Trying the demo. I find pretty strange to be forced to use a tiny window in order to edit modulations/sequencing like I was using a real piece of (limited) hardware while it's software so it would be easy to open a big comfortable window large as the entire screen (eg. the wavetables editor)... and yeah, fake wood, fake vents, all wasted space... also +1 for layer activity lights (just make the layer buttons flash when the layer emits sound)
I think the central space would be much more useful if used to display OSC2, for example.
Also no search in the presets browser, no online user share library (I use synthmaster and love that feature), no favorites...
I would move out of the menu the undo/redo, placing them as buttons somewhere in the screen...
But the sound is indeed very good...
