[PlanetCCRMA] Rosegarden and Jack

[Mark Knecht]

Eric,
   Sign up and participate on the Rosegarden-Users list. All three developers are very involved and answer questions quickly.

   I've had a bit of trouble with RG audio also, but I actually use Ardour to record the audio that RG creates, so I haven't had to get this sorted out.

   I look forward to seeing you there.

Cheers,
Mark

  Hi all, 

  First I must say that PlanetCCRMA is an awsome project! I just now have a dream machine for sound! Thanx and vive Linux! 

  Ok, here 's my problem... 

  I can't get any sound out of rosegarden... But, I can connect alsaplayer to jack (alsaplayer -o jack) and it plays fine cd's and other formats. 

  When I start rosegardensequenser from a shell I get the right stuff :

  Rosegarden AlsaDriver - alsa-lib version 0.9.0rc6 

    ALSA Client information:

  AlsaDriver::getMappedComposition - got unrecognised MIDI event type = 67 


------------------------------------------------------------------------------


  Just that ''got unrecognised MIDI event type = 67'' message, don't know what that is. 

  I can play the midi file generated by rosegarden with timidity or ecasound without any problems. I just can't see why I can't get a sound out of rosegarden! It must be too simple so I don't see it! :) 

  My sound card is soundblaster live, I start jack with this command : 

  jackstart -d alsa -d hw -r 44100 

  Run everything as root. 

  Any ideas? 

  Thank a lot, 

  Eric,
