It looks like some kind of effect is engaged. Perhaps you can make sure that: 1) The FX Sequencer Mix level is at 0%. 2) That no FX are loaded (i.e. it is set to None) on all 3 effect slots on the Control Window (Left, Output, and Right - the Output FX slot is below the Transition tab) 3) You've disabled the Mixer FX (in the menubar, go to Window, then Mixer FX, then disable all of the pink and yellow buttons) 4) In MixEmergency's Preferences, the option to "Automatically load effects", and "Automatically save effects" is disabled If you record and export another short mix, do you still see the issue?
