I'm too having problems with Novation Twitch ASIO and CrossDJ. I have installed the latest Windows 10 updates. In Ableton Live the Twitch ASIO works just like before. Now I need to try another soundcard/controller.
EDIT
did some testing
Twitch ASIO , latest WIN 10 updates
CrossDJ 32&64 bit : not working
Ableton Live : working
Serati DJ : working
Reloop Mixtour ASIO still working in CrossDJ.
Tried deleting .settings, reinstalling Novation sound card drivers,
reinstalling CrossDJ. No help there.
I managed to get it working on Saturday for a gig after several reboots and closing and opening of CrossDJ. Not sure what did the trick there.
EDIT 2
Funny thing though, on my workstation laptop (also WIN64 and latest updates) Novation Twitch ASIO works with CrossDJ too!
EDIT 3
I got it working twice now, tried setting the laptop internal soundcard as default for Windows sounds, tried switching on quiet hours setting and rebooting, then it wouldn't work right away with ASIO but switching back and forth with internal and controller ASIO and disabling inputs did the trick. This is very strange !
