Thank you, Bernie, Mike and Bachus. It is an extremely tough tune with lots of complex jazz chords.

As most of you, I think the cost of losing editability is much too high compared to the tiny difference in realism of the drums.
If you have a purely consumptive attitude with respect to the sound content and only want to use what the manufacturer has prepared and edit nothing, then audio drums might be a good way to go, but I think many players do want to be able to change things.
Audio drums are another step of turning an arranger more into a mere instrumental playback machine for singers.
