Hi there, I have a pad that triggers a song wich has only a brightness 
control mididata recorded on it, on Channel 10.

I had this working so I could hit the pad and all the drumsounds were 
filtered. But I losted the settings and Im trying again to make it work.

But now I have the strange situation that the padsong plays the song 
but the effect isnt heard, but when i push the playbutton, and the song 
plays that way, the effect will heard on the drums I play.

I dont know what this implies, does it make sense to someone, maybe Ive 
messedup some midisettings.

Thanks in advanced,
