Hold the space bar (or a MIDI pedal) for sustain. Press a lit button again to switch it off. Click the program name to rename it, press STORE, then pick a slot (BANK cycles through banks A to H) to save, or use the Preset Library menu to jump to any sound. SAVE adds the current sound to My Saved Presets. EXPORT saves every bank and saved preset to a file, and IMPORT loads them back.
