HRESULT AssignPChannelBlock( DWORD dwBlockNum, IDirectMusicPort* pPort, DWORD dwGroup );
Block number, in which 0 represents channels 0 through 15, 1 represents channels 16 through 31, and so on.

Channel group on the port. Must be 1 or greater.
If the method succeeds, the return value is S_OK or S_FALSE (see Remarks).
If it fails, the method can return one of the error values shown in the following table.
This method must be called when a port has been added to a performance, except when the default port has been added by passing NULL to IDirectMusicPerformance8::AddPort.
The method returns S_FALSE if dwGroup is out of the range of the port. The channels have been assigned, but the port cannot play this group.
The method returns E_INVALIDARG if the port has not been added to the performance through a call to the IDirectMusicPerformance8::AddPort method.
