Noteedit is only looking for the OSS sequencer (apparently something is
not right with the underlying Tse3 library - I have to look at that at
some point) and the device file for it is missing as udev does not
create it. 

You could do this (as root) to test:
  cd /dev
  ./MAKEDEV sequencer
  chown sequencer YOUR_ACCOUNT_NAME

After this you should be able to restart noteedit and it will (should?)
find the oss sequencer device. 

You could move the device node to /etc/udev/devices so that it will be
recreated on reboot:
  mv /dev/sequencer /etc/udev/devices/
If you reboot the device should be recreated and should have the right
permissions after you login (at least that happens in my tests).
