Of course, at least one machine control mapping
must exist before this operation can be carried out.
1. Press and hold down the SHIFT key and the
numeric CLR key.
2. Press the numeric key corresponding to the
map you want to use (0 through 9).

The DM-24’s transport control keys will now control
the device selected in that map and the other mapping
features will also be enabled.
The MAP field at the lower part of the screen shows
the currently-loaded map.
