I have a few rack fx units I will have on rack mixer's sends/returns: Lexicon MPX110, and TC Electronic 3xx. I recently decided to get an Eventide Space because like the rack units, they all can also be used creatively with their midi implementations, and dual mono or stereo inputs/outs...it sounds DREAMY with the Sub 37, and I think the 'analog warmth' is left untouched, and this goes for when I run the Waldorf pulse, or when isolating only all the analog oscillators on the Poly Evolver. I do mostly Ambient, Dark Ambient, Space, and Experimental/Industrial to even noise. I really love all the user interface of the Eventide Space with logically placed knobs and even assignable knobs, and display, so it's like so much akin to doing sound design on any synth, I have relegated the Space for my Sub 37 rather than rack units. Not that they are bad, it's just nice to have different 'flavors as options', as to stand apart from the pack, so to speak.
I still want to get a MF104Z or the Minifooger Delay as having other options.
It would be wonderful to set-up a Sub 37 and some powered monitors within a cave that is commercial tourist location where there's indeed electrical outlets/lights, to play the Sub 37 in a TRUE cavernous reverb...that's on my imaginary bucket list.
The Eventide Space is truly amazing and bet it could match the aforementioned cave adventure spot-on.
Now to embark on doing this newest update today.
