back again with a fresh new bug.

This one is very very hard to explain. Also pictures would not help.
So heres a step by step reproduction
First you will need a simple 1-Bar-Midifile with any content. Best are short notes, 16ths or something like this.
Or you can download this one http://rapidshare.com/files/40572215/example.mid.html
It is a 1-bar drumloop. The notes are very short for best bug demonstration. Save it wherever you prefer. Now pay attention please and follow the steps exactly !

1) Open up E-XT with the default sequencer loaded.

2) Insert 3 new Miditracks so that you have 4 at all. Delete all other Tracks and the empty
midipart.

3) Then Browse to the location of your (or mine) midifile.

4) Then Drag and Drop it to the 1st Midi-Track and (this is the important part), try to drop it
as exact as possible on the ZERO-Timeline point. You could also say on the first Beat.
The Part gets imported and appears in the sequencer window.

5) Repeat Step 4 with the same file but the 2nd Midi Track. BUT (mostly important) shift the
"dropping-Point" ONE Beat to the right, so that you drop the Midipart on Bar 1 Beat 2.
You will probably notice the first differences visually. But please go on.

6) Repeat Step 5 for the remaining 2 Midi Tracks, but always shift the Dropping Point one Beat
farther so that you put the last part on the 4th Beat of Bar 1.

7) you should now have 4 Midi Tracks with 4 parts, which should be of the same content, because you always used the same Source-File.

BUT :

They are of the same content in some way, but in some way the aren't at all

What happenend, is the hardest thing to explain. Maybe you should load a Drum-VSTi or something to the tracks to hear what happened :
The original starting point of the source midi (Bar 1 Beat 1) gets shifted out to the left side of the part with an amount that is exactly the amount where you shifted the dropping zone before. (regarding the grid also) . Additionally every note gets longer about the same amount.

You can check this, by opening the editor for each part.

I hope this explanation is understandable, because the bug itself is hard to explain plus i am no native speaker

questions ?

But isn't what you described just using one ghost edit in different tracks? From that point, it's totally understandable.

huh ?
have you followed the procedure ?

what does that have to do with ghost editing ?

They are not ghosts, and that is not how ghosts should behave anyway

.

It's a bug alright, but you don't need to do all that.
Just dropping the file somewhere besides the beginning will always give you a messed up part. The part thinks that it begins at beat 1 even if you drop it somewhere else. Drop a file on beat 2 and you will get the note ons that start at beat 2 from the midi file at the beginning of the clip. The lengths will have negative values. Drop a 1 bar clip on bar 2 and you won't see anything (looking at event list will show you all the notes with negative lengths).

Sequencer:

Correct:

Wrong:

Adding to issue list:
J29- Parts made by dragging a midi file to a track have note ons tied to absolute song position (note offs are relative).

Yes, and the problem is that this doesn't happen with any other file than this in your example. I think it's because note info is to short. On any of my midi files, everything works as expected.

Just my first assumption, sorry for that

Uh, how many files

I'll check and report results later...

soma · Post by **soma** » Mon Jul 02, 2007 5:53 pm

Try any of them. (good resource to have anyway)

Thanks for midi files, it's great source!

But, I'm still unable to reproduce

Here is the picture

Maybe i'm doing something wrong...

Hmmmmm. Interesting that there are different results.

Well i found no parameters or options that resolved that issue.
Dunno

Skeemo-
How did you make the .mid file (give as much details as possible)?

skeemo · Post by **skeemo** » Mon Jul 02, 2007 7:36 pm

i found it a time ago somewhere in the www included in a bunch of drumloops.
i did not made it my own.

That file hung XT1 when I dragged it in. I wonder if it is faulty or has special information.

kejkz · Post by **kejkz** » Tue Jul 03, 2007 7:41 am

I've just tried importing that file in Tracktion 2, and everything works, there is no additional information in file, AFAIK.
