midi for percussion

[Alan Szlosek]

I'm interested in helping to get flams, accents and diddles (drummode) to come through in MIDI output. Can anyone point me in the right direction? Or is anyone currently working on this?

Only the first flam seems to come through. I've tried on version 2.13.4 and 2.12.1. When generating output I get these errors:

programming error: Going back in MIDI time.                                    
continuing, cross fingers 

I assume it's the flams. I'm using the following code to generate flams:

flam = \drummode {
    \override Stem #'length = #4
    \acciaccatura sn8
    \revert Stem #'length
    \stemUp
}

Thanks in advance for assistance.
