Hello,
I've been using pd over the last few months on an XP machine, but now poritng a project onto a Mac computer.

Using the test audio and MIDI menu I get audio signal (out of a USB audio device) but no MIDI signal. I tested playing back a MIDI file using quicktime - no problem hearing the Beatles at their best(!)

What could be happening?

the Pd manual directions are a bit esoteric

"To get MIDI working, you have to do the Mac OSX magic to get a USB MIDI interface installed. I've seen this done with Midisport devices and I think you just download the OSX driver and follow directions."

So i did that, and instaled the driver for an M-Audo MIDISPORT device. From the MIDI Set Up panel, the device shows up with its "online" box checked.

From the System Preferences-> Quicktime -> advance panel-> set to "quicktime music synthesizer" is selected.

Running pd 0.39.2 test 5 on Mac 10.4.8

Any help much appreciated! i will keep perusing the net for more info meanwhile.

ps: I don't plan on using any MIDI cintrol, just having Pd play some MIDI files along with some fm synhesis.

I'm a little bit confused. If you are not using MIDI hardware with pd, for control or otherwise, you do not need the MIDI Hardware interface (midisport.) I belive the easiest way to do what you want to do is to trigger events within PD from another midi (sequencer) program. This can be accomplished through "virtual" MIDI channels provided by software such as midipipe etc... Unless someone else here knows a way of playing back .mid files (stored performance data, not sound right?) within pd, you could just load the files with one of many sequencer type programs and trigger pd with that.

Helpful?

I've used what seems like a roundabout way by running simplesynth(which uses Qt music synth), but stillI don't understand how/why pd doesn't use OSX's onboard synth. But that part is functional and now my next aim is to record both the MIDI triggered sound and the oscillators as an aif or mp3 (its not a performance piece but a accumulation piece!).

So thanx Nestor for your reply, coz now I;ll look into midipipe and see what it does, but i beieve I'll need to look for an audio rewire app to route simplesynth's output back into pd. i think that'll be done with something like JACK.
If you know any info throw it my way, its much welcome.

JackOSX and Soundflower have both worked for me on OSX.
