SYNTHVOICEPRIORITY_INSTANCE structure (dmusprop.h)
The SYNTHVOICEPRIORITY_INSTANCE structure identifies a voice in a MIDI synthesizer by specifying the voice's channel group (set of 16 MIDI channels) and its channel number within that group.
Syntax
typedef struct _SYNTHVOICEPRIORITY_INSTANCE {
DWORD ChannelGroup;
DWORD Channel;
} SYNTHVOICEPRIORITY_INSTANCE, *PSYNTHVOICEPRIORITY_INSTANCE;
Members
ChannelGroup
Specifies the channel group that the voice belongs to. Channel groups are numbered beginning at zero. Each channel group contains 16 channels.
Channel
Specifies the channel that the voice is on. This member contains a channel number in the range 0 through 15. It identifies a channel in the channel group.
Remarks
The KSPROPERTY_SYNTH_VOICEPRIORITY property request uses the SYNTHVOICEPRIORITY_INSTANCE structure for its property descriptor. The structure specifies which voice gets priority when the miniport driver needs to bump voices from the cache.
