When a sound is first sampled, that sample is referred to as a Tone. In order to use a Tone, it must be assigned to a Patch. A Patch consists of one or more Tones, each mapped to a key or range of keys across the keyboard. In Edit Mode, the Patch PRM page contains parameters that determine how the Tone(s) will respond when played. To create a Patch, you must first load or create a Tone (or a number of Tones).

Use the following procedure to load Tones on the S-330/550:

1. Highlight "MODE" and press the left mouse button.
2. Highlight "DISK" and press the left mouse button.
3. Highlight "FD LOAD T" and press the left mouse button.
4. Insert the disk containing the desired Tone(s) into the S-330/550's disk drive.
5. Highlight the Tone number displayed next to "FD T #" and use the left/right mouse buttons to select the Tone you wish to load.
6. Highlight the Tone number displayed next to "Int T #" and use the left/right mouse buttons to select a destination for the Tone in the S-330/550's internal memory.

NOTE: If you select a destination Tone that is not empty, the Wave data for the current Tone will be replaced by the Wave data for the Tone you are loading. Any Sub Tone that uses Wave data of the previous Tone will also be deleted, becoming an empty Tone (see Section IV for more information regarding Sub Tones).

7. Highlight "COM" and press the left mouse button. "FD Load Tone" will be displayed.
8. Press the left mouse button to begin loading the Tone.
9. Repeat steps 4-8 to load additional Tones as desired.
