Re: can multiple audio units be put in a single bundle?

Hi,

We have built various AU bundles with multiple components in one binary.

You just keep adding, like this:

#include <AudioUnit/AudioUnit.r>

#include <AudioUnit/AudioUnitCarbonView.r>

#define RES_ID 1100

#define COMP_SUBTYPE 'SMD2'

#define COMP_MANUF 'UHfX'

#define COMP_TYPE 'aumu'

#define VERSION VERSION_ZEBRA2

#define NAME "u-he: Zebra2"

#define DESCRIPTION "AudioModulesMD"

#define ENTRY_POINT "AudioModulesMDEntry"

#include "AUResources.r"

#define RES_ID 1150

#define COMP_SUBTYPE 'SMD3'

#define COMP_MANUF 'UHfX'

#define COMP_TYPE 'aumu'

#define VERSION VERSION_ZEBRA2

#define NAME "u-he: Zebralette"

#define DESCRIPTION "AudioModulesMD"

#define ENTRY_POINT "AudioModulesMDEntry"

#include "AUResources.r"

#define RES_ID 1200

#define COMP_SUBTYPE 'reV0'

#define COMP_MANUF 'UHfX'

#define COMP_TYPE 'aumf'

#define VERSION VERSION_ZEBRA2

#define NAME "u-he: ZRev"

#define DESCRIPTION "AudioModulesAU"

#define ENTRY_POINT "AudioModulesAUEntry"

#include "AUResources.r"

#define RES_ID 1209

#define COMP_SUBTYPE 'SMY2'

#define COMP_MANUF 'UHfX'

#define COMP_TYPE 'aumf'

#define VERSION VERSION_ZEBRA2

#define NAME "u-he: Zebrify"

#define DESCRIPTION "AudioModulesAU"

#define ENTRY_POINT "AudioModulesAUEntry"

#include “AUResources.r"

// ____________________________________________________________________________

// component resources for Audio Unit Carbon View

#define RES_ID 2000

#define COMP_TYPE 'auvw'

#define COMP_SUBTYPE 'SMD2'

#define COMP_MANUF 'UHfX'

#define VERSION VERSION_ZEBRA2

#define NAME "u-he: Zebra2"

#define DESCRIPTION "AudioModulesAUView"

#define ENTRY_POINT "AudioModulesAUViewEntry"

#include “AUResources.r"

Cheers,

- Urs

Oh, actually it's the same exact class, so my question is really how to set up a bundle with two AUs in it.

Looks like I have to keep using the .r file for compatibility with Ableton Live (possibly others). I tried two .r files (effect and instrument) but that only produced one AU. My .r file looks like:

#include <AudioUnit/AudioUnit.r>

#include "AudulusAUVersion.h"

// Note that resource IDs must be spaced 2 apart for the 'STR ' name and description
#define kAudioUnitResID_Audulus 1000

#define RES_ID kAudioUnitResID_Audulus
#define COMP_TYPE kAudioUnitType_MusicDevice
#define COMP_SUBTYPE Audulus_COMP_SUBTYPE
#define COMP_MANUF Audulus_COMP_MANF

#define VERSION kAudulusAUVersion
#define NAME "Audulus: Audulus"
#define DESCRIPTION "Audulus"
#define ENTRY_POINT "AntimatterAUEntry"

#include "AUResources.r"

How can I add a second AU to the .r file?

thanks!

You’d have to rename that class in one of the bundles. Objective-C doesn’t allow two classes with the same name to be loaded in the same process.

Usually the easiest way to do this without having to edit a bunch of source code is to use the preprocessor, e.g. in one of the targets use a prefix header that contains
#define AUViewListener AUViewListenerForInstrument
