Aeros muting tracks & external footswitch

Hi all,

I am new to the looping/MIDI world, so it might be that my question is quite naive, but there it goes. I have not been able to spend enough time with Aeros yet, not as much as I would like, but I am starting to be able to do what I want to, yet there are a few things I think would help me signiicantly.

One of them is the ability to mute a track in a single click. I know this is one of the things people on Singular Sound want to implement, but I was wondering if using an external footswitch could help on this.

If I am not wrong Midi Maestro should allow this, but currently it is completely out of my budget, so I wanted to ask if anyone uses any other device for such purpose.

And another naive question: I am using Aeros together with BeatBuddy, so the Midi IN port of the Aeros is occupied - if using a midi footswitch, even Maestro, where should I have to connect it??
