I'm guessing your patch receives the 256 values in a list?

You can extract the Nth element from a list with a message box like [ $N (

But for a list length 256 this could get tedious to patch. What I suggest is making a Java program to make the patch.

Make a patch to extract the right parts from the list for a short list, say length 4, perhaps with a [ t l l l l] connected up to [ $N M (, where M=N-1, each connected to [ unpack f f ( ==> [ tabwrite ] . If you create the message boxes last, it will be easier to write the program.

Then write a Java program to generate the patch you want. It's best if the patch generated is a complete abstraction, so you don't have to edit the output patch each time you edit the Java program (say if you want different length lists).

Here is an example of a Java program that I wrote to generate a patch with 256 number boxes in a 4x64 grid. It doesn't follow my guidelines for being a complete abstraction - I edited the patch afterwards to add more stuff, which will cause me problems next time I want a different sized grid....

public class NumberGrid4x64 {

for(int y = 0; y < 64; y++) {
for(int x = 0; x < 4; x++) {
System.out.println("#X floatatom "+(7+26*x)+" "+(42+16*y+4*((int)(y/4))+4*((int)(y/16)))+" 3 0 0 0 - #0-"+y+"-"+x+"-r #0-"+y+"-"+x+"-s;"); count++;
}

int count0 = count;
for(int y = 0; y < 64; y++) {
for(int x = 0; x < 4; x++) {
System.out.println("#X obj "+(120+200*x)+" "+(42+16*y+4*((int)(y/4))+4*((int)(y/16)))+" r &#92;&#92;&#036;0-"+y+"-"+x+"-s;"); count++;

int count1 = count;
System.out.println("#X obj "+(500)+" "+(18)+" t a;");

Hi all

slowly pd drives me nuts. I do have installation issues which I cant get my head around. While I was able to install pd in loads of different ways (and it runs all the time just fine) I have problems installing externals (one exception: gridflow). At the moment I have pd installed with the help of apt-get, together with gem and pd-externals. when I start pd, those libraries arent loaded though. And I cant find the locations of them. So how do I have to edit .pdrc to bind them?

and if I want to install pdp and pidip (in case they are not inside this pd-externals package) where should I install them?

Or should I consider a different installation method altogether to be able to be uptodate with new versions?

I appreciate every help I can get.

kind regards

martin
