NO, I'm not saying that. What I'm doing is I'm using the same CC# for all the delay blocks, another CC# for reverb, another for chorus, etc. to bypass the effect. So when I am in stomp box/effects mode and step on the delay bypass button, it bypasses any and all delays in the preset.
Regarding CC# for channel changing, The X-15 has 2 modes I use, channel changing, (this assigns the 10 buttons to change from preset to preset), Those are different CC numbers. Each number is used for a different task. The other mode is effects mode, (step on a button to change to effects mode), where it turns the board into a stomp box, (the 10 buttons become individual effects pedal buttons).
Here are a few that the X-15 uses
PAD #EFFECT MIDI CONTROLLER #
1 EXCITER 70
2 COMPRESSOR 71
3 DISTORTION 72
4 EQUALIZER 73
5 EXPANDER/NOISE GATE 74
6 REVERB 75
7 DELAY 76
8 PITCH TRANSPOSER 77
9 FLANGE/CHORUS 78
10 SPECIAL EFFECTS 79
11 EXPRESSION CONTROLLER 11
12 FOOT CONTROLLER X-15 LEFT PEDAL 4
There are many more CC# to assign ranging from 1 to over 100.
