What I like about the FI is that I have other people to struggle with that stuff for me who then just present patches which enable me to say "that is ace, I can use that" instead of "this pedal looked ace but I have owned it for 2 years and can still not make head nor tail of it". This is not being lazy. Too many parameters make my head all fuzzy. I can not even read piano music because there is too much going on.
I am presuming that can only be 2 switches on a stereo lead? More would need midi magic which would put the total spend up to as much as bigger brother. Am I right?
Are these all much of a muchness before they see a preamp or are some better than others? Given my extraordinarily limited understanding of the tech, a strip of piezo electric crystals is a strip of piezo electric crystals, no?
I have messed with mine on upright. It is my intention to program it to have a filter with will open progressively the more arco pressure I apply. One day. Maybe.
