[linux-audio-user] Rosegarden not playing MIDI events

[Christoph Eckert]

Hi,


I recently installed Gentoo on my box, and I'm really amazed 
about the very recent software Gentoo has to offer.

I tried to do some MIDI sequencing on my former Mandrake box, 
but I didn't get all things to work.

So, I hoped I could do some sequencing on the Gentoo box.

Unfortunately MusE still freezes as soon as I press the play 
button without any error message, so I installed Rosegarden.

I connected my MIDI masterkeybord to my notebook using a 
MIDI2USB adapter (UM-1S).

In Rosegarden, I can see the incoming events in the transport 
panel resp. the events view on each track.

MIDI through just works fine, I can play my external equipment 
connecting both the masterkeyboard and my devices to the 
computer.

I then have drawn a one bar segment and placed some drum notes 
in it. I can hear my expander playing the base and snare drum 
as soon as I paint a note or as soon as I klick on one.

Unfotunately, Rosegarden does not play the events.

As soon as I press the play button, the transport panel 
shortly shows that controller data is being sent, but it does 
not play my drum events, and the pointer does not cross my 
segments from left to the right.

I'm really sure I simply cannot see the wood for the trees, so 
any hint would be really great, even if it were a RTFM - as 
soon as it includes a link to the correct document ;-) .

But I'm kidding, I read the included manual, the FAQ and asked 
Google without finding the needed information.

I wonder because in Rosegarden there are no pointers to be set 
on the left and right end of the wished playback area; am I 
missing them, or does Rosegarden not need them?

Maybe that's the wee small thing I'm missing?


Any helpful hint could turn me into a glad linux audio user, 
so sorry if it is a really silly question ;-) .

My system includes:


* Kernel 2.6.7-gentoo-r6
* ALSA Driver Version 1.0.4
* Rosegarden-4.0.9.8


 Many thanks & best regards
