He was highly impressed when I demoed it (I say 'was' because he sadly passed away last September after a brief illness). This led me to your App, which I instantly downloaded for my iPhone, although I had actively been discussing creating exactly such an app with a fellow programmer.
I found your app while listening to the work of guitarist Lionel Loueke online, and something told me to Google your name further (as a guitarist I've always lived with and amongst bassists anyway). Greetings and congratulations on such a fine job in iRealB.
