Over the weekend I bought a new instrument and while downloading also upgraded to Kontakt7. I use a Komplete 88 MK2 although I don’t think that’s the issue. I use Logic as my DAW. Ever since, in any of my old projects, if a midi track is selected that track doesn’t play right. It gives you little blips of the intended sound. Same if I play through the Komplete. I've duplicated tracks, created new ones. No matter what this happens in any MIDI track. However, if I create a whole new project everything works fine. I simply can't work on any projects created before I upgraded. I can’t figure it out at all and I’m going crazy.
