# sendProgramChange(_:onChannel:)

Sends MIDI Program Change and Bank Select events to the instrument.

```
func sendProgramChange(_ program: UInt8, onChannel channel: UInt8)
```

## Parameters

`program`

The program (preset) number within the bank to load. The valid range is `0` to `127`.

`channel`

The channel number to send the event to. The valid range is `0` to `15`.

## Discussion

The system loads the instrument from the bank that was previously set by the MIDI “Bank Select” controller messages (0 and 31). The system uses bank `0` if not previously set.
