That's a nice track, I like that backing. Is it processing the
guitar? It seems more like a snippet from a session than a finished
track. I like the little high pitched glitches here and there, as an
interruption.

salut maybe somebody may have a look at http://www.weiss-archiv.de the rephlex-tracks were made not only with pd but it played a great part in makin sound gruss m.weiss

wow i didnt expect that resonance i dont know where to begin first all tracks are done with a 233mhz win32 machine with emagic logic so nothing is synthesized in realtime ive made the sounds with vst-plugins, pdvst and pd standalone, put the files into logic and began to build regions, so you can say a cut and copy compilation mostly worked at the sounds with very simple solutions like rounding- and math-functions, pitchtracking and a patch called "slicer" from forum für umlaute i guess ive burned some sounds on cd and skipped it it happens that from a sound a sound is done and again from this one and so on and at the end theres no "original sound" but only "variables of sound" that workaround was not very intuitiv so im working on a gop-system within pd to make things easier ive lost much time in building an arrangement-modul with all comfortable things like copy and paste, and selction mechanisms but this wasnt satisfied enough now im using logic for the arrangement-part and pd for the synthesis on a new machine of course and maybe there will be a new cd this year and an own music-label????? thanks greets from nürnberg m.weiss

hi,

actually i am not using sfwrite~ for this track, my recording application was timemachine (linux only / jack). but it produces a WAV in 32bit float IEEE that no pd external is able to read the header information (samples, samplerate, channels etc).

i did look at the source (see below) of soundfile_info (iem) but i am not sure where to start...

cool thanks claude. not sure if you'll take this as a compliment, but your music is pretty monged! i'm gonna dj some of this at a party next week.

Thanks :)

The Pd patches are here:

but be aware that they do stuff on loadbang, including writing files...
