I posted a tutorial on subway busking with HAPI drums. My HAPI drum stage setup now consists of an array of a total of 6 HAPI drums, a D Minor, a C Akebono, a UFO in C Major, an E Integral (pygmy & akebono) and a D Integral, which delivers all the HANG tones you could want, plus a stunning F# Minor thin guy — it really knocks ’em out in concert!!!
