With the ASM Hydrasynth Explorer, you can make music anywhere. The synthesizer runs on batteries, so you don't need a power outlet. You can use it wherever you like to express your creativity directly through music. Thanks to the polyphonic aftertouch, the keys of the keyboard are pressure-sensitive. You decide how each note influences the music and conveys emotions. When you lightly press a key, you hear a subtler tone than when you strike a key forcefully. The arpeggiator ensures that you can transform a melody into a rhythmic and melodic pattern, repeating the loose notes of the melody in a pattern of your choice.
