hi derek,

thank you for your answer.
i spent some time looking at gem, that is good alternative, but for a
different kind of performance from what i am doing atm. 
i am using my own patch mixer, a modified version derived from one by
tatiana de la o, that was derived from the vj pacth by lluis gomez.

so, by the time, deformation took place, and identity came out.

i know pdp is not very fast, but the language i am developing with it is
quite simple and it does not require high speed: lets say, i often
managed to play audio and video from the same machine, a little 12
inches. 

though i will have a look at gem soon, to make something out of it.

for public utilities:

i tried the pd-extended you told me, following your instructions:
it loads the pdp-pidip library, but crashes (with me) if you try to open a video.
actually all the extended versions i tried tend to crash.
pd-pdp-pidip, at least in the old installation i made with you, sara, tom and
aymeric in montevideo was slow, but it never crashed, not one
time in two years of intense use.
unless of course if i was loading a video with the wrong codec or something
improper like that.

so last night i decided to disinstall everything, and start from zero again.

the problem was xfree in conflict with X11.

the installer from Hans-Christoph Steiner works on mac osx 4, and pdp as
well.

i have it running now, with my patch.

it took me quite a while, but i can assure it is possible to install it
and Sara Kolster instructions are not yet  out of date:
i found them very handy (thanks :*)


so, i am quite happy, time to go for a walk in my home town, its a sunny
hot day :D
see you soon, let me know when are you around amsterdam, 
maybe we can do something nice in ascii.


ciao ciao 

xname.
