Hi Brian,
I had similar concerns as you have about the foot switches.
First off I decided to have it on a stand close to me since I already use 2 foot switches and I wanted to be able to see it better.
The switches are very easy to push with your finger. Second you can very easily do a step program with all the changes you want (like building up a song). Once done all you need to hit is the step switch.
So for me I either hit the Harmony switch to turn Harmonies on and off, or the step switch for more advanced changes.
I hope this helps.
Eric
