Hi folks, first post here. I am new to pd, coming from the Max/MSP camp.

Setup: Pd-0.38-3 on Mac OS X 10.4.1

Question 1: I want to channel output to multiple MIDI devices (I have two ports specified in my IAC Driver in Audio MIDI Setup). In Pd > Preferences > MIDI settings... I can see these as two devices and select "use multiple devices" to enable them both, although selecting "Apply" seems to last only for the current session (upon next launch Pd forgets these settings). THE QUESTION: Can I use a parameter in midiout to target just one of these output devices? I seem to only be able to access the first device.

Question 2: The help patch for MIDI objects displays a couple of warnings in the output when I open it, should I worry about this?
error: midiin: works under Linux only
error: sysexin: works under Linux only

Thanks a heap.

I realise a long time has passed since you posted this, but in case this helps: the right-most inlet of both noteout and ctlout objects is a number setting the MIDI channel the message is transmitted on. There are 16 MIDI channels. If you go over 16, then you start outputting on the next MIDI device. For example, 17 outputs on channel 1 of your second device. 18 on channel 2, etc.

I am also finding it a drag that PD doesn't remember your MIDI settings. Does anyone have any fix for this?
