Hi,
I'm running Rosegarden 10.02 on Ubuntu Lucid and am having problems with
audio output. I am not using external midi hardware so am reliant on
software synths.
The steps I've taken are:
Run qjackctl, run Qsynth (which has been loaded with Unison soundfonts).
In Rosegarden I've selected General Midi Device from the Playback
parameters and 1. Acoustic Grand Piano from the Instrument parameters.
When I load a midi file (created by Lilypond) it plays with no audio
although the level meters on the track do indicate it's getting some
kind of signal.
What am I missing? And, does Qsynth need to be running at all?
Many thanks,
Peter

Hi!
First off, this is from memory of RoseGarden 9.x, I dont have it here now.
Please read with salt. :-)
1: If your using the internal synth in rosegarden, then you need to patch
the audio outputs of rosegarden to
the system playbacks, and it should all work.
2: If your using an external synth, (QSynth), you need to patch the MIDI
from RoseGarden to QSynth, and the
Audio from QSynth to the system playbacks.
I think your attempting #2, which would mean that if you patch the MIDI to
QSynth you migth be in buisness..?
Let me know.. Cheers, -Harry

Hi Harry,
1: If your using the internal synth in rosegarden, then you need to
patch the audio outputs of rosegarden to
the system playbacks, and it should all work.
I don't particularly need or want to use qsynth but thought it was
compulsory to enable audio to be produced so it's good to know that
option 1 should also work, with Rosegarden's internal synths.
Unfortunately, I cannot get it to work even after connecting the audio
ins and outs.
2: If your using an external synth, (QSynth), you need to patch the
MIDI from RoseGarden to QSynth, and the
Audio from QSynth to the system playbacks.
Unfortunately, this does not work either.
I think your attempting #2, which would mean that if you patch the
MIDI to QSynth you migth be in buisness..?
Let me know.. Cheers, -Harry
Not quite sure what I should try next.
Best,
Peter

Try this:
In track parameters (usually on the right of the main window) under the
"playback parameters" sub heading,
"device" should say "internal synth" (or similar) for Rosegarden to
generate
audio, and hence that's #1.
However I think you have "General Midi Device" selected there (hence #2),
and you need to make sure that
QSynth is recieving notes (in the QSynth GUI on the bottom there's a tab,
usually called "engine" or so. the green light
next to that should flash each time it recieves a MIDI command. (To test,
hook it up to a MIDI keyboard. )
Next: Connecting MIDI cables. In the "ALSA" tab of QJackCtl, expand the
rosegarden entry, and look for a port named
the same as your track inside rosegarden. Connect this to QSynths input. It
should be that simple i think...
Cheers, -Harry
PS: I would download RoseGarden and be able to try this, but its a 170 Mb
download for me (QT and all that..) so
Ill pass for a while I think!

My choices are "Audio", "Synth Plugin" and "General Midi

chose "General Midi Device".

QSynth 0.3.4 does not have such a meter; there is an "Output Peak Meter
Level" though but it remains inactive. (Don't have a midi keyboard so
can't do more tests.)

Ah, it seems QSynth might be the problem - it's not listed in the "ALSA"
tab. Timidity is though...
Any ideas?
Thanks again,
Peter

QSynth also supports JACK MIDI, (Check the "MIDI" tab in QJackCtl, see if
QSynth is listed there..)
Click "Setup" in QSynth, go trough the tabs, look for "MIDI Engine" or
MIDI
driver, and change the drop down box
to say ALSA instead of JACK.
That should solve it... >

Ah, wonderful. Now it's working. Many, many thanks.

Use a virtual MIDI keyboard such as vkeybd.

I'm using an old RG, so this might not apply to you, but here I have
to open the Manage Midi Devices menu and associate the synth input
port of Qsynth to General Midi Device in the "Play devices" section.
And yes, QSynth does have to be running.

This may be the problem. Qsynth does not show up here - only Timidity.
