u32 index;
The index parameter is set by the AX library.
The AX library manages an array of AXVPB structures equal in number to AX_MAX_VOICES or the maximum number of voices specified when the AX library was initialized. The index parameter represents the index of a given voice within this array and does not change for the entire AX session.
When creating an abstraction layer for AX voices, you are encouraged to implement a parallel array, and use the index parameter for fast referencing of voices.
Do not modify this parameter.
