Hi,

I think this one's mine. If things were working fine with -Ma but were
broken if you specified -Mhw:1,0 then this bug is now fixed in cvs.

Are you having problems with -Ma too?

Cheers,
Andrés

Thanks for having a look. Seems not related to MIDI. Are you having
the same problems if you don't use portmidi instead of alsa MIDI?

Cheers,
Andrés

Hi,

These are the changes from 5.11 in rtalsa.c:

http://csound.cvs.sourceforge.net/viewvc/csound/csound5/InOut/rtalsa.c?r1=1.29&r2=1.37

I only see one change that might have triggered this, which is line 322.

All the rest seem related to MIDI or just cosmetic...

Any chance there has been any changes in your alsa configuration?

The old parser is a bit broken in this release, I get the feeling it's
better to use the new parser mostly.

Cheers,
Andrés

Hi,

You can try specifying "plughw" and "default" as the alsa devices to
see if this might be the cause...

Cheers,
Andrés

Hi,

Great! So it seems "plughw" in your case worked better than "default".
I remember there was a discussion about this change when it was done,
but I don't remember exactly why it was done...

Cheers,
Andrés
