hi,

i do have 2 devices setup under "midi settings".
As input device 1 i have the device A, no device as input device 2.
As output device 1 i have the device B, as output device 2 i have the device A.

i red in this forum that device 1 sends on the channels 0-16 and device 2 sends on the channels 17-32.

when i first tried it worked pefectly. after a restart it was totally different. like device 1 and 2 sended on the channels 17-32 (of course then it makes no sense to specify the midi channel 2 on the "noteout" object).

i found out that a different order in input devices and output devices gives different midi channel depandancies.

it feels a little bit random. Is there a way to make sure or to specify which device uses which midi channel?

thanx,
slx

I'm not sure I fully understand. When you start Pd, are you setting the the MIDI settings every time? Because the settings get lost when you close Pd.

hi maelstorm,

first of all i am really happy that you replied to this post. i got many useful hints and aha's from reading your posts.

also the use of the flag "-mididevout" which i used (found here the info in this post http://puredata.hurleur.com/sujet-3187-more-midi-output-device-options-needed).

since i set the flag, the devices are always listed and the settings do not get lost.
so device A is always input device 1 and output device 2, and device B always output device 1.
anyway, maybe i do not fully understand the use of the flag, the channel the devices are sending seems to be not always the same.
