CONST_DMUS_PC_FLAGS

Members of the CONST_DMUS_PC_FLAGS enumeration are used in the DMUS_PORTCAPS type to describe miscellaneous capabilities of the port.

End Enum

DMUS_PC_DIRECTSOUND

The port supports streaming wave data to DirectSound.

DMUS_PC_DLS

The port supports DLS Level 1 sample collections.

DMUS_PC_EXTERNAL

This port connects to devices outside of the host—for example, devices connected over an external MIDI port such as the MPU-401.

DMUS_PC_GMINHARDWARE

The synthesizer has its own GM instrument set, so GM instruments do not need to be downloaded.

DMUS_PC_GSINHARDWARE

This port contains the Roland GS sound set in hardware.

DMUS_PC_MEMORYSIZEFIXED

Memory available for DLS instruments cannot be adjusted.

DMUS_PC_SHAREABLE

More than one port can be created that uses the same range of channel groups on the device. Unless this bit is set, the port can be opened only in exclusive mode. In exclusive mode, an attempt to create a port fails unless free channel groups are available to assign to the create request.

DMUS_PC_SOFTWARESYNTH

The port is a software synthesizer.

DMUS_PC_SYSTEMMEMORY

The port is using system memory, and the amount is therefore limited only by the available system memory. This constant is used in DMUS_PORTCAPS.lMemorysize, not lFlags.

DMUS_PC_XGINHARDWARE

The port contains the Yamaha XG extensions in hardware.
