23d9812273 loader-initialized global plugin API: 
struct plugin_api *rb is declared in PLUGIN_HEADER, and pointed to by
__header.api

the loader uses this pointer to initialize rb before calling entry_point

entry_point is no longer passed a pointer to the plugin API

all plugins, and pluginlib functions, are modified to refer to the
global rb

pluginlib functions which only served to copy the API pointer are
removed

4c43f7be0a Rearrange the main synth loop a little and move some tests around for a ~5% speedup on c200, increase the output buffer size to make skips less likely, playback of simple midi files should now be mostly skip free on pp based players

7ef2a053b8 Turns out that using likely in the loop condition gives a nice little speedup to so let's do it.

1284c127f8 Introduce likely() and unlikely() macros, use to give gcc hints about which branch is likely to be taken in a conditional, use them in the midi player for a small speedup, use instead of similar EXPECT macros in tremor and use in mpegplayer

0fd4c2e455 Rearrange logic in the synthVoice loop to do less tests and remove need of a struct member for a small speedup, move some memory lookups out of the loop for a small speedup, further cosmetic changes to the synthVoice function. Change isUsed to a bool for clearer logic and also a tiny speedup

cd963d84ca MIDI: Allow seeking forward and backward using the left/right keys. Currently seeks in 5 second 
increments, but this can be set to any amount. Also implemented a counter for playing time, which can 
pretty easily be used to determine the length of the file, in seconds, before playing it. The time 
isn't displayed anywhere right now, but all this can be useful if this thing is turned into a codec, or 
at least gets a nice UI.

loop optimization patch. I hope committing it does not cause problems.

28b5afd05a Optimize synth code by pre-computing the volume scaling for each note. 
Scaling is now calculated once per MIDI event at the most, instead of
once per sample. Increase voice ramping speed, increase number of
active voices a little.

b2f1b5dd18 ---------------------------------------------------------------------- 
Added Karl Kurbjun's sound output patch, cleaned up some output.
Main file is now midiplay.c, midi2wav is still in there for anyone who
wants it. Set sampling rate to 22k, and increased note decay time.
Reduced number of concurrent active voices and made new notes replace
used voices if none are available. This makes lag less apparent.
I really hope this wont go red. (turns around and runs)

2ed84ec2ca The synthVoice() function declaration was wrong (caused a warning). And because of that GCC didn't notice the error on line 390: synthVoice(currentVoice). 
In revision 1.4 Steven made currentVoice global, so the function declaration should be: synthVoice(void), wich fixes a warning. And the call should be just synthVoice() wich fixes a hidden error.

Hope I saw this right... please correct me if this isn't the way you ment is Seven.
