Now that I've got MidiPorts visible, I can run SqueekySynth, and do a
direct comparison with BeOS. It's not that great. (:-()
I've been using Squeeky in BeOS for quite a while now, and it's pretty
snappy. There is a tiny latency, I guess, but it's responsive enough
for fast playing.
On Haiku OTOH, the latency is an unmanageable half-second! This means
that I can't currently use Haiku for a lot of what I use BeOS for, so
I'd very much like to see if I (or someone) can fix it.
It looks pretty certain that the lag is in the audio output chain
rather than fluidsynth (Squeeky has its own copy), as Squeeky has
a 'VU meter' that shows the generated audio, and this is as fast
as in BeOS, but the sound lags the display by that half-second.
This isn't an OSS problem, is it? That's what the laptop has to use.
I'll do some digging if anyone can give me some idea how. I have no
clue about debugging the audio chain.
Cheers,
