Several of the modulation source parameters are nibble-ized. The MOD 1 source is in the low nibble with a range of 0-15, while the MOD 2 source is in the high nibble with a range of 16-31. The low nibble can be programmed with SysEx using the given address that is larger than the program itself. The table below should clarify this for anyone who is setting up SysEx strings to change these mod sources. Address are listed in hex, data range in decimal.
*BE CAREFUL, the high nibble address aren't in numerical order.
