Exakt Lite

Exakt Lite is an intuitive and user friendly FM synthesizer plugin. From the harsh digital and cold sounds known from the FM era to warm and organic sounds, Exakt Lite can create a wide range of sounds.

Exakt Lite has got 4 operators which can be arranged in the classic 8 FM algorithms with feedback on operator D. Each operator has got different waveforms such as the basic sine, saw, square and triangle. Additionally, the 8 classic waveforms from the Yamaha TX81Z are emulated.

Each operator has got a separate amplitude envelope generator supporting the classic 5 point TX envelopes. These envelopes have been modeled to mimic the TX characteristics.

The plugin UI has been created using vector graphics and supports blur free resizing.
