confirmed on drum editor, midi editor, toggle note shape, quantize, humanize & filter buttons, seeing as note shape is a toggle it makes sense i guess but drum track & midi editor view buttons should hold a pressed state IMO hide unused button dose hold clicked state! is there a toggle option i can do for this? or do i need another button for show unused? will test some more with the hides carrying over to different midi tracks then post back :) Subz
