I've been using ubuntustudio for some time with Rosegarden and not had to do anything much more than configure Jack. Mind you, the stuff I do is pretty light weight.

I've also just downloaded and installed the latest 11.10 and man am I getting frustrated. Although Rosgarden and all the soft synths seem to work fine so far, however, the default XFCE interface sucks. Have been playing around with Unity and trying to configure it to my liking and that is the primary source of my frustration. Unity is not very configurable but it does have potential. I liked the way compiz and desktop cube worked in terms of task and desktop switching on earlier versions but I've had no success with that on versions 11.04 and 11.10. All this messing around, adding and removing desktop packages has resulted in a useless system so I'm re-installing from ground up with the hope that what I learned the first time around will get me to a better place.

Hello all,

Just upgraded my kubuntu to the latest release, and to my astonishment the ubuntu vanilla kernel seems capable of doing a reasonable job rosegarden+jack+qsynth type audio. This is with jack in RT mode with the default fairly conservative settings. I'm not trying to do almost-zero latency audio work here, just trying to play a non-trivial midi file (carnival of the animals as it happens), and it sounds ... well, fine really.

This is the first time I've experienced anything other than practically useless rg/qsynth performance on a vanilla kernel (ubuntu version). First time I've not had to immediately try to compile my own low latency/high resolution/pre-emptive kernel after an upgrade just to use Rosegarden to play a midi file. I'm actually quite happy about this :-) 

I don't follow kernel development that closely - have things been done in kernel v3 to improve latency/resolution/preemption of the vanilla version does anyone know? I guess to do proper pro audio work you still need to roll your own rt or low latency kernel, but it would be nice if the bog standard kernel just played nicely with rosegarden out of the box, for the casual user.

Of course there are plenty of reasons never to put yourself through the potential hell of a distribution upgrade with (k)ubuntu, but for once, for me at least, kernel-midi-rubbishness doesn't seem to be one of them.

Unless I'm alone in my experience with previous vanilla kernels and rosegarden, and you've all been happily using vanilla kernels and rosegarden together for years, in which case ignore me and carry on as you were :-)

Cheers,

Ian.
