Importing Wavetables with more than 64 waveforms
The modwave, like many other wavetable synths, crossfades between waveforms in real-time. Some popular wavetable
software uses a different approach; instead of crossfading, they create a series of intermediate waveforms and then
just switch between them. If the differences between the intermediate waveforms are small, it sounds close enough to
a crossfade. To transition between two waveforms, they might create a Wavetable with the first waveform at the start,
254 intermediate waveforms, and then finally the second waveform at the end. To transition this smoothly between 64
different waveforms, they would need to create over sixteen thousand intermediate tables!
The modwave, on the other hand, needs only the 64 original waveforms to create a completely smooth, stepless
crossfade. This is kept in mind when importing wavetables. If a 32-bit/2048-sample wavetable has more than 64
waveforms, the modwave will assume that it's a generated crossfade and drop some of the intermediate waveforms to
create a 64-waveform version.
Creating and editing Wavetables
For creating and editing your own Wavetables, we suggest using WaveEdit. WaveEdit is free, and available for MacOS,
Windows, and Linux. See www.korg.com for a link to a version of WaveEdit which is optimized specifically for the
modwave, and can create Wavetables in the 32-bit/2048-sample format.
The Editor/Librarian can export modwave-format Wavetables, just like Performances, Programs, etc. However,
exported Wavetables cannot be edited. Instead, to make edits to previously imported custom Wavetables:
1. Open the source file in your Wavetable editing application.
2. Edit the Wavetable as desired.
3. Save the results to a new .wav file, using the same name as the Wavetable in the modwave's database.
Using the same name is important; see "Duplicates and file names, " below.
4. In the modwave Editor/Librarian, Import the .wav file as a Wavetable.
5. When prompted, choose to replace the existing Wavetable.
This will automatically update any existing sounds to use the new version.
Duplicates and file names
.wav-format Wavetables don't have modwave UUIDs until after they've been imported into the database (see "UUIDs"
on page 13). So, to check for duplicate files, the modwave uses the name of the .wav file on disk. If you import a .wav-
format Wavetable file, and it has the same name as a Wavetable already in the modwave's database, the Editor/Librarian
will ask if you want to overwrite the existing Wavetable, or make a new, unique Wavetable instead.
Backup and restore
Backing up all data
1. In the File menu, select the Backup... command.
The Main Window will change to show the Backup window.
2. Enter a brief descriptive note.
3. If desired, enable the Include User Sample Bank option.
If this box is checked, the current User Sample Bank will be included in the backup file. Note that this can significantly
increase both the size of the backup file (up to 4 GB!), and the time required to complete the backup.
4. Press Start to begin the backup, or Cancel to return to the Main Window.
A progress bar shows the status of the backup, and a message appears when the backup is complete.
5. Press the Done button to return to the Main Window.
Restoring data
Important: Restoring from a backup will delete all of the data currently in the modwave. If a subset of the data
types is selected during the restore, only the data of the selected types will be deleted.
1. In the File menu, select the Restore... command.
A standard file open dialog will appear.
2. Select the modwave backup file to use for the restore.
