Check into some midi specs or BIAB/RB user guides and read about MSB and LSB (Most Significant Byte and Least Significant Byte). These can be designated by using Change Control 0 (CC0) for MSB and Change Control 32 (CC32) for LSB. These 2 together select the patch bank on your synth.

Then you use a Program Change number to select a particular patch on that bank.

As an example, the 3rd bank out of 10 patch banks on my Motif Rack is designated as MSB=63, LSB=2. You find this in the midi data list documents for your particular synth.

Then if I add Program Change=4 (PC=4), I've selected the 4th patch from that bank.

So the complete instructions in the midi data events log for a particular track in your DAW to change to this patch would show the following 3 lines (each listed separately):

CC0=63
CC32=2
PC=4
