Hi guys,
There was a bug a while back where projects would remap the midi inputs to another controller when you reopened the project, this was fixed, but now appears to be back again. The fix last time wasn't 100% fix either, it only fixed new projects, old projects would continue to map to a different midi controller. It's not the end of the world, but it is super annoying. What is worse though, is that sometimes the outputs map to a different soft synth, so if you've got a projects with 10 or so synths and suddenly all the midi tracks are randomly pointing elsewhere, it's a little tiresome to fix
Cheers
