Use this type to collect incoming SysEx 7 messages from a MidiEndpointConnection, and get them as blocks of bytes.
Constructors
| Constructor |
Description |
MidiSystemExclusiveReceiver(sourceConnection, sourceGroup, maximumBytesPerEvent) |
Creates a receiver for one connection and group. maximumBytesPerEvent is the most bytes it collects before it raises an event |
Events
| Event |
Description |
BytesReceived |
Raised when a complete SysEx message is ready, or when the collected bytes reach maximumBytesPerEvent |
Methods
| Method |
Description |
Start() |
Starts receiving. Returns true if it worked |
Stop() |
Stops receiving, and passes on any bytes it’s holding. That may raise more BytesReceived events before it returns |
Properties
| Property |
Description |
IsReceiving |
True while it’s receiving |
CountBytesReceived |
The total number of bytes received |
CountMessagesReceived |
The total number of complete SysEx messages received |
maximumBytesPerEvent trades memory for how often events are raised. A smaller value means more frequent events. A larger value means fewer events, but more memory held between them.
Samples
These samples receive a System Exclusive message and write it to a .syx file. They replace the WinMM work of handling MIM_LONGDATA, preparing and queuing MIDIHDR buffers again and again, and putting back together a message that arrived across several of them.
