New look

We wanted to make this skin simple and friendly. We rounded off the sharp edges, chose colors that would look great in any DAW, kept the emphasis on the oscillators by making this block lighter than the others. So, take a fresh look at your favorite synth!

Simple design

We don’t like design for design’s sake, in other words to complicate what can be done simply. So you will not find here beautiful, but useless design elements that only distract. We like simplicity and functionality.

Clear and clean

The FLATROCK Serum skin was created using vector graphics, which means it is fully scalable and looks great on 4k and Retina screens.

And more

• Compatible with Retina and 4k displays • Minimalistic design with analogue soul • Free updates with improvements • Easy to install
