Hi, I am a beginner with Rosegarden and indeed with sound editing. I am
struggling with what appears to be everybodies first problem: getting
sound out of my computer.
The FAQ:
https://www.rosegardenmusic.com/wiki/Frequently_Asked_Questions#playback_and_recording
has 2 lines of explanation and then declares the rest obsolete. Those 2
lines mention ALSA (apparently the Linux kernel sound system) and JACK,
but it is not clear whether I need to use (and configure in RoseGarden)
both ALSA and JACK, or one of them excluding the other, or that they
co-exist. I would appreciate some elaboration.
What I have now:
Kubuntu 20.04
Rosegarden "Yesterday" 19.12 (packaged with Kubuntu).
When I first started Rosegarden it warned me I need a software
synthesizer, specifically QSynth: but QSynth is not in Ubuntu.
Instead I installed anything I could find for JACK:
JACK Keyboard
QjackCtl
RoseGarden appears to start jackd:
/usr/bin/jackd -T -ndefault -T -d alsa
I also installed anything mentioning fluidsynth:
Fluidsynth DSSI
SoundKonverter
The former mostly installs libraries, and an application
fluidsynth-dssi.desktop, which refuses to start because it says it needs
the program 'jack-dssi-host' which it can't find, and neither can I.
Finally I installed anything mentioning timidity:
timidity itself
(and soundKonverter again)
Now I managed to write a 1-bar composition in Rosegarden and save it.
When I play it in RoseGarden, it does not complain and it appears to
oblige, the indicater at the lower left shows activity: but no sound.
The apparatus and instrument are default: Audio #1.
I could choose Synth-plugin but it cannot find any plugins.
I also exported the test composition to MIDI (.mid), and when I close
Rosegarden (won't work if it remains open) and run:
$ timidity /home/tom/rosegarden/test.mid
Playing /home/tom/rosegarden/test.mid
MIDI file: /home/tom/rosegarden/test.mid
Format: 1 Tracks: 2 Divisions: 480
Copyright: Copyright (c) xxxx Copyright Holder
Cue point: Created by Rosegarden
Cue point: http://www.rosegardenmusic.com/
Track name: test
Playing time: ~6 seconds
Notes cut: 0
Notes lost totally: 0
I do get sound.
So my question is:
what is missing in the components and configuration?
