typedef void(^ | ABMIDIFilterPortMIDIReceiverBlock )(__unsafe_unretained ABPort *_Nonnull source, const MIDIPacketList *_Nonnull packetList) |
Block to handle incoming MIDI messages. | |
typedef void(^ | ABMIDIFilterPortMIDIFlushEventBlock )(__unsafe_unretained ABPort *_Nonnull source) |
Block to handle MIDI flush events. | |
typedef void(^ | ABMIDIFilterPortInstanceConnectionBlock )(ABMIDIFilterPort *_Nonnull instance) |
Block to handle instance connection or disconnection. | |
typedef void(^ ABMIDIFilterPortMIDIReceiverBlock)(__unsafe_unretained ABPort *_Nonnull source, const MIDIPacketList *_Nonnull packetList) |
Block to handle incoming MIDI messages.
Upon receiving MIDI messages, a MIDI Filter port should generate new MIDIPacketLists as required, and then send them on using ABMIDIPortSendPacketList.
Note: this will be called on the realtime MIDI receive thread, so be careful not to do anything that could cause priority inversion, like calling Objective-C, allocating memory, or holding locks.

typedef void(^ ABMIDIFilterPortMIDIFlushEventBlock)(__unsafe_unretained ABPort *_Nonnull source) |
Block to handle MIDI flush events.
See ABMIDIFilterPort's [MIDIFlushEventBlock](ABMIDIFilterPort::MIDIFlushEventBlock) documentation for details.
Note: this will be called on the realtime MIDI receive thread, so be careful not to do anything that could cause priority inversion, like calling Objective-C, allocating memory, or holding locks.

typedef void(^ ABMIDIFilterPortInstanceConnectionBlock)(ABMIDIFilterPort *_Nonnull instance) |
Block to handle instance connection or disconnection.
Use this with the multi-instance port initializer. It will be called on the main thread. You may assign a new MIDIReceiverBlock value for the new instance when this block is called, and it will replace the one you provided to the ABMIDIFilterPort initializer.
