Hello Burkhard,
After trying to make the settings directly through my Kemper Unit, it seems to work well for both a use as Pedal Pitch or as Pedal Morph of my EP1-KP .
Initially, i used Rig Manager to make the settings for my Kemper.
It seems that it caused problems, because i tried to morph the Toe pitch as the other morph parameters.
Thank you.
The Pedal Pitch effect sounds finally grandly, awesome... and this acquisition takes me beyond my expectations !
