Near total MIDI newb question RE: hardware connections

Hi Ruefus.  Welcome to your MIDI journey.  Of course the easiest way to use MIDI Designer would be to connect directly.  With your current setup the way I would think of connecting everything would be to connect the iPad to the MacBook via Bluetooth and send MIDI out to the Presonus Audiobox via USB.  This is a fairly complicated setup and I don’t know if the Audiobox would convert and send MIDI sent from USB to MIDI Out.  I doubt it would but check the manual for certainty. Do your guitar pedals have direct 5-pin MIDI ports or TRS/MIDI ports?  Which guitar pedals are you trying to control?  This would make a difference in what I recommend.
Thanks for your reply. I've finally had some time to try a few things and I've had some success using your advice. As convoluted as this setup is, it hasn't cost me a dime. All of the cables and hardware I already had on hand. Including a Radio Shack branded MIDI cable I've had forever.

The pedal I'm wanting to control is an Atomic Amplifire 3. It's an amp modeling/effects unit with 5-pin MIDI ports. The connection goes from the Mac via USB to the AudioBox. AudiBox to Amplifire via 5-pin MIDI.

I used Presonus' own Studio One recording software and it's MIDI control capabilities to try it out. I mapped a CC# in Studio One's control setup and am able to control the AmpliFire. Which is very cool.
Great, glad to hear it is working for you and you saved some cash!  Did I answer all your questions?
