Yes everything sounded distorted when i checked for what had changed.
Also the labelling on the midi delay still seems wrong. When active the delay values show in in milliseconds and when inactive show in tempo. Thanks for the quick post, you pipped me too it. I couldn't quantify what i was hearing but thought i had changed the settings on a preset by mistake and turned the gain up full into clipping.
Thanks to Arturia for the come back.
