I replaced my Eventide Space with this as I wanted the presets to change instantly, without a second of waiting for the next preset to be loaded. This one does it. However, if you switch into a preset with a high wet level, there is sometimes a faux spillover. I assume the spillover from the previous preset gets fed into the new preset and creates something that sounds a little like a tape delay for a second. It doesn't happen all the time, and I don't think it will be a problem in any live scenario. There are no level spikes when switching presets, unless you programed them with different levels. Every function can be remotely controlled using MIDI. Everything!!!! The manual does a great job of telling you how to. You can even save / load presets using MIDI commands. It is a little picky with SD cards, but once you go to a shop and get the right one, it's smooth sailing.
I have been blown away by it and I keep finding out more reasons to love it almost daily. It is pricey and there is no display and it only has 35 presets, but with a DAW, and some clever MIDI CCing, this becomes a limtless preset pedal.
