Customer Reviews

An add blocks like a fourth of the view of the app

Not exactly but it's blocking enough of what is essential to synthesis. I recommend the moog model 15 for 30 dollars if you want to get into some synthesis that you can actually see. I get that it's a free app and all but come on with the add blocking that much of the screen is that really necessary? There are plenty of free apps that don't over spam with ads.
And I am not rating this one star. Negative one would be more accurate.

5 Stars--but...

...needs audiobus support and really a lot of other touches. Could sell for $5 or more with improvements. So it depends on how motivated the creators are...alas.

Like my old Yamaha CS 30

This thing really reminds me of the old CS series synths by Yamaha before they did the dx7. Very cool to ,really great ,..if you get the pro version . Peace christo
