Kommentar zu Rosegarden 10.02 Binary Package for Ubuntu 64-Bit (x86_64) von ekkehard

Ugh … the notation editor of Rosegarden 10.02 is still a usability nightmare … it’s practically impossible to insert notes or pauses that move the other notes away, although labelled “insert” operations, they do actually replace things (like, if I want to insert an eighth pause, a neighboring quarter note is broken up in two eighth notes, and one eighth is replaced with the pause).

I still remember the Aegis Sonix program on the Amiga from 1987 that had a perfect notation editor … it’s ridiculous how bad modern software is …

OK, “timidity -B10,8 -Oj -iA” gives OK timing for my machine when Rosegarden is running.

Ahhh … looks like I’m finally getting somewhere!

Now I discovered that timidity is using ridiculously large buffers by default, which was the audible delay that I perceived. When running timidity with “timidity -B10,7 -Oj -iA” then there’s absolutely no perceivable delay.

When Rosegarden runs, there’s some choppiness in the output, however … I yet have to figure that one out.

OK, so after much more fiddling with that … stuff … , I found out that timidity and jackd were in competition about the ALSA outputs. I uninstalled the “timidity-daemon” package, which simply removes the init.d script, and ran “timidity -Oj -iA” from the command line when jackd was running on ALSA. Important configuration options for jackd in Jack Control are setting the frame size down to 256 from 1024 and setting the realtime priority up from default to 10. To run jackd in realtime mode, it is necessary to configure the PAM security manager in Ubuntu. This can be done by editing “/etc/security/limits” as described in the jackd FAQ (at http://jackaudio.org ).

Still, my impression is that using Jack is degrading performance to a degree since there’s now some perceivable latency that wasn’t there before when only ALSA MIDI was being used without Jack.

Anyhoo … at least now both wave audio and MIDI can be used at the same time.
