Alesis Andromeda A6

it does work, 
have you set off the midifilter for transmitting and receiving system
exlusive data ?
find it somewhere under fifth colum  /system/midi or so. be sure to
put off the labels before system exlusive through when playing it back
to the a6 and , for the system exclusive record when sending it to the
computer. when both are set to off ( = no label before it ) you might
get a midi loop problem. hope it's clear this way and didn't mess it
all the other way around, you see i'm doing it out of the head right
now, so good luck it should work.
