Epic Synth is a polyphonic substractive synthesizer inspired by classic analog synths of the 1980s. Its beautiful and familiar interface helps you focus on what matters the most: creative musical exploration!

Epic Synth’s straightforward and effective sound architecture stood the test of time. It’s simple enough for beginners to learn about synthesis yet powerful enough to satisfy experienced sound modellers. Epic Synth’s sound engine provides tons of room to create great sounds, from classic leads to juicy acid basses, from 8-bit-like effects to complex evolving sonic textures.

Ratings and Reviews

Wow! An update?


I'm being honest when I say I wrote this one off as abandon ware and never thought there would be another update, I'm mean It's been close to 3 years!!!! Having said that I'm glad to know when iOS 11 comes out this will still be relevant. What would really be a great update would be audio unit support, would love to see that implemented some day.

Great-simple, easy to use- don't have to mess around with tons of knobs to get something good.

Sooo buggy

Literally tapping the upper right part of the base menu screen starts changing variables on the edit screen. Such a waste of 5 bucks. I own them ALL so my standards are realistic when I say this one is outdated junk...
