Switching presets on the Eclipse won't be a problem for much longer as I've ordered a Boss FS-6. Its the control of certain parameters (e.g. size) that dictate I need a MIDI controller, which the Space pedal does, only it unavoidably changes the paramters of its own presets in doing so. Of course, if Eventide were to come up with a smaller version of that $2k MFC, life should be simpler and easier.
