I still use this synth in my music production to this day many years later. One of the most high quality unique synths on the ios platform with beautiful sounds.

Well isn’t this amazing!

I found this by accident as I was searching for something that was Buchla. This is amazing and free. I can’t believe the sounds it creates which are other worldly and the whole plug-in itself lends to involvement and to happy experiences. Kudos to the developer.

MIDI can't select a channel

Sounds good but no matter what you set it on, it always responds to every MIDI channel, making it kinda useless as part of an ensemble.

Fluid and unique

Exceptional way to experiment with sound. Nothing else like it

The best FM synthesizer ever created

The title says it all. This thing does everything I ever wished my DX7 could do, and with a user interface that makes it as easy as editing an FM synthesizer with this level of functionality could possibly be. I really don’t have anything negative to say here. Been using this app for a few years now and I still feel as though I have barely scratched the surface of what is possible. Thank you for creating this, whoever you are.
