I want to play several samples with different pitch variations.
I've used the contents of the G09.pitchshift.pd example in order to reproduce a sample altering his pitch. That I've acomplished ok.
But now I wan't to be able to play different samples at the same time with different pitch variations. So I suppose I will need to have different instances of the G09.pitchshift.pd patch, but I don't know how to arrange them. Ideal will be a dynamic list, or a hash containing this patches, one for each sample I want to play, but is there anything like that in pd?

Thanks,

The best thing you can do in this case is use an abstraction. This means creating a blank patch, copy the pitchshifter code inside and create inlets and outlets for audio and parameters, also rename the delay lines (which are used i believe by the pitchshifer) to a $0- prefixed name:

if the is this

[delwrite~ myDelayLine]

turn it into this

[delwrite~ $0-myDelayLine]

Also rename the delaylines in the [delread~] or [vd~] objects.

Save this new patch, preferrably in the pd extra folder and call it something like pitchshifter.pd. You can now create a new patch and inside have as many [pitchshifter] objects as you need.

Hope that's a bit clear.

Thanks very much Domien!!!
It have been of a great help. Now I got that module playing several samples with their pitch variations!
I liked your music too

Is there no possibility to make it dynamically?
I mean, to create a new pitchShifter instance in runtime?
If that's possible I will need to figure out how to adapt all my logic to something dynamic too, like a [select] object I have to route input into pitchShifter modules...

Dynamic object creation is certainly possible in pd, although i've got no experience with this myself. Here's a link to get you started:
