Saving a sound confusion

I am confused by how you move the sound you have saved to an empty slot in the sound bank??? After I save the sound (3) I cant do (4) it just attenuates the sound.

it reads

Saving Sounds

  1. Select a track with sound to store by pressing [
    Trk 1], etc
  2. Press [FUNCTION] + [KEYB D1] i.e. Sound
  3. Select SAVE TRACK SOUND press [Yes/Save]
  4. Use (LEVEL) control or [<] [>] buttons to browse
    to sound slot (max 128)
  5. Select [Yes/Save] to store to highlighted sound
    slot

(Save)+(Sound) will save to an empty slot of +Drive

Thanks

So say you have banks ABCDEG full will the sound save to F001?

Sorry just a bit lost here.

That’s how it plays out in my experience, it goes to first available slot. ‘Fast’ kit saving just overwrites current kit though
