After loading a midi file (type 1) in max, I want to know the program change number used for each track. I tried detonate, but he gives no info for the program change...

For example, in a midi file with 3 instruments, how can I know that one instrument use program change 0 for a piano sound, another one use program change 32 for a bass, etc. ?

If your question is about knowing what program change messages are contained in the file, you can use [pgmin] to track the messages. On the other hand, if your question is about which instrument produces a piano sound for a given patch number, that's often not standardized--unless they are using General MIDI--but a function of the synth itself.

Indeed, my question is about knowing what program change messages are contained in a midi file.

I've looked to the pgmin but I don't understand at all how it works. In patch help and reference page it's always used with the input connected to nothing (!?), so how did it receives MIDI information ? And from where ?

In my case, I have a midi files which is played by a detonate object. So I have to connect one of the output of detonate object to the input of pgmin ?

Thanks again for your help, I'm totally lost with this...

[detonate] should be able to output controller 0, but you could also use

[filein], read at word, and search for the hex string for controller 0.

What if you used [seq] instead of [detonate]? If all you need to do is play MIDI sequences, would that work? You could then connect the [pgmin] object to the left outlet of [seq]. Check out the helpfile for [seq] for instructions on loading and playing MIDI files.

In fact, I use detonate because I have to deal with midi file type 1.

To explain a little more, I have to load a midi file (type 1) and played each track with different vst sounds. For example, if my midi file have 3 tracks : Acoustic Grand Piano / Acoustic Guitar (nylon) / Slap Bass 1, I have to send the piano track to a vst~ object and use program change 0 to play it, then the program change 24 for the guitar on another vst and the program change 36 for the bass on a third vst.

So that's why I'm trying to automatically get the program change of each track to assign the track to the right vst preset.

Unfortunately there is no Max object for playing (or analyzing) universal midi files.

But you could try the external 'ajm.midi2coll' from Adam Murray.

I tried with seq and pgmin doesn't work. But I think I'm doing mistakes.

It's the first time I use MIDI in max so I discover a new (complex) world :-)

I'm looking at [mtr] but I don't understand yet how it works.

Thank you, I'll take a look at this object.

Oh I didn't saw your answer broc.

Have you checked the MIDI tutorials in Max?

Yep I've checked the MIDI tutorials, but I have to spend more time to understand all objects.
