# MIDISendUMPSysex8(_:)

Asynchronously sends a single universal MIDI packet (UMP) system-exclusive (SysEx) event with an 8-bit message.

```
func MIDISendUMPSysex8(_ umpRequest: UnsafeMutablePointer<MIDISysexSendRequestUMP>) -> OSStatus
```

## Parameters

`umpRequest`

Contains the destination and a pointer to the MIDI data to send.

## Return Value

An `OSStatus` result code.

## Discussion

The request’s [`data`](/documentation/CoreMIDI/MIDISysexSendRequest/data) needs to point to a single MIDI SysEx 8-bit message, or portion thereof.
