ToneBars is a proximity tone generator for audio production and performance. The volume of the synthesised waveforms are determined by their position on the play area. the closer to the top of the screen the bar is the louder the relative sound becomes.
The volume, pitch and rate of the bar's waveforms can be edited via the ToneBars editor.
