Etheric Synthesizer (EtherSynth) is a theremin-like synthesizer which allows you to play otherworldly melody by swiping finger on device's screen. However, it is not aimed at realistically imitating a real theremin as it only uses single finger to play. Features: * Play tones with single finger. * Colored gradient background guide (can be turned off). * Visible touch indicator (can be turned off). * Configurable frequency range. * Configurable control axes orientation and locking. * Configurable output waveform: sine, triangle, sawtooth, and square. * Configurable output audio resolution. * Performance could be recorded in WAVE format.
