I love this synth. It's called the beast and rightfully so. It's extremely flexible and has alot of controls that are fun to mess with. Developer was helpful, you can layer multiple synth tracks by assigning them to the same midi channel. Hoping for a keyboard split feature in the future. Nice work.

It takes a little work to learn the interface, it's kind of weird, but it's worth the effort...The synthesizer itself is is fairly versatile and it's one of the best ones for an Android..Which do not compare to the PC ones which are better.

The app is one of the mainstay apps I have on my phone a long side the Studio and the drum app by the same ppl all of which I have, it has been a hidden gem. The other DAW and syth apps are also boosted by the use of this app. GOOD WORK MY MAN. Btw I have RARELY rated any app 5 *'s so that is a good indcation of how good I think this is. And the addon IAP packs are top notch too.
