Clock master
Start and stop on the Clock master page on the device: OK on the Clock row, or PLAY when PLAY has no MIDI job (Button MIDI card).

Load applies at once. Save stores the settings as they are on the device, so write first. A name (12 characters, plain ASCII) is stored when you leave the box and shows on the FM-1's Presets page; clear drops it.

Backup
Import fills the form; click Write to send it to the device.
