I did it, it was pointers to address that worked. And oddly the gcc
compiler complained about the dereferencing with warnings. Is there a
better way to unwrap the data? Well, anyway it does give the proper
midi note and velocity data. I prefer objective C over C.
-(id)tableView: (NSTableView *)tableView objectValueForTableColumn:
(NSTableColumn *)tableColumn row: (int)row
{
MusicTrack track = [[[[NSApp mainWindow] windowController]
document] getSelectedTrack];
NSArray *events = [[[[NSApp mainWindow] windowController]
document]getMidiEventsForTrack: track];
MidiEvent *me = [events objectAtIndex: row];
MidiEventInfo midiInfo = [me info];
MusicTimeStamp mts = midiInfo.stamp;
MusicEventType met = midiInfo.type;
UInt32 size = midiInfo.size;
int i;
void *data1 = midiInfo.data;
UInt8 *p,*q, *r;
r = &data1[0];
p = &data1[1];
q = &data1[2];
if([[tableColumn identifier] isEqualToString: @"time"])
{
return [NSNumber numberWithFloat: mts];
}
else if ([[tableColumn identifier] isEqualToString: @"type"])
{
return [NSNumber numberWithInt: *r];
}
else if ([[tableColumn identifier] isEqualToString: @"value"])
{
return [NSNumber numberWithInt: *p];
}
else if ([[tableColumn identifier] isEqualToString: @"velocity"])
{
return [NSNumber numberWithInt: *q];
}
return 0;
}
