I understand this may be advanced and confusing to people, but I'll try and answer questions as best I can, and I hope this helps some folks out. It has been well tested and has shown no major problems, but is not finished.
You need to set up an IAC driver and then send your midi signal into Midipipe and then have it coming out of your IAC driver and set that driver to "track" and "remote" in Ableton.

IE: you can use one button to control a series of other buttons that normally would always be sending the same midi note (those foot pedals). The Applescript is pretty cool, because what it does is look at what button you are pushing, and then modifying the midi note that is being received by ableton depending on that note. I'm hoping that with a little patience, people will be able to modify this file to meet their specific needs and extend it, etc. I am planning on setting up effect filters in each looper (like in the above tutorial) and then control those with the left foot pedal. I also have the footpedal on the left set so it will be selectable as well in exactly the same way, but I haven't yet assigned it to anything in ableton.
IE, if you have all five loopers playing, and you want to reduce the volume of looper #3, you would go to bank 1 and press pedal #8 to select the correct looper and turn down the far right footpedal. On Bank 1, buttons 6-10 simply select which looper you are wanting to control and then the far right footpedal controls the volume of that specific looper. On bank 0, buttons 6-10 control the "clear" button of each looper. So pedals 1-5 control the big button of five different loopers. I have the footpedal mode so the bottom five pedals are the stompboxes. Sorry it is so customized, but I have my foot controller programmed for a very specific Ableton live set, and so I wanted to also create a live set and use the same settings for this looper so I don't need to change things around live. This will require you to either set up your FCB to send my specific notes, or for you to change the Applescript in the midipipe file to meet you needs, but if you know basic coding, changing the script wouldn't be very hard. I decided to make a Midipipe file that would meet my needs.
