I've made several instruments track preset with Cubase 5 / 6 / 6.5 / 7 / that doesn't work now with the new track instrument of Cubase 7.5 whatever VSTi I use (HALion / HALion Sonic / kontakt...).
That's because the first output of the instruments, originally used in previous version of track preset (one output one midi channel) is desactivate (off), I'm oblige to activate the second output & desactivate the second and reactivate the first..... whaou !).
I've try it on 4 different computer.
thanks for correct this because I don't want to resave all my instrument track preset (if you save a instrument track preset in Cubase 7.5 it work !)
