Soundfonts
are files that you can use in order to play MIDI music in a better
quality at the computer. These can be either MIDI files on the hard
disc (files with the ending .MID or .RMI) or the MIDI music in a
computer game like Descent and Monkey Island. Usually, soundfonts
can be recognized by the ending .SF2. In order to use them, either a
compatible sound card (e.g. the Creative Audigy 2 or 4) or a
suitable software (e.g. FluidSynth) is necessary.
Soundfonts
represent a kind of link between recorded and synthesized music.
They contain wave samples and further settings (e.g. pitch,
dynamics, filter settings), in order to control the MIDI synthesizer
of a sound card. The higher the quality of the utilized samples, and
the more precise the settings of the soundfonts are, the better is
its overall quality. Soundfonts not only use the often limited RAM
of a sound card, but also the normal memory of the computer. For
this reason, wave samples can be stored in them in a size and
quality which is hardly possible on sound cards.
By using
soundfonts, one can increase the playback quality of MIDI files on a
Creative sound card considerably. To reach that, they have to be
loaded first. At the Creative Audigy 2, for example, the
“SoundFont-Bank-Manager” has to be used. Usually, it can be
found in the Creative folder. Left to the soundfont (e.g. 4MB
GMGSMT) is the word “Bank”. If you click on it, a new window opens.
In it, you can load or remove a soundfont.
Since I was not
satisfied with the MIDI sound quality of my Audigy 2, I have
developed a soundfont: the 8MBGM
ENHANCED. It is based on
Merlin
8mbgm_plus13 and was
improved with instruments of other soundfonts. My objective was to
obtain a MIDI sound which is comparable with that of my old Terratec
Maestro 32/96 sound card. On the ROM of this ISA card, which has
just a size of 4 MB, 393 instruments are stored. Finally, the intro
sequence of level
13 of Descent 1
does not sound distorted, but in its original quality. My soundfont,
however, is not only suitable for Descent 1 and 2, but for all other
games that support the General MIDI standard. These are many old DOS
games in particular.
The soundfont
technology was developed by the company E-MU/ENSONIQ for the
wavetable synthesis of sound cards from Creative Labs. The first
sound card, which was able to use soundfonts, was the Sound Blaster
AWE 32 with E-MU8000 chip. It was introduced in 1994. In 1996, the
soundfont format 2.0 appeared which offered numerous innovations.
Since that, Creative Labs promotes soundfonts as an open standard.
That means that everyone may contribute solutions that support the
format. In 1998, the soundfont format was enhanced to version 2.01.
However, it had its breakthrough first at the end user with the
Audigy series which appeared in 2002. In 2005, format 2.04 was
introduced with the Sound Blaster X-Fi series. It offers the
possibility to produce samples in 24 bit.
The following
sound cards are compatible to soundfonts:
- Sound Blaster
AWE 32/64
- Sound Blaster
PCI512
- Sound Blaster
Live! series
- Sound Blaster
Audigy series
- Sound Blaster
Extigy and Audigy 2 NX
- Sound Blaster
Audigy 2 ZS notebook
- Sound Blaster
X-Fi series
In order to use
soundfonts that are larger than 100 MB in Windows, you should apply
the following entry in the registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory
Management] "PagedPoolSize"=dword:ffffffff
Alternatively,
one can download the following file and then double click it:
Soundfonts.reg
In order to
produce soundfonts yourself, you can use Vienna
SoundFont Studio (it is shipped
with Creative Soundblaster cards). It is suitable to edit existing
soundfonts as well. However, it requires a sound card by Creative
Labs. If you have a different card, you can use the program
Viena
instead.
The Creative
SoundFont-Bank-Manager is also useful.
With it, one can not only load particular instruments, but
move instruments from one soundfont to another as well. It is also
suitable to change the dynamic soundfont cache. The latter is
especially important with very big soundfonts (over 100 MB).
One can produce
and edit MIDI songs with the program Cubase SX
3. Particularly,
it is suitable to listen to single instruments of a MIDI file. This
is useful if you like to compare the effect of several soundfonts
with each other.
