First, I shifted the channels up in the no Yoshi drums version to alleviate SFX cutoff. #6 and #7 are now #5 and #6 respectively.
Second, you don't need to keep redefining @10 for every note (unlike with instruments @[email protected]) since it is not considered a percussion instrument by AMK. Hence, redefining it for each repeated @10 note takes extra space.
Third, I changed #optimized to #default since it inserts fine.
Finally, some loops, such as this one, can be optimized better by being condensed.
