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.
