kind of a pitch shifter

[percuson]

On the web I found a video how to build a pitch shifter in Max/MSP
pitch shifting in Max

I tried to rebuild this in usine...

I also added a feedback, which results in strange sound effects.
The tempo sync button is not really a tempo sync. It only sets the delay time to the selected time period. But it helps to get something like a sync.

It's not finished yet, but maybe you can test it and give me some feedback.

Merry Christmas!!!

thanks a lot !

Check it out. I tried to make it the most simple way... It should be no problem to get how it works.
It took some time to find out which ramp type is needed (down for tronsposing up and up for transposing down) and how to calculate the pitch. Have a look at control sub-patch to see how I did it.
The pitch delay sub-patch is the heart of the patch. Don't wonder abaout the ramp in the main patch. It is only there, because I had some trouble synchronizing both delays without any noise. It only gives the start signal for the ramps inside the sub-patch.

If you have questions, don't hesitate to ask.
