a casio ctk-481 keyboard, but it doesn't have a pitch shifter like the one in this video:
http://uk.youtube.com/watch?v=ldC0wCQQB-s&feature=channel_page

i.e. 3:20

The keyboard in the video (yamaha dx100) only costs about £50 so i'm assuming that the shifter thing couldn't be that expensive. Even if it will only work through MIDI, my keyboard has a midi in and out.

so my question is, can I buy or build an external shifter similar to the thing on the keyboard in the video?

I built a little 'keyboard' sort of thing on a breadboard a while back. it was pretty much just a signal generator, and the pitch was changed by increacing/ decreacing the value of two resistors

I built a pitch shifter thing by using 2 pots ot increace/decreace the resistance, changing the pitch. I have no clue if a keyboard works on a similar principal, where each key corresponds to a resistance that completes a circuit, creating a note at a certain pitch, but if it is, then ...yeah... using a couple of pots to change the resistance would work, I would assume

of course, a keyboard could work in a completely different way than I'm assuming here (it probably does), so I have no idea if this'll work at all...

sorry to not answer your question but why would you put a keyboard in the GUITAR Building & Customizing forum???? You must be outside your mind.
Oh Hey look at my signature

cause this is a very good subforum for musical gear modification in general?

thesecondraid - I've been considering doing something similar to my casio (CK - 400 i think...) from what i've learned, if the tuner is a pot, you can put a pot in it's place and by restistor-wizardry get it to give you up or down pitch bends ( from various circuit-bender websites).

I don't know, I'm having trouble finding out about this kind of stuff. and I am a total "noob"

there's a possiblity it might be reasonably easy with midi. from what I've learned, there's a board you can buy for making controllers yourself - you just sloder the switches etc. onto it and it's got a socket attached.

if there's something like that inside your keyboard with spare lugs, then you're away.(i think..)

EDIt, it's a CT 420

its touche



actually it's touché

Thanks for all the responses guys!!!
I'll look into the pots and the resistors

Anymore posts will be greatly appreciated

The G in GBC isnt for guitar. Its for GEAR.
