It is H9’s hardware limit. Some algorithm is computationally heavy. When you move your expression pedal, a number of parameters are changing. So there will be a lot of computation going on in the processor. For those algorithms, if you unmap all expression mappings and only use the expression for the input volume, it may behave better.
The expression pedal mapping being bypassed when the the patch is made globally is accurate. I also deleted all expression pedal mappings on a few various effect algorithm presets with no apparent improvement in the zipper noise.
So is the issue of zipper noise when using an expression pedal to control overall volume one that can’t be improved because there are simply not enough computational cycles left afetr the wonderful Eventide effects are crunched?
I simply want to know if i am barking up a dead horses’s tree:-)
If so I will find another way.
Thanks,
