I have the MM19 premium edition and everytime i start using VTSI instruments with ASIO driver the program crashes, when i record voice programme crashes, which is very annoying. I have found that selecting my driver as the primary driver, then the programme works fine, except when i try to play vtsi instruments i can not hear any sounds when i press the keys on my midi keyboard, but if i record the vtsi instrument i can hear it on playback, just not live???, i have to eekp witching back between drivers everytime i want midi, but at the risk of the programme crashing?

I bought the programme to play my midi keyboard but this is so frustrating

Any help would be massively appreciated
