OM 6.10 beta 4 - linux

OpenMusic
#1

OM 6.10 beta 4 (.rpm, .deb) are available at the usual place.

Changes:

  • SDIF: more robust loading of libsdif.so. If no libsdif.so is found in /usr/local/lib/* or in /usr/share/openmusic/resources/*, the current LD_LIBRARY_PATH is looked up.
  • Remove unused mac/win libs from rpm - saves 20Mb in packages and 45Mb in installed OM. Why didn't i do this 2 years ago?

Please check and report back.

Thanks: Karim and fdsdb.

Hi,

I decided to test OM 6.10 beta4.deb on an ubuntu 14.04 Crouton installation over ChromeOS.
Here is a small guide, in case someone else wants to do the same.

Getting OM to work on Crouton (L)ubuntu 14.04 Trusty

  1. Download and Install SDIF-3.11.4-1_i386.deb
  2. Download and Install OM_6.10-4.deb

Errors and Fixes

Audio:

  • Problem: QjackCtl wouldn’t start up, eventually crashing OM.
  • Possibile fixes:

a)Route JACK output through CRAS (increases latency)
b)Stop CRAS, add your user to hwaudio group, then get JACK to talk directly to the hardware.

Midi:

  • Problem: alsa_seq was giving errors, hence OM was not recognizing a midi device.
  • Possibile fixes: Set correct user and permissions for /dev/snd/seq
  • Fix: sudo setfacl -m u:user:rw- /dev/snd/seq
    Alternatively modify: /etc/rc.local -> add this statement: chmod a+rw /dev/snd/seq -> restart your chroot

Configuring Qsynth (fluidsynth) in setup:
Midi Driver: alsa_seq
Midi Client: qsynth
JACK Client Name ID: qsynth
Load soundfont

Configuring JACK in setup:
Driver: alsa
Interface: cras (see above)
Midi Driver: seq

Start order, plays a role in my tests. Running
Jack->Qsynth->OM gives me no problems

Everything else seems to be working well.

Cheers
