Member Function Documentation

◆ open()

int Scumm::IMuseDriver_Amiga::open ( )
overridevirtual

Open the midi driver.

Returns
0 if successful, otherwise an error code.

Implements MidiDriver.

◆ isOpen()

bool Scumm::IMuseDriver_Amiga::isOpen ( ) const
inlineoverridevirtual

Check whether the midi driver has already been opened.

Implements MidiDriver.

◆ close()

void Scumm::IMuseDriver_Amiga::close ( )
overridevirtual

Close the midi driver.

Implements MidiDriver.

◆ send()

void Scumm::IMuseDriver_Amiga::send ( uint32  b)
overridevirtual

Output a packed midi command to the midi stream. The 'lowest' byte (i.e. b & 0xFF) is the status code, then come (if used) the first and second opcode.

Implements MidiDriver_BASE.

◆ getBaseTempo()

uint32 Scumm::IMuseDriver_Amiga::getBaseTempo ( )
overridevirtual

The time in microseconds between invocations of the timer callback.

Implements MidiDriver.
