Cubase 15.0.1 Was having trouble on boot ‘Initializing: All MIDI inputs’. Had to restart my computer. That solved that, but now Cubase is hanging up on a project load I’ve been loading repeatedly for the past 2 weeks without problem. edit It’s now stuck on Initializing: All MIDI Inputs again a…

Hi, Please, read this article. [image] Cubase refusing to start, stuck on "initializing midi" Cubase We have fixes for all the common problems on the Discord server. I’ll help you there if you end up stuck. Windows MIDI / Audio (please read the #start-here p…

for what it’s worth, whether it was just by chance, I uninstalled these updates: [image] did two reboots for both uninstalls, things seem to be working again…

I know it’s what folks are used to doing, but I wish you would not uninstall the updates, or at least wouldn’t recommend that others do it. I keep running across customers with broken MIDI systems because they uninstalled updates which were just the fixes to the January release. It results in a par…

Being in the middle of a gig, I needed the fastest resolution. But oddly, everything has been working fine for me up till this morning when it did those latest updates… So did the fixes break something for me? I don’t have Discord… edit The uninstalled updates have reappeared in Windows update a…

For the KORG, I recommend uninstalling their driver if you are using it. It’s not needed, and does cause problems under the new stack. (What you listed are MIDI devices, but some may be using our in-box class drivers, and some may be using third-party drivers). [image] News | Request to di…

So uninstalling the Korg driver should solve my issues? not using RTP yet

Anyone having weird problems after latest windows 11 update?
