Re: [Rosegarden-user] no sound with timidity

[David Tisdell]

Hi Stefan,

I always use ZynAddSubfx as I don't get how to work with Timidity. I 
like the sounds and find it easy to work with.

Dear community,
since 2 days I hear nothing, when I use the timidity sythesicer in 
combination with the rosegarden sequencer.

First I start midi with

modprobe snd-seq-device 
modprobe snd-seq-midi 
modprobe snd-seq-oss 
modprobe snd-seq-midi-event 
modprobe snd-seq 
timidity -iA -B2,8 -Os1l -s 44100 

Then I start rosegarden.
When I type aconnect -i iget:

client 0: 'System' [Typ=Kernel]
0 'Timer   '
1 'Announce'
Client 14: 'Midi Through' [Typ=Kernel]
0 'Midi Through Port-0'
Client 24: 'UM-1' [Typ=Kernel]
0 'UM-1 MIDI 1 '
Client 130: 'rosegarden' [Typ=User]
1 'sync out'
2 'external controller'
3 'out 1 - General MIDI Device'

And for aconnect -o I get:
Client 14: 'Midi Through' [Typ=Kernel]
0 'Midi Through Port-0'
Client 24: 'UM-1' [Typ=Kernel]
0 'UM-1 MIDI 1 '
Client 128: 'TiMidity' [Typ=User]
0 'TiMidity port 0 '
1 'TiMidity port 1 '
2 'TiMidity port 2 '
3 'TiMidity port 3 '
Client 129: 'TiMidity' [Typ=User]
0 'TiMidity port 0 '
1 'TiMidity port 1 '
2 'TiMidity port 2 '
3 'TiMidity port 3 '
Client 130: 'rosegarden' [Typ=User]
0 'record in   '
2 'external controller'
But when I type, e.g. aconnect 130:3 129:0 I can't get sound. I also 
tried it with all the other timidity-ports, bu without sucess.
The only way to get sound is to use one of the dssi-plugins (e.g. 
hexter).
I should mention that I use version 10.02 of rosegarden, on a xubuntu 
maverick meerkat machine.

It seems like the most likely explanation here is that TiMidity doesn't have 
access to the audio hardware, and isn't producing sound.

If your distro boots up with TiMidity running by default, as Ubuntu does, then 
I've found that the TiMidity process started by the init scripts frequently 
loses access to the audio hardware somewhere along the way.  It's best to kill 
that off and run TiMidity by hand.  I think the syntax you want is:

  timidity -iA -Oj -D

Since you're getting sound out of synth plugins, you should definitely be able 
to get sound out of QSynth, if not TiMidity.
