Question on sequencer synth driver

["Ville Syrjälä" <syrjala@sci.fi>]

I'm still struggling with my MikMod driver, and since no one has answered 
my previous mails, I've been trying to figure it out myself. Maybe I'm in
Jaroslav's procmailrc or something :( Takashi can you take a look?

My problem is that events get delivered but I don't get any sound. I've
concluded that snd_gus_synth_event_input() get's called and it in turn
calls snd_gus_sample_event(). And in that function the problem arises. The
for-loop tests for v->use for each voice. And in my case v->use is never
set. The 'use' field is set in snd_gf1_alloc_voice() which is called from
snd_gus_synth_use(). Is's called for as many voices as the subscriber has
requested. But the voices field in snd_seq_port_subscribe_t can't be set
because there is no function to do so. So I think I need 
snd_seq_port_subscribe_set_voices(). To continue my testing I added that
function to my local copy of alsa-lib. But I was disappointed again. Now
it seems that snd_gus_synth_use() doesn't even get called when I
connect my client to the synth. It's registered as the 'use' port
callback, and if I'm not mistaken it should get called whenever a client
connects.

Summary:
I think snd_subscribe_{set,get}_voices() are needed.
Why doesn't snd_gus_synth_use() get called when my client connects to it?
