Bruno: to my opinion this has nothing to do with midi settings.

Bert, my logic is being challenged here. I used the subs to send the sound as you did and for 1 ½ there was no change in my setup, as soon as I played the midi file the settings changed. I tried the same at home and got the same results. This only happened with certain midi files. Was something else going on, I don’t know.

After that I used a BBE and an EQ to come a little closer to what I wanted.

Good luck, John C.
