Don’t know what other subforum this should be in but this seems weird. Of course on top we have tabs, and the currently active tab has the icon colored/highlighted. Inside sampler though there are these ‘sections’ if you will, but “Waveform” is always highlighted, no matter which one is active.
side note
(I think) it would be awesome to have the sections resizable, see the modulation ‘playhead’ move at the same time as you see the sampler playhead.
