This has to be the best free synth I have ever used. It has a decent sound quality much alike the "draft" mode on Synthmaster. The sounds come out rich and powerful. The modulation panel can link the LFOs to most parameters in the synth its self. It has a ready to use gate machine built in as well it has sidechain, delay (echo), reverb, and a bitcrusher. All of which sound very nice. The subtractive oscillators work really well. They are easy to use and push out just what you would want. I don't know much about FM (Frequency Modulation) synthisis but it's another feature that this synth features. The portamento allows an easy slide between notes.

Pros: Easy to use interface. Simple to understand. Pointing modulation parameters. It's free

Cons: Could use more waveforms. Audio quality could be enhanced. That's all my complaints
