The struct below is set up similar to the above, but because of alignment issues (e.g., the 2-byte unused2 above starts at byte 36 but in the struct below the unused2 will probably be aligned 40 bytes into the struct), we CANNOT do a single wholesale copy to move the packet data into the struct.
Also, the struct is sized to hold the maximum number of channels, while the actual data packet may contain fewer than the maximum.
