Loading DX sounds
Overview
The MOD-7 can load sounds created for the vintage DX7.
There are thousands of these sounds available on the
internet, providing a massive pre-existing library of timbres
(in addition to the many sounds created exclusively for the
MOD-7!). Try searching for “DX7 SysEx download.”
Once loaded, you can bring these vintage sounds up to date
using all of the MOD-7’s unique features, layer them with
other EXi, and process them with Arpeggiator and the
NAUTILUS effects.
The conversion works by reading .SYX format System
Exclusive files. This format is supported by programs on all
major computer operating systems.
Supported file types
In order to load a file, it must meet the following
requirements:
• The file must contain a complete bank of 32 DX7
sounds. Files with only a single sound cannot be loaded.
• The file may contain multiple System Exclusive
messages, but only if the main DX7 bank dump is the
first of these messages. All subsequent messages in the
file will be ignored.
Note: Some instruments, such as the DX7II, may transmit
multiple System Exclusive messages when doing their
program data dump, with the main DX7 bank dump
coming last. If this set of messages is stored into a single
.SYX file, the NAUTILUS will not be able to load the
file.
• The System Exclusive must be in the original, first-
generation DX7 format, which was supported by all of
the classic 6-operator FM synths as well as the DX9.
System Exclusive files from later-generation FM
instruments, such as 4-operator “baby DX” synths and
the TX81Z, SY77, etc., cannot be loaded.
Loading a single bank of DX7 sounds
To load a bank of DX7 sounds:
1. Transfer the DX7 .SYX file to NAUTILUS-readable
media, such as a USB flash drive.
2. Connect the media to the NAUTILUS.
3. Press the front-panel MODE button to select MEDIA
mode.
4. Go to the Load page.
5. In the Drive Select parameter, select the media from
step 2, above.
6. Select the DX7 SYX file.
7. Press the LOAD button.
A dialog box will appear, allowing you to select a bank into
which to load the sounds. Since DX7 banks contain 32
sounds, while a NAUTILUS bank contains 128, you can also
select where to place the DX7 sounds within the
NAUTILUS bank: into Programs 0-31, 32-63, 64-95, or 96-
127.
8. Select the bank and Program range into which to load
the sounds.
Important: If you select an HD-1 bank, it will be changed to
an EXi bank, and all of the bank’s HD-1 Programs will be
erased.
9. Press OK to load the sounds.
The sounds will be loaded into the NAUTILUS as MOD-7
Programs.
Loading multiple banks of DX7 sounds
If you like, you can load multiple .SYX files at once. To do
so:
1. Follow steps 1 through 4 under “Loading a single
bank of DX7 sounds,” above.
2. Enable the Multiple Select check-box.
3. Select the desired DX7 .SYX files.
4. Press the LOAD button.
An “Are you sure?” dialog will appear.
5. Press OK.
6. For each .SYX file, select the bank and Program
range to load into.
For more information, see steps 8 and 9 under “Loading a
single bank of DX7 sounds,” above.
Error messages
If the NAUTILUS can’t read the file, it will show one of two
error messages:
There is no readable data will appear if the file is shorter
than 4104 bytes, or if the SysEx header indicates something
other than DX7 Program Bank format.
File contains unsupported data will appear if the header is
correct, but the data is damaged; for instance, if the file’s
checksum doesn’t match, or if the trailing F7 is missing.
