If you plug a keyboard into a stompbox, do you have to convert the 
impedance? Too hot, distortion, all that kind of stuff? Most direct 
boxes change high impedance to low impedance. Wouldn't a keyboard going 
to a stomp box want the opposite?

I've been mute on this one because I've never plugged a keyboard into a stomp
box -- ever.

As far as the tech/geek stuff goes, I know that the output impedance of a
keyboard will be "line level" which is about 600 ohms IIRC.  Guitars tend to be
in about the 5-20k ohm range so that would tend to push a bit more voltage into
the front end of a pedal than it would be designed for.  So it might sound
crappy or cool depending on if the pedal could handle it.

Meanwhile, back at the rack, maybe you might look into a mixer with an Aux loop
instead of all the expense of DI boxes.  I'm using this old Korg thing that's
got some Aux send/returns that have effects units on them... but of course
that's all in the "line level" domain -- no stomp boxes used.

From your past posts it seems you've been pleased with some stomp boxes.  Maybe
you're onto something by the "happy accident" mode.  Or maybe the distortion is
effecting your cannabis receptors orr thhe otther wway aaroundd.
