Ha! You've discovered some of the other voodoo that an outboard DC-coupled interface allows!

This sort of thing is why I went with it. Instead of having the CV I/O as a device-dedicated setup, using an external interface in this way is much more fluid. And given that Ableton WILL allow multiple types of streams to the 828 via CV Tools along with the easy (and CHEAP) implementation of more I/O channels...well, hey, it kinda sells itself! And with the right adjustments to CV Tools allowing compatibility to...well, pretty much anything that'll take CVs...it's possible to have those scalings present whenever you call them up.
