I've downloaded your patch, and I will take a look when I have a moment.i have an envelope wah in this preset which should be bypassed, but SOMETIMES when i load this preset the wah is on. There is no autoengage enabled, and preset is saved with wah off.
There are no global blocks.Are you using global blocks for your wah? Not sure if the AX8 has global blocks or not, if it does then maybe you are changing/saving a different state in a linked preset?
