OK, I have some more questions now.
Do I have to put in a volume/pan block into every preset that I have in order to be able to use them with one of the X-15 expression pedals?
Not necessarily. You could also attach one of your X-15 expression pedal to the main out level... however, this will affect the volume post-effects. In other words, when you lower the volume, it will also lower any reverb or delay trails. I much prefer to use a volume block and place it after the amp (not before, unless you want that volume control to also affect gain) and before reverb and delay (so that when I change the volume, the trails remain unaffected). It's very flexible.

If so, where is the best place to put the volume block so that it doesn't change the tone of the preset but instead only increases or decreases the volume? I would guess at the end of the layout but I haven't tried this yet.
Like I said above, there are many options. Before the amp block you get to change the tone and gain, whereas after the amp block, you only change the perceived output volume. Before the reverb and delay, you get to keep the trails.

When I use the modifiers, which one should I choose for the source? I couldn't get the pedal to move the volume on the modifier graph by using any of the source selections.
You probably missed a step. To assign a modifier, you need to do two things:
- Step 1: Set up a controller: Hit the I/O button, page over to CTRL, scroll down to one of the external controllers (external 1 for example), then turn the dial to enter the CC # of your X-15 pedal. If you don't know what that number is, use the "learn" function: hit the "Enter" button, and the Axe-FX will detect the CC# when you move that X-15 pedal. Once this step is completed, your X-15 expression pedal is now globally assigned to "External 1", which can now be used as a controller in any patch.
- Step 2: Assign the controller to a parameter. In this case, assigne External 1 to the volume parameter of a volume block. Edit the volume block, place the cursor on the Volume parameter, hit "Enter" to go into modifier mode, and select "External 1" as the controller. Edit your curve as needed. That's it, you're done.

I am going to have some of the same questions on the Wah too. Do I have to put in a wah block on every preset to use the 2nd expression pedal? How do I get the Wah to shut off?
Yes, if you want a patch to have a wah, you need a wah block in that patch. You can get the wah to shut off in a number of ways, but the coolest one is to use the "Auto engage" feature of the controller you assign to the wah block's "Frequency" parameter. When you assign the controller, scroll down to auto engage to turn it on.

Sorry for all of the questions, I am not very knowledgeable when it comes to MIDI.
That's what this forum is all about. You may want to learn to use the wiki to search for these things, as they are already well documented. I know it can be intimidating, and does not have the immediacy of a straight answer to a straight question like you can get here, but once you get the hang of the wiki, it becomes easier.
Cheers,
Daniel
