Midi controller for the Strymon Timeline Looper

Hello all, I am a new member and am currently working on my first project with Arduino. I hope to be constructer a MIDI foot controller with four switches. The idea is that 3 of the switches will control two separate values. The fourth switch will change the values in which the original 3 are controlling (almost like a bank A/B switch). I will post pictures of the materials I have and the blueprint I have drawn up. I don't know the capabilities of the Arduino UNO R 3, but hope I can find some help on the direction I should be taking.

Thanks for the support
