6888db3240 Do not duplicate const table, make getEvent function static inline, gives about a ~1.5% speedup, put tick function in iram, ~3.5% speedup

8b6d28790e Some MIDI changes, and add a new musical plugin I'm working on... Not fully done yet, so commented out 
of SUBDIRS. (If people are against having half-baked plugins in SVN, please let me know and I will 
remove it).

26d242ae65 General housekeeping: Make plugin buffer functions take size_t * instead of int * to match the parameter type of the buffer functions called in the core. Get rid of unsafe int * <==> size_t * casting. Use ssize_t where int was used and size_t where unsigned int was used in the buffer calls to not alter signedness in the plugins. No API version change since it should only be an issue for 64-bit sim builds.

looped. Ramping code still not quite right, but dont want to lose this.

68af7bae87 Added ability to adjust the volume during playback. 
Gracefully fail if no soundset installed.
Yet more messing with the ramping code. I swear, that will be the end of
me.
Basic skipping support- skip foreward a bit if Right is pressed.

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.
