HRESULT InsertTool(
  IDirectMusicTool* pTool,
  DWORD* pdwPChannels,
  DWORD cPChannels,
  LONG lIndex
);

pTool
Tool to insert.
pdwPChannels
Address of an array of PChannels on which the tool accepts messages. If the tool accepts messages on all PChannels, pass NULL.
cPChannels
Count of how many PChannels are pointed to by pdwPChannels. Ignored if pdwPChannels is NULL.
lIndex
Position at which to place the tool. This is a zero-based index from either the start or (if it is negative) the end of the current tool list. If lIndex is out of range, the tool is placed at the beginning or end of the list. To place a tool at the end of the list, use a number for lIndex that is larger than the number of tools in the current tool list.
