hello
i'm trying various audio softwares and i got stuck with rosegarden. i
can't figure what am i doing wrong and especially - what i am doing
right when i suddenly hear it playing my music ;)
here is what i'm doing:
1. start timidity
$ timidity -iA
Requested buffer size 32768, fragment size 8192
ALSA pcm 'default' set buffer size 32768, period size 8192 bytes
TiMidity starting in ALSA server mode
Opening sequencer port: 128:0 128:1 128:2 128:3
i know timidity is setup correctly because i can play midifiles with
it
2. start rosegarden
$ rosegarden
... loads of messages, really scary ...
on the console where i started timidity the following appears:
---------------------------------------------------------------------------
Requested buffer size 32768, fragment size 8192
ALSA pcm 'default' set buffer size 32768, period size 8192 bytes
---------------------------------------------------------------------------
3. trying it out: i enter some notes in a notation editor, set the
tracks instrument to Midi software device #1 and click the play
button. i hear nothing, the blue cursor doesn't move, on the
console the following apears:
---------------------------------------------------------------------------
rosegarden (sequence manager): ControlBlockMmapper::updateMetronomeForPlayback: muted=true
rosegarden (sequence manager): SequenceManager::play() - starting to play
AlsaDriver::stopClocks
AlsaDriver::stopClocks: ALSA time now is 0.000000000R
rosegarden (sequencer): mmapping /tmp/kde-artm//segment_87d60e0

rosegarden (sequencer): jumpToTime( 0.000000000R)
processMidiOut[0]: event is at 0.000000000R ( 0.000000000R ahead of queue time)
processMidiOut[0]: instrument 2016 -> output device 128:0
pitch: 64, velocity 100, duration 0.500000000R
AlsaDriver::startClocks
AlsaDriver::startClocks: started clocks
RosegardenSequencerApp::incrementTransportToken: incrementing to 14
rosegarden (sequencer): Sequencer status changed from 0 to 1
---------------------------------------------------------------------------
where should i look for the reasons it doesn't wanna roll?
the mystery is that sometimes it works. and i have no idea how to
recreate that state.
