Hey Martin, Thanks for your message. I looked for mrpeach in deken, but the only result I get is mrpeach for extended ( i am on mac os). Does that mean that I cannot use it?

Best, Jakob

hey, yes i think so because it seems that [seq] does not offer to specify some kind of ticks when writing to a file. hmm.

Have you tried [midifile] from mrpeach? It can write most of the tags.

Then I opened the help file directly from the ../Pd/externals/mrpeach-folder by double-clicking it and I followed the steps for writing to a file. I

• choose a file
• put the 2 ms into the right inlet of [metro] and then start [metro]
• hit some notes on a usb midi controller connected to pd (the [notein] shows notes coming in)
• hit |flush(
• stop the metro

Then I copy the newly created midi file into ableton, but I cannot see any midi notes being displayed for that file.

Maybe try to load it using the midifile playback subpatch, You can set the verbosity to see what was recorded, if anything. possibly ableton expects some meta information at the start of the file.

Hey Martin, thanks for the hint. When I read a recorded file that should actually have some recorded notes in it and then load it again with the midifile-read-help-patch, then I get this (verbosity = 3)

Does not look like something has been recorded, right?

The last line shows the track chink is 35 bytes long. Did you play it to the end? The third outlet of [midifile] emits a bang when it gets to the end. If you waited a while after starting to record there may be a long pause before something happens. The [dump 0( message should output the entire track to the Pd window.

So it must have recorded something. But when I imoprt the recorded midi file i ableton, then I only see 4 different , very short notes (c1, c#1, d1 and g1) at the very beginning of the piano roll. But of course I would expect the notes being all over the time line. Hm, might there something be wrong with the timing information?

You have a bunch of notes right at the beginning (tick 0) that go on and off instantly. Not sure how you did that, it may confuse ableton. Maybe you could take a simple file made in ableton, that works in ableton, and load it into [midifile] to see what it looks like. Ableton may be looking for a time signature or something like that in the first chunk.

When I recorded the file, I sent the 2,005 message into the right inlet of [metro], but that is correct, isn't it?

If that's 2 point 005 not two thousand, yes. But that only tells the [metro] how fast to tick, it doesn't write anything to the file to say how fast to play it. Also loading a file with a bpm and time signature doesn't automatically set the metro to match those values. The help patch is set up so that the first bang sent to [midifile] after loading a file willl take the timing info from the first chunk and set the [metro] for you. (The latest version of the help patch will do that, older ones may be different) Click the bang "step_one_tick".

Hey Martin, thanks for your hints!

I created a midi file in ableton, exported it and then read it with the midifile-read-help-patch. This is what I get after reading:

The differences that I noticed:

In the ableton-file the "header chunk division" is given as "ticks per quarter note", whereas in the midifile-file it is given in "frames per second and ticks per frame".

midifile: Header chunk division: "0x60: 96 ticks per quarter note" midifile: Header chunk division: "0xE714: 25 frames per second, 20 ticks per frame"

In the ableton-file there is an info given about the time signature: "Time Signature 4/4 36 clocks per tick, 8 32nd notes per quarter note"

This info is not present after loading the file that i recorded with [midifile].

You have to add it yourself, since [midifile] has no idea what time signature or tempo you are using (when writing, the ticks don't have to be in real time). With the latest version of [midifile] there is a [meta( message for this. With earlier versions you can write the meta tags directly, for example to get the time signature, Time Signature 4/4 36 clocks per tick, 8 32nd notes per quarter note you can send [255 88 4 4 36 8{ and the tempo [255 81 500000( sets 500000 microseconds per quarter note.

You can find more info here: http://www.music.mcgill.ca/~ich/classes/mumt306/StandardMIDIfileformat.html

---

Furthermore, looking at the first lines of the dump-info of the ableton-exported-file, we can see that there is also one note being played at tick 0, but I did not actually put a note there. The same applies for the [midifile]-recorded file. I did not play notes directly after hitting the record-[bang]. I don't know how these notes on the first tick (0) have gotten there.

As a side-note the help-patches that I am using are from 2010 (write-help-patch) and 2011 (read-help-patch). These were included in the mrpeach_v0-0-extended package that I downloaded via deken.

Hi, okay so I installed the mrpeach-v0-0-extended package from deken on my 0.48-vanilla on mac osx.

any reason why you're not using the latest 0.50-2?

Hey Alexandre, well, that is a legitimate question ;-) Well, I had not used pd for quite some time and then - one year ago - I started a big university project with the old version that I had installed. I installed many externals and set many startup flags and so on and I just did not want to do this all again as long as my university project was still going on.

flags and preferences don't get overwritten when you upgrade

there's no such thing as "for extended" on deken. there are many uploads that have a version numer "v0.0.extended" which means that this is the same version as was used in the last Pd-extended release.

if the external shows up in the deken search results, there's usually no reason to assume that it won't work, regardless of version. (although, if you only get a "v0.0.extended" version you can assume that either:

• (the library is bug-free)
• the library is unmaintained
• the library author doesn't bother with new fangled things like deken
