Hi, I'm trying to build a patch that routes notes, CCs and pitch bend from a keyboard to different synths. Everything is ok for notes and CCs, but I have a problem with the pitch bend. It seems that [bendout] can outputs only a range between 0 and 16384, while the correct range should be -8192 +8192. I tried to force negative values but it seems that bendout can't go below 0.

use [- 8192]
because 0-8192 = -8192 and because 16383-8192 = 8191
that is, in unsigned values, 8192 is the middle of the range.

You right, but I already tried this:
#N canvas 93 232 450 300 10; #X obj 82 77 bendin; #X obj 82 102 - 8192; #X obj 82 130 bendout 1; #X connect 0 0 1 0; #X connect 1 0 2 0;
And bendout had only a range from 0 to 8192, it didn't go below 0.

Strange I tested (with rosegarden and gmidimonitor) on 0.43 and it worked outputting the whole range -8191 to 8192. Lorenzo

This depends on how the software is "displaying" pitchbend. Pd always uses 0
- MIDI does always transmit 7-bit values from 0 - 127 (except for
SysEx). This is a 14-bit message cascaded by two 7-bit messages - each going from 0 - 127.
Generally the msb is being used and the lsb is left at 0 (maybe it's the other way around). This means the center value of Pitchbend is 64 0. You can eliminate the second byte by dividing by 128.
For displaying the value is offset by 8192 by certain softwares to show negative values. Some people might think it looks more understandable to have the same range going negative or positive for bend down / bend up. But the numbers still go from 0 - 16383. Center is 8192 or 64 0.

Thanks for all the feedbacks. On Debian Wheezy I tried the following setup: vkeybd -> Pd -> qmidiroute
On 0.42.5, the numbers starts from 0 even with the [- 8192] object. On 0.43, as Lorenzo said, I can get the correct range (-8192 8192), so it seems to be only a 0.42.5 issue.
I can't really see how 0.42.5 could use or output a different pitchbend range than 0.43. If this was the case all patches using pitchbend would be broken on 0.43 if they were made with an earlier version. I would call that a major disaster.

I've been using pd-extended 42 for nearly two years now, and all what I tried with pitchbend was with that, and it worked.

Try with vanilla 0.43 and see if it works there. Please file a bug

Neither do I! I just don't believe that it works differently on 0.43 (which I don't have installed unfortunately) compared to 0.42.5.
0.42.5 works as expected!

As I previously said, 0.43 vanilla worked for me. Today I tried different versions of pd-extended 0.42.5 (puredata.info repos, l2ork) but none worked. Perhaps I messed up something, so I'll retry with a clean system or I'll just use 0.43 vanilla.
Hello list, on February 24, 2010 I posted to this list concerning [bendout], which (on pdextended 0.41.4) generated other MIDI messages in Linux-Alsa than in MacOSX or Win. A patch was submitted by mrpeach to fix this ([ pure-data-Patches-2958837 ] Fix bendout on alsa). If this has been patched in 0.43 (I did not yet try it) then indeed [bendout] would behave differently now than before.
