I open it up how good it is and would say that it is one or maybe the most advanced synthesizers you can get for Android. It does not hurt that it sounds very good to!
Was playing with it some days ago and now with full midi control there will be a lot of playing with it over the weekend.
There is a list of Midi Controller Mappings on their website and it seems that it covers all
or almost all the functions of the Synth.
Definitively worth getting if there is any interest in synthesizers.
● Added support to modify parameters by midi controllers.
A full CC list can be found on the web page
● Added "Reset" menu entry to reset all parameters to a default state
● Various UI improvements
● Various bug fixes related to VST integration
