How do I fix it?? Something in reverb settings???yep, High CPU. The drive and the reverb are paused due to lack of available CPU.
On the AX8 normal is the lowest settingPossibly you could lower the density in the reverb and the quality to low. for the drive you may have to select a lower cpu drive type, or maybe there are some external controllers that are attached using up cpu. If you do not use all those effects at the same time maybe divide it up into a couple of presets.
