Ratings and Reviews

Decent mono synth in need of some tweaks


I was interested in this synth at release, but waited until the update brought it AudioBus and IAA compatability. These features now work, so you can use it to record music. And for a 3 dollar synth, it does a pretty good job with its twin-oscillator engine and all-on-one-screen interface. Since it is monophonic (one note at a time), it's probably best suited for bass and certain types of leads.

My one primary complaint with the synth right now is that it has basically only 8 preset slots and I kept accidentally deleting my work by bumping one of the preset buttons. Also, I believe it is CoreMIDI compatible, but not VirtualMIDI, so you can use it with hardware like an external keyboard, but not an iOS MIDI sequencer - which is a strange omission. Fix both of these things, and it's a pretty solid basic synth.

Wow, this synth is very cool...a great sound to have on the pallet


Mono synths can get dismissed sometimes by those who didn't grow up in their heyday or those that did and dreaded their "quirks" ruining a show or session.

This app captures the feel and sound of a vintage synth while the great iOS music platform and touch interface brings it into today. This is a great app and for the price only makes it sweeter...

Nice one


Definitely worth the asking price, even better when you run it into a reverb or delay app via audio bus, a note to the developer, If I didn’t have to navigate to the midi menu and enable my irig keys every time I open it would be great, all the other synth and keyboard apps don’t make me have to do that every time I open it, other than app great work.
