Here is, as promised, a little blues noise, using the Twin Harmonica chord and chromatic I put together with the help of Brendan Power. I am using LoopyHD, controlled by AudioBus, on an iPad and a 4S iPhone. The Twin uses Suzuki instruments, all I did was pair them, using the mouthpiece Brendan sold me--oh, and the chrom is bebop tuned--the I and IV are chords on the chrom, only the V is on the chord (in the head--I do some weird stuff at the end, to get out--always hard to resolve a looped performance).
