To create a patch of your own (or modify an existing patch), you use the following basic steps:
1. Click the folder button for a drum sound channel.
The Redrum sample browser opens.
2. Locate and open a drum sample.
You will find a large number of drum samples in the Factory Sound Bank (in the folder Redrum Drum Kits/xclusive drums-sorted). You can also use any AIFF, Wave, SoundFont sample or REX file slice for this.
3. Make the desired settings for the drum sound channel.
4. Repeat steps 1 and 3 for the other drum sound channels.
5. When you're satisfied with the drum kit, you can save the patch by clicking the Floppy Disk button in the patch section on the device panel.
Note however, that you don't necessarily need to save the patch - all settings are included when you save the song.
Loading slices from within a REX file is done much in the same way as loading "regular" samples:
1. Open the sample browser (the folder button for a drum channel).
Possible extensions are ".rex2", ".rex" and ".rcy".
3. Select the file and click "Open".
The browser will now display a list of all the separate slices within the REX file.
