Yes, I was going to ask if your chord looper hack could be used, and apparently so.
But it just seems like such a weird thing to remove!
After all, on the chord step recorder you can specify which channels are active as well; can you on the chord looper? (not the biggest deal in the world, after all you can delete the specific midi notes after rendering, but it's just so much easier to not render them in the 1st place if possible)
