Hello,
I've been trying to work with a very large MIDI file (over 420 bars and
50 tracks) and I found some problems with both Muse and Rosegarden (both
in their latest released versions).
First, Muse seems to go faster in tempo than what is set in the midi
file. To test this, I imported the same file in both programs and set
both to sync with jack and started playback. After some time Muse was
ahead of Rosegarden. Why is this happening? Both are set to the same
tempo (I have Rosegarden set to sync to the system timer). Beside this,
I found, in Muse, that some notes in one instrument were imported with
longer duration.
Second, Rosegarden crashes when I scroll horizontally through this large
file. It doesn't matter if I do it fast or slow, I just have to keep
scrolling for some seconds and then it will crash and make the X server
to restart. If I manage to get beyond bar 320, I find that the display
gets corrupted and the segment boxes disappear but the midi notes are
still being drawn (it looks like the notes keep going outside the
boundaries of the segment container). I found the same problem in
previous versions of Rosegarden and it's present using two different
distro versions (I tested in Ubuntu Breezy and Dapper).
So, these problems made both programs unusable for this particular
project... I wonder if anyone suffered of the same or have any idea how
to solve this problems. Any help will be very appreciated!
Thanks!
Hector.

Ok, I found the source of my problems with Rosegarden: the crash seems
to be related to using the Nvidia proprietary drivers (with the open
source driver it doesn't happen... maybe it is related to the kernel
with Real Time preemption patches that I'm using). The corrupted display
is gone in version 1.2.3 (sorry for not double checking this).
The timing problem with Muse is still there...

How did you come to conclusion that MusE is too fast and Rg not too slow?
I'm not saying that MusE is not in error but it's a valid question to help us
understand.

Regarding my problem with Rosegarden crashing X when scrolling, I found
that whenever I use the Nvidia proprietary driver it happens, and using
either a RT preempt kernel or in a non RT one (in the second one took a
little bit longer to make it crash).

If you try 'file themidifile.mid' on the original midi file you imported, what
information does it print?
Possibly it's a format that muse does not handle correctly.

You mention that you can hear that it's faster, in my mind that means that it
must be quite a bit faster, how much faster do you recon it is? %, bpm?
I've tried to import some mid files and compared with how timidity play them
and cannot detect any audible difference. There is some difference in how
long timidity and muse reports the pieces to be but I can't be sure they
count the same so it's hard to tell.

Robert
