Hi, I'm mighty confused by the following code. When I run this in one project it works fine, when I run it in another one it crashes.
Both projects appear identical in terms of frameworks CoreAudio, CoreFoundation, CoreMIDI, AudioToolbox, Both target iOS 6 iPad Simulator.
Though clearly something differs.
Fails with:

libc++abi.dylib: terminate called throwing an exception
Any ideas?
The code....
The following code is instantiated within a view controller...
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSLog(@"viewDidLoad" );
_bMAudio = [[BMAudio alloc]init];
[_bMAudio midiTest];
}
------------------------------------
#import "BMAudio.h"
@interface BMAudio ()
@end
@implementation BMAudio
- (id) init{
if (self = [super init]) {
}
return (self);
}
static void MyMIDIReadProc(const MIDIPacketList *pktlist,
void *refCon,
void *connRefCon) {
NSLog(@"test ");
}
void MyMIDINotifyProc (const MIDINotification *message, void *refCon) {
printf("MIDI Notify, messageId=%ld,", message->messageID);
}
-(void) midiTest {
OSStatus result = noErr;
// Create a client
MIDIClientRef virtualMidi;
result = MIDIClientCreate(CFSTR("Virtual Client"),
MyMIDINotifyProc,
NULL,
&virtualMidi);
NSAssert( result == noErr, @"MIDIClientCreate failed. Error code: %d '%.4s'", (int) result, (const char *)&result);
// Create an endpoint
MIDIEndpointRef virtualEndpoint;
result = MIDIDestinationCreate(virtualMidi, (CFStringRef)@"Virtual Destination", MyMIDIReadProc, (__bridge void *)(self), &virtualEndpoint);
NSAssert( result == noErr, @"MIDIDestinationCreate failed. Error code: %d '%.4s'", (int) result, (const char *)&result);
}
@end
