MEQ band links to continous controllers (P2CC)
Each band of the MEQ is assigned a parameter number. This number is used as
an offset into the P2CC table. The value of an entry in the P2CC may be 0
through 99. When the byte is 0, the parameter is not linked to a continuous
controller. Values 1 - 99 correspond to continuous controllers 1 - 99. The
following table lists the MEQ parameter number assignments and shows the
correspondence between a byte in the P2CC and a MEQ parameter.
