Great App!
Im not sure why the others had issues with this, all the required software is on the developers site.
I downloaded this app because I needed a custom midi mapping tool for our praise and worship band. After downloading, I went to the developers site for the manual and found the other two pieces of software needed on my Mac to make it work (TouchOSC Bridge and TouchOSC Editor). I spent a grand total of three hours on it and now have a totally customized controller designed for what I needed. I can see that I will be creating many more templates!
