c84461fb8f More adsr related nonsense, argh! Fix adsr related problem on some notes being stopped instead of
looped. Ramping code still not quite right, but dont want to lose this.

80b4882922 I have an iRiver again, yay! Make notes ramp down in a better way. Fix
note-off pop/click due to waveform index out of bounds access.

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.

47efba8bbf Fix file descriptor leak that would cause a hard lockup every 7 files
played. A few other cosmetic changes. please, please no red build =)

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.
