About new development, there is an improvement to fluid that I had  
worked on two years ago in a private branch that I think should be  
integrated inside the main code base. I don't know if it should be  
integrated into 1.x or 2.x, because it changes the API a bit.

The bug is with the sequencer : in short, the sequencer uses the  
computer clock to trigger its sequenced events, whereas the audio  
buffers are requested and created by the soundcard when it needs them  
which may be ahead of realtime, resulting in events not being  
triggered at the right moment in the audio stream. The fact is that in  
real life, audio cards do request audio buffers ahead of time,  
sometimes a lot ahead, in bulk (like 16 buffers at once), thus not  
leaving time for the sequencer to trigger its events at the right  
moment in the audio stream.
I have fixed this by:
- making the sequencer use the audio stream as a clock
- calling the sequencer from the synth audio callback so that  
sequenced events are inserted in the audio buffer right before the  
audio is rendered
This implied a small change in the API because now the sequencer  
depends on the synth to get its clock (which was not the case before).

How should I proceed to include it in the main code base ?
