Harmonaut is a simple VST instrument. It implements additive synthesis. There are four waveform types and 32 harmonics available to create the synthesized waveform. The waveform drawing can be simply done through the mouse. The attack, decay, sustain and release for each harmonic also can be adjusted the same way. Timbre adjustments are done through LP/HP filter, LFO and chorus. There are 32 drawable harmonics available. Separate ADSR is available for each harmonic. The basic waveforms are of four types, sine, saw, triangle and square. Multimode LFO synced with BPM is available. Internal chorus could be added to the synthesized sound. 64 factory presets are available. There is a preset manager that will help create newer presets and add them to the library. The manager can help you edit the patch names. Controls are easily implemented through pop-up menus.
