Great blog Dan.
I've been dipping my toes into channel splitting using the bass murf's stereo outs & putting it on static.
The good thing about this is that it sends different frequencies to each channel, so less chance of phase issues.
I need some more fx (such as an octaver) to actually make good use of what I have, but it's fun.
Come to think of it, the mixer that I'm using to blend the sound back together has an fx section. I'll try assigning something to a channel.
Most recent try saw my signal path go:
Murf right channel > boss CE-2 > cheapo distortion > LPF > mixer
Murf left channel > mixer
The murf was set so nearly nothing below 160 hz was going to the right & nothing above it goes to left.
It's not just keys that step on your toes, guitarists can be equally as guilty (in my instance, one has an octaver on octave down! & the other uses a Godin with a synth set up so 1/2 the time I could play up the dusty end).
