i'm very sorry about the newb question, but i've been trying to load a sample into the table for some time now.
after reading the control examples and the audio examples im still lost.
even if i take an already made pd patch. and just put a sound file into the same sound folder as the already refferenced sample and change the message box to it's name i still get nothin. i've tried this with the samplers in the audio folder.
anyone have any idea on how to help me?

Loading a sample into a table

hi again i seem to have a problem with the -resize feature. i can only load the first kick of a drumloop.
here's the patch.. think you can look at it for me?

loops load fine for me.
i guess your whole loops are loading too, but you're only playing the first bit.
there's a number box which says: "chunk size (100ths of a second)"
even if you set that to 100, you're still only playing the first 1 second of your loop. you want to set it to about 400 to hear a typical 4 second drumloop.
anyway, stick with it. everyone feels really bewildered at first...but you get these aha! moments when things just fall into place in your mind. -
hehe ok cool will do gonna go to bed and try some more tomorrow
-
any idea how i could just have pd auto detect the sample length?
-
the output of [soundfiler] gives the sample length in bits. for a 44100hz sample, divide by 44.1 to give the length in milliseconds
[soundfiler]
|
(sample length comes out here) -
do i put one of these after the soundfiler?
/ 44.1 -
read $1 -resize drum
should be:
read -resize $1 drum
other than that you seem to be doing fine...
what you can now do, is take that bit of code you just made, and use it to load new files into arrays in the help docs. (just swap 'drum' for the array names in the docs)
remember though, if you modify the help files, make sure you save *as a copy* , cos you don't wanna go monging up your documentation. -
interesting.
thanks i'll look into it.
