Using version 1.1 realised that:
- when fading alpha blending (slider on layer) performance fps slow down a lot, making fading in a layer not an option...
- when changing values by knob or faders (with mouse or midi) (for ex. color modulate) at the time a layer is selected slows down framerate. But just when changing a layer which is selected, changes in other layers (possible using a contextual midi setup) don´t decrease fps.
