[LAD] More midi related questions

[gene heskett]

Greetings all;

Still trying to sort reasons why a java app can't access the midi synth in 
my sound card.

From an aplaymidi -l:
[root at coyote modprobe.d]# aplaymidi -l
 Port    Client name                      Port name
 14:0    Midi Through                     Midi Through Port-0
 16:0    SB Audigy 2 Value [SB0400]       Audigy MPU-401 (UART)
 16:32   SB Audigy 2 Value [SB0400]       Audigy MPU-401 #2
 17:0    Emu10k1 WaveTable                Emu10k1 Port 0
 17:1    Emu10k1 WaveTable                Emu10k1 Port 1
 17:2    Emu10k1 WaveTable                Emu10k1 Port 2
 17:3    Emu10k1 WaveTable                Emu10k1 Port 3

Can I make the inference that a .mid file sent to 14:0 should find its way 
to one of the 17:n ports?  It only works if I -s to 17:0(thru 3)

Java, by its scanning methods, finds a huge list of ports, but only the 
semi-broken, internal to java, synth actually makes a noise.

If I switch to amidi -l, the list is a bit shorter:
Dir Device    Name
IO  hw:0,0    Audigy MPU-401 (UART)
IO  hw:0,1    Audigy MPU-401 #2
IO  hw:0,2    Emu10k1 Synth MIDI (16 subdevices)
IO  hw:0,3    Emu10k1 Synth MIDI (16 subdevices)

but sending a midi file to the latter pair, while taking the normal play 
time for the file, is also silent.  KMix gain is turned up quite a ways.

From the lengthy output of amixer contents:
numid=7,iface=MIXER,name='Synth Playback Volume'
  ; type=INTEGER,access=rw---R--,values=2,min=0,max=100,step=0
  : values=72,72
  | dBscale-min=-40.00dB,step=0.40dB,mute=1

But since aplaymidi works, I'm confused, does mute=1 mean it is live, not 
off?

When java scans for synths, I get at the end of the listing, a 
realtime_synth as device #68 in base 0.  But I haven't a clue if that is 
the audigy2's synths, but its silent in any event.

The target here is to somehow link this so the java system can actually use 
the hardware synths in an Audigy2 Value card.  But any attempt to send to a 
(hw0:0) thru (hw0:3) path is silent, however aplaymidi always uses the same 
amount of time to send the file.

Suggestions of what to check next?, please as I am lost in whatever 
translations actually take place because there seems to be 2 different 
methods of accessing a device and I can't find how they correlate.

Thank you.

Cheers, Gene
