This synth is off to a great start. Despite how simple it looks, it can create an extremely large variety of sounds and tones. It's has its own kinda take on FM, but is as easy to use as a standard subtractive synth. The developer is highly responsive to communication. I gave it five stars because I think with a few more features it can grow into a great synth for a pay-what-you-want offering and because the developer is so responsive.
