#134 goes down a minor third; up a major third.
Maybe it's because FX Consoles were used for sound effects that might required more variation in speed to be useful, but I do know that 10030 goes down at least an augmented 4th, because I've done that. Or maybe it was a demented 4th... I was on drugs at the time.
Martinge, can you provide guidance?
No, wait. You're on drugs all the time.
