[fluid-dev] FluidSynth 1.0.9 release (was Re: Patch for bad MIDI timing (with large buffer sizes))

[Josh Green]

Hello David,

First off I'd like to say, thanks for your work in this area of
FluidSynth.  Its been a long time wish of mine to be able to render MIDI
files to audio, in a faster than realtime fashion and with the same
output every time.  This patch looks like the right direction to realize
this.

Personally I don't think we should worry about Mac OS 9 anymore.  I'm
not even sure the current FluidSynth works on Mac OS 9.  If someone out
there is using Mac OS 9 with FluidSynth, please speak up.

It seems like handling this properly would mean waiting for all voices
to terminate after the last MIDI note, plus some extra time for reverb.

A FluidSynth release is long overdue.  I already let the tentative date
of March 9th slip.  I'm buried in work right now, so I've had very
little time to put into any free software projects.

This patch seems like a pretty fundamental change, though good one.  Its
tempting to try and include it in 1.0.9.  If there was a build time or
runtime option to select this new timing source, that would be ideal.

Cheers.
