Arguments

p Specifies a pointer to the AXVPB structure acquired from AX by the user. This must be a valid pointer returned by AXAcquireVoice.
mode Specifies the initial mode for Aux A, Aux B, and the mute controls. This value is the bits identified by the OR logic within the following:
MIX_MODE_AUXA_PREFADER Specifies that Aux A is in pre-fader mode. If not specified, Aux A is in post-fader mode.
MIX_MODE_AUXB_PREFADER Specifies that Aux B is in pre-fader mode. If not specified, Aux B is in post-fader mode.
MIX_MODE_AUXC_PREFADER Indicates that Aux C is in pre-fader mode. If not specified, Aux C is in post-fader mode.
MIX_MODE_MUTE Indicates that input will be muted. If not specified, input will not be muted.
input Specifies the initial attenuation for input control in 0.1-dB increments (1 = 0.1 dB).
auxA Specifies the initial attenuation for Aux A control in 0.1-dB increments (1 = 0.1 dB).
auxB Specifies the initial attenuation for Aux B control in 0.1-dB increments (1 = 0.1 dB).
auxC Specifies the initial attenuation for AuxC control in 0.1-dB increments  (1 = 0.1 dB).
pan Specifies the initial value for pan control (left = 0, center = 64, right = 127).
span Specifies the initial value for span control (surround = 0, center = 64, front = 127).
fader Specifies the initial attenuation for fader control in 0.1-dB increments (1 = 0.1 dB).

Return Values

None.

Description

The MIXInitChannel function initializes a mixer channel to use on a voice. After successfully acquiring a voice from AX, call the MIXInitChannel function to use the mixer for that voice. The MIXInitChannel function also sets all the initial settings for the input channel.
