about MIDI, please visit our Helpful Links
What's the difference
between CDs and MIDI files?
CDs play in a "regular" CD player and cannot be changed. MIDI files are
interactive data files. With a MIDI file you can change the instruments that
are playing particular parts, speed up the song without changing the key,
change the key without changing the tempo, change the number of verses and
The CD won't play in my CD
player. What's wrong?
Check the packaging to see if you have MIDI files on a CD-ROM or a CD
audio digital recording. MIDI files on a CD-ROM will not play in a CD
player. If you do have a CD audio digital recording, and it's not playing in
your CD player, give us a call.
What is MIDI?
MIDI is an acronym for Musical Instrument Digital Interface. MIDI was
originally designed to allow musical instruments to communicate. In
churches, MIDI is typically used as musical accompaniment for congregational
singing. Our CDs are used in the same way, but the advantage of MIDI is that
you can make changes to the song.
What is General MIDI?
General MIDI (GM) is the industry standard for MIDI. To play our files, you
will need equipment that is GM compatible. This will ensure consistent
playback of the MIDI data contained in the files.
What are GS and XG?
GS and XG are Roland's and Yamaha's enhanced versions of GM. All MIDI
Marvels MIDI products are GM, GS, and XG compatible.
What is a Standard MIDI
The word "standard" indicates the way in which a MIDI file is saved on a
disk. Standard MIDI files have the file extension ".mid". All MIDI Marvels
MIDI files are standard.
How do I play MIDI files?
There are a number of ways to play MIDI files. The most common are:
GM-compatible electronic keyboard with 3.5" disk drive for inserting the
MIDI disk, stand-alone MIDI player, and computer to sound module to sound
My equipment uses floppy
disks, but you sent a CD-ROM. How do I use it?
We package collections on CD-ROMs rather than individual disks for two
reasons. First, MIDI files are easily corrupted on floppy disks, and CD-ROMs
significantly reduce the risk of corrupting the files. Second, while only
six to eight MIDI files fit on a floppy disk, we can put hundreds of them on
one CD-ROM. You can place the CD-ROM into the CD drive on your computer and
copy the songs you need to a floppy disk for your service.
Are the lyrics included in
the MIDI files?
Yes. The lyrics are embedded as MIDI events on channel 4 of each MIDI file.
Do you offer a satisfaction
Music is as subjective as anything else that is artistic. We provide samples
of many of our songs so that you can hear what they sound like before
purchasing. We are happy to replace any defective product with the same
