I am in no way a computer or electronics person.I just wanted to see if it would be possible to add/upgrade the CPU to the axefx maybe by building a small black box that could be connected to the axefx that would have additional chips for more processing power.Rather than designing a whole new axefx3 maybe being able to add additional CPU boxes,they could probably be small and rackmountable.Kind of like adding additional hard drives to a computer.There are 48 blocks that can be used in a preset,but not enough processing power to use them.I understand most everyone is not going to use 48 blocks in one preset,but it would be nice if there was more processing power to handle the complexities that new upgrades in firmware seem to need.Like I said I am not a computer person,so I don't know if this would be physically possible to do,it just sounds like a good idea if it were .
