[linux-audio-user] Muse timing and Rosegarden crashing X

[Hector Centeno-Garcia]

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.
