It became clearer what's going on on the screen: all arpeggios are now visualized.I got rid of the misleading (and merely ugly) waveshape morphing. All the waves on the screen are now smooth and steady.A couple of minor UI improvements (or deteriorations, you decide) implemented:- Tonic is marked by thick line instead of a colour.- Line colour indicates the currently pressed key rather than tonic.- arpeggio visualizations are drawn on a different layer in grey and don't distract from actual controls.
