Thanks for the suggestion. I'm not sure I can use this method, though, because I have to be able to write it out as well. According to the help documentation, the '-raw' flag only applies to reading files. Is that correct?
Anyway, I tried it and I'm getting a usage error:
error: usage: read [flags] filename tablename... flags: -skip <n> -nframes <n> -resize -maxsize <n> ... -raw <headerbytes> <channels> <bytespersamp> <endian (b, l, or n)>.
Here's what my patch looks like. I'm not sure what I'm doing wrong.
[read -raw 0 1 8 n Default.syx array1( | [soundfiler]
There's no "header" in the file, it's just raw data for a Midi sysex message, and I want to read each byte as an integer value in the range of 0 to 255.

It's probably very obvious, but I can't figure out how to read and write files containing arbitrary binary data. I know there are objects for reading and writing sound files, and there's [textfile] for reading text files, but I want to read and write binary files, and interpret each byte as a 16-bit integer. Does anyone have an example I can look at? Since they will be small files, I just need to read them sequentially, I don't need to jump around in the file randomly.

Well, you can write it back as a soundfile in the formats that [soundfiler] supports. But if it needs to be saved in the original format, you might want to try some of the other suggestions.

[read -raw 0 1 8 n Default.syx array1( | [soundfiler]
[soundfiler] only supports 2, 3, or 4 bytes per sample...
There's no "header" in the file, it's just raw data for a Midi sysex message, and I want to read each byte as an integer value in the range of 0 to 255.
...which would be 1 byte. Definitely try the other suggestions. :-)

Thanks. I guess I'll have to try another approach.
I changed the sample length to 2 (I didn't read the documentation very carefully, I thought the sample length was in bits, not bytes) and now it works, but I'm left with an array of floating point numbers, and I still have the problem of writing it out again.
I'm still getting a warning message, but I'm not sure what it's trying to tell me:
warning: array array1: clearing save-in-patch flag

Hi when running pix_opencv morphology I get a weird GEM error Do I need a CVS version for this to work with 42.5 extended?

I'd just uploaded a version of pix_opencv binary objects compiled in MACOSX 10.6 tested with Pd-extended version 0.42.5-extended - it's a svn revision
probably the version you where using was compiled against gem version in extended 0-41 ...
....
mmmm ... as you know macos is not our development platform, so it's possible you find some more bugs :) but morphology is working well :)
let me know ....

Works great thanks so much. I love the pmpd addition to the examples Are you planning on adding any livido support to your stuff?
