[Freepats] Testing piano soundfonts

[Roberto Gordo Saez]

This is a test for the IMIS acoustic piano soundfont, compared with
a proprietary soundfount and with a real piano recording.

Music is Beethoven's piano sonata No 23, Op 57 "Appassionata", 3rd
movement, a more demanding piece of music than the previous Für Elise
test.

1. IMIS acoustic piano soundfont. Please listen the complete piece
of music; your ears will get used to the sound and will be easier to
notice the differences latter.

2. The same file, rendered with a proprietary soundfont. This soundfont
is similar to our free soundfont in size, and it is also made from mf
(medium-loud) samples only, but it is supposedly finished and well
balanced.

Comments are appreciated. First impression to me is that most important
differences in quality are beetween G2-B3 notes aproximately. I don't know
why.

3. And finally a real live piano performance by an experienced pianist.
If you have carefully listened at the other two, the first thing you will
surely notice is a hall reverb, and then you will probably notice that
the sound is far more pleasant, natural and smooth that the other two.

The music is from Hyperion Records' listening room:

Pay attention to the expression that the pianist gives to the music. Soft
and very loud notes are used to communicate feelings, and the difference
with computer renders is quite noticeable. I hope the soundfont will be
closer when more layers are used.
