Hello,
Here's a code fragment that I am (incorrectly) assuming should be
populating a MusicTrack with note messages. Unfortunately, it isn't,
as far as I can tell, doing anything. (The note messages are never
added; iterating over the MusicTrack reveals no contents). What am I
doing wrong? (I'm using Panther, if that matters.)
---snip---
UInt8 notevals[16] = {
60,64,67,72,67,64,60,55,
60,63,68,72,68,63,60,56
};
MusicSequence mySeq;
MusicTrack myTrack;
MusicPlayer myPlayer;
MusicTimeStamp time = 0.0f;
float duration = (float)(1/16);
int i = 0;
verify_noerr(NewMusicSequence(&mySeq));
verify_noerr(MusicSequenceNewTrack(mySeq, &myTrack));
for (i = 0; i < 64; i++) {
MIDINoteMessage theMsg;
theMsg.channel = 1;
theMsg.note = notevals[i];
theMsg.velocity = 120;
theMsg.reserved = 0;
theMsg.duration = 0.125f;
verify_noerr(MusicTrackNewMIDINoteEvent(myTrack, time,
&theMsg));
time = time + 0.125f;
}
verify_noerr(NewMusicPlayer(&myPlayer));
verify_noerr(MusicPlayerSetSequence(myPlayer, mySeq));
---snip---
thanks,
wb
