Rosegargen + Fluidsynth - no sound while recording

[Fernando Gomes]

Hi

I'm trying to use Fluidsynth DSSI plugin in Rosegarden (on Ubuntu
Studio 8.04) to record some midi tracks, using my midi keyboard. I
'virtually' connect the soundcard midi (TASCAM 122) in patchage to the
midi recording input in Rosegarden and start recording on rosegarden,
I see the track being updated with my midi events (keys I press on the
midi keyboard), but I have no sound output. If I stop and replay then
I can hear all the keys that were recorded, so the fluidsynth plugin
is working. How can I hear it during recording? Or do you suggest
other configuration to do this kind of recording? Using QSynth instead
of the Fluidsynth DSSI plugin?

Thanks!

Fernando
