<div>thanks for your hints!</div>
<div> </div>
<div>I created a midi file in ableton, exported it and then read it with the midifile-read-help-patch. </div>
<div>This is what I get after reading:</div>

<div> </div>

<div> </div>
<div>And this is what I get after the |dump 0( message:</div>

<div>
<div>
<div> </div>
<div> </div>
<div>The differences that I noticed:</div>
<div> </div>
<div>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".</div>
<div> </div>
<div> </div>
<div> </div>
<div>midifile: Header chunk division: "0x60: 96 ticks per quarter note"</div>
<div>midifile: Header chunk division: "0xE714: 25 frames per second, 20 ticks per frame"</div>
<div> </div>
<div> </div>
<div>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"</div>
<div> </div>
<div>This info is not present after loading the file that i recorded with [midifile].</div>
<div>____</div>
<div> </div>
<div> </div>
<div>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.</div>
<div> </div>
<div>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.</div>

> 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?<br/>
<br/>
You have a bunch of notes right at the beginning (tick 0) that go on<br/>
and off instantly. Not sure how you did that, it may confuse ableton.<br/>
Maybe you could take a simple file made in ableton, that works in<br/>
ableton, and load it into [midifile] to see what it looks like.<br/>
Ableton may be looking for a time signature or something like that in<br/>
the first chunk.<br/>
<br/>
<br/>
> When I recorded the file, I sent the 2,005 message into the right inlet of [metro], but that is correct, isn't it?<br/>
<br/>
If that's 2 point 005 not two thousand, yes. But that only tells the<br/>
[metro] how fast to tick, it doesn't write anything to the file to say<br/>
how fast to play it. Also loading a file with a bpm and time signature<br/>
doesn't automatically set the metro to match those values. The help<br/>
patch is set up so that the first bang sent to [midifile] after<br/>
loading a file willl take the timing info from the first chunk and set<br/>
the [metro] for you. (The latest version of the help patch will do<br/>
that, older ones may be different) Click the bang "step_one_tick".<br/>
