There’s a thread (Shortcuts with ALT key acting weird) on this problem already, but it’s over a year old so I guess it’s better to open it again?
Any keyboard shortcut using the ALT modifier does not work at all. Not in context nor can they entered as keyboard shortcuts in the options window. Basically Renoise seems to either eat up the events and not process them or somehow misinterpret them. This only occurs in Renoise 3.3(.1) though. The shortcuts work fine in 2.8.2 which I’ve been using to this day so far (looking to upgrade now finally), and it did work earlier in the 3.1.x versions. As noted in the old thread the problems apparently seem to have started with 3.2 which I didn’t test drive much so I hadn’t noticed it.
My situation funnily enough is the same exact one as user ASC in the old thread. I’m using an Apple A1243 keyboard on Windows 10 with SharpKeys that swaps the Winkey and Alt keys. The issue seems Renoise specific since over several years that I’ve had this setup (both at home and work) this is the first time I’ve had an issue like this. I’m not looking to switch out my keyboard though, since this is my favorite keyboard I’ve ever used. The issue is essentially a showstopper for me and would probably force me to stay with 2.8.
