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.

Customer 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.

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 I own them ALL so my standards are realistic when I say this one is outdated junk...

nice interface, good sounds

I grabbed this app a few days ago on sale, and after having some drama with installs and crashing, I finally got it to work by deleting it from my iPhone, downloading it to my iTunes on my desktop, and reinstalling it from my desktop to the iPhone.

the sounds of this app are fun and very usable, however somehow it doesn't have the essence of the juno line. the chorus is especially missing the gooey space that my old Juno had. all said and done, the controls are fun and easy to use, and the sounds are definitely inspiring so long as you don't expect them to save you the money on replacing a real vintage Juno.

also, the lack of exporting options are kind of a drag. please at least add audio copy so we can get these sounds out into other apps for editing and sequencing.
