[PD] Re: [PD-announce] new [hid] release + simple mapping objects

[cyrille henry]

hello,

Charles Verron has made a collection of external for this purpose.
it on the pd utilities you can find there :
http://www.la-kitchen.fr/download/kitchen_hardware/5_utilities/

it use a lot of zexy objects, and mabe some other lib.
this collection was disigned for signal at constant rate (unlike midi)
there are tools for visualisation, some filter exemple (median filter, 
IIR, FIR).
you can find also debouncer for binary input, etc.

you should have a look there.
maybee I sould put them on the cvs.

cyrille.
