IMiniportDMus

The IMiniportDMus interface is the primary interface for a DMus miniport driver for a DirectMusic synthesizer device. In Windows 98/Me and in Windows 2000 and later, the DMus port driver communicates with the miniport driver through this interface. The adapter driver creates the DMus miniport object and passes the object's IMiniportDMus interface pointer to the port driver's IPort::Init method (see the code example in Subdevice Creation). IMiniportDMus inherits from the IMiniport interface.

An adapter driver forms a miniport/port driver pair by binding an IMiniportDMus object to an IPortDMus object. The PortCls system driver registers this pair with the system as a DirectMusic filter (see MIDI and DirectMusic Filters).

The IMiniportDMus interface provides methods for initializing the miniport driver, for creating a new DirectMusic stream, and for notifying the miniport driver of an interrupt service request.

In addition to the methods that IMiniportDMus inherits from the IMiniport interface, IMiniportDMus supports the following methods:

IMiniportDMus::Init

IMiniportDMus::NewStream

IMiniportDMus::Service
