The SYNTH_PORTPARAMS structure contains the configuration parameters for a DirectMusic port, which is a DirectMusic term for a device that sends or receives music data. (In KS terminology, a DirectMusic port does not correspond to a DMus port driver. It corresponds to a render or capture pin on a DirectMusic filter.)
Specifies which of the SYNTH_PORTPARAMS structure members contain valid data. This member is a bitfield whose value is either zero or the bitwise OR of one or more of the following flag bits:
The Voices field is valid.
The ChannelGroups field is valid.
The AudioChannels field is valid.
The SampleRate field is valid.
The EffectsFlags flag is valid.
The Share field is valid.
Specifies the maximum number of simultaneous voices that the application wishes to play on this port.
Specifies the number of channel groups requested for this port. Each channel group contains 16 channels.
Specifies the number of audio channels.
Specifies the number of samples per second for the audio data produced by the port.
Specifies the type of effects produced for audio output from this port. This member is a bitfield whose value is either zero or the bitwise OR of one or more of the following flag bits:
Reverb is enabled.
Chorus effect is enabled.
Delay effect is enabled.
If no effects are enabled, this member is set to SYNTH_EFFECT_NONE, which is zero.
Specifies whether the port's channel groups are shared. When this member is TRUE, all ports use the channel groups assigned to this port. When this member is FALSE, the port is opened in exclusive mode and the use of the same channel groups by other ports is not allowed.
A KSPROPERTY_SYNTH_PORTPARAMETERS get-property request uses the SYNTH_PORTPARAMS structure for both its property descriptor and its property value.
