I tend to agree with you Diki, most of my arrangers lately have had the capacity to do things with left hand pressure, but it's just one more thing to think about.
I have gotten really spoiled to dedicated foot controllers, on Audya, Korg and Roland. I'm going to have to find one to use with the 950, should I decide to go with it.
I only require 3 or 4 extra switches, to control Vocal Harmony off/on, text page up down, a break/fill or two... I still prefer a larger sustain pedal and occasionally volume pedal.
I'm researching this now.
I'm also researching a VERY small passive mixer, just to have the ability to use an extra mic on occasion, and not use an external mixer. I have a couple I can use, but always on the lookout for something better and smaller.
