Tap Tempo for playing live

I just recently purchased my MiniFreak and love the thing! I’m looking to use it live with a band that does not use a click, so I’d like to be able to adjust the tempo on the MiniFreak on the fly.

One suggested solution was to use a pedal like the micro.clock by Disaster Area. Has anyone tried this? Can anyone suggest any other ways to accomplish what I’m trying to do?

It would be great if there was a “tap tempo” button on the MiniFreak, but there doesn’t appear to be a way to do this. Preferably I would like to use the MiniFreak on its own without involving a computer and keep things as barebones as possible…

Thanks in advance!
