Bakerman, I believe that I stopped using the autoengage function for awhile, because I didnt like the 5% as my pedal moved for that 5%. I felt I could get more travel out of adding a modifier to the Bypass parameter and trial and erroring when exactly the ball travels above/below the 50% line which would turn the block on/off...this gave me a slightly more usable sweep range for effects like the way...and also more 'instant' changing when activating other blocks.
Decerto,
If you want to invert what I'm doing by not using the auto engage, you would set it up like this.
Bypass Mod settings
Ext 1
Start - 0
Mid - 0
End - 58.3
Slope 0.0
Damping 12ms
Auto Engage - Fast (as Bakerman suggested and I 'forgot', this is really only used if you arent going to set the ball travel as I am, I believe.
By setting the bypass on the wah block like this, this would then set the heel down position as 'off', when you rocked the pedal forward, it would cross the 50% mark on the graph and activate the blocks wah/eq. The modifier for the FREQ parameter would not have to be changed because you are still using the expression pedal in the normal sweep direction where toe down is the treble side. If you wanted to invert the sweep where heel down is the treble side of the sweep, then you would invert the min/max settings on the FREQ/WAH block.
Make sense?
