I wonder what could be wrong with my audio files because I have the following issue: I drop an audio file in Kontakt to create a new instrument, then activate the range tool and change the source from DFD to Tone Machine, everything fine so far. I can adjust every knob except the Formant! As soon as I start to turn this knob and play on the keyboard, the sound is gone and Cubase freezes. I´m only able to kill the process in the task manager. This is not happening with all of my audio files, and this is very strange. They all have the following formats: .wav 44kHz-16bit and 48kHz-24bit I´m on a windows 10 / 64bit machine running Cubase 9 and the latest Kontakt version. Any ideas what could cause this? Is there a length limitation for processing files in the tone machine mode?
