I've just installed rosegarden through apt. I've also installed jack and a low latency kernel through a PPA https://launchpad.net/~abogani/+archive/ppa. I've started jack-server and through the control panel I can see its wiring things through rosegarden.

I've also tried installing qsynth and dssi both through apt. However I can't see any plug ins in the synth plug-in list. Therefore I'm unable to test if this works.

I've tried launching qsynth before rosegarden and I've tried a few things however I just can't see any plugins.

Does anyone know how to get this to work?

I'm using ubuntu 11.04 or 11.10 I think.
