[Freepats] Steinway_IMIS2.2 soundfont (no loops fix)

[Roberto Gordo Saez]

This is Steinway_IMIS soundfont, version 2.2.

ftp://musix.ourproject.org/pub/musix/sf2/Steinway_IMIS2.2

This version fixes the issue with loops. I hope this is the good one
and there are no more remaining major bugs.

Marcos is a little busy right now, so he asked me to make this fix. He
is thinking to make other improvements, so expect more updates soon.
