I´m trying to make the pitch change effect included in Yamaha spx900 but I don´t know the way make it.It has delay, level, gain, pitch and fine controls.
Ideas? Could you help me?

Do you have any more details on the type of PS?
If you do a search for 'pitch' and 'shifter' there is a couple of threads on the subject and a few osm's that you can tinker with, nothing that great quality though..
Cheers!

Hi! Type of Pitch shifter? I don´t know what do you referr to...

Ok, I´ve found some things but I can´t open it because I need another version of SM and I can achieve it.
The pitch change is in octaves (+/- 2 octaves)

there are lots of different types of pitch shifter.
I had an SPX 90 about 2 million years ago and the pitch shift was of the ugly time domain windowing variety with granular robotic upshifts. It also had that awful delay>pitch>feedback> loop rising sound that people seemed to use just because it was there, rather than because it sounded nice! I have no idea if the spx900 has anything better.
I say have a look around for a slightly more modern method of the way thay did it.

Synchronised Overlap-Add (SOLA) algorithm, gives an output synchronising the time windows to the BPM , there is an automated version too. Some of the variations may fall under a patent , not sure.

I kept my Korg DSS1 because it sounded so bad it's cool! 12bits w/800k of memory baby!
