Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!
Released in 2017, the DM48 has been upgraded many times with firmware updates - making the current version considerably enhanced over the original. In this video I give a comprehensive run-down of all its main features, with reference to how they compare with the newly released HM12 Midi harmonica.
