At the moment I also have an Audigy LS (5.1) which seems to have
similar problems to the Audigy 2 ZS.

The 25MB piano soundfont is here:
http://www.wstco.com/pianosounds/freesoundfont.htm
Please note the author Warren has told me his soundfont is not re-distributable.

ALSA soundfont loading:  asfxload WST25FStein_00Aug14.SF2
ALSA OSS-mode soundfont loading:  sfxload WST25FStein_00Aug14.SF2

Sample MIDI files for piano: http://members.aol.com/sdrodrian/

 $ aplaymidi -l

  62:0    Midi Through                     Midi Through Port-0
  64:0    Audigy MPU-401 (UART) - Rawmidi  Audigy MPU-401 (UART)

  74:0    Virtual Raw MIDI 1-2             VirMIDI 1-2
  75:0    Virtual Raw MIDI 1-3             VirMIDI 1-3

 $ aplaymidi -p 65:0 midi_music_file.mid

An even better test would be to do some experiments on an Audigy using
Rosegarden 4 0.9.8 for MIDI playback, JACK audio, etc

I hope you will add MIDI support; I think it would be a great improvement.
