>Ahsun Sound Machines (ASM) have revealed a new, portable version of their excellent Hydrasynth. Known as the Hydrasynth Explorer, this offers the same 8-voice sound engine as its big sibling, but in a more compact and battery-powered package. Also new from ASM is the Hydrasynth Deluxe, which goes the opposite direction by upping voice count to 16 and including a 73-note keyboard.
