INFORMATION ON THE UPDATING OF THE MUSICAL DATA AND OPERATIVE
SYSTEM OF THE G-70
This document is meant to try and clarify on the various modes of updating the data and operative
system of the G-70.
The operative system and boot program are included in the 64 M bit Nor Flash
IC82 TC58FVM6B2ATG65.
The musical data are stored in the 512 Mbit Nand Flash IC81
TC58DVM92A1TG00BBH.
The Nand flash is treated as a virtual drive by means of a Disk Operative System.
Before using it, it has to be formatted as a normal drive. The formatting also creates a
directory needed for the functioning of the G-70.
The data (user program, built-in styles, songs, etc.) are stored in the instrument’s memory
under the form of files.
The data’s structure is made by the following directories:
-Chain contains the files for the Play List
-Db contains the files for the database
-Demo contains the files of the demo
-Midiset contains the files of the MIDI Set
-Put New MusicAssistant Here to import new Music Assistants
-Put New Styles Here to import new Styles
-Put New Song Here to import new Songs
-ROMStyle contains the factory styles (built-in styles)
-Song contains the user songs
-Style contains the user styles
-Text contains the texts
-Update to update the instrument
-Userprg contains the files of the User Programs
It is possible to access this structure by connecting the G-70 to a PC fitted with win98ME,
Win2000/XP, MAC by means of a USB cable:
-Connect the G-70 to a PC by means of a USB cable.
-Press the switch MENU.
-Press the button “USB DATA STORAGE” on the touch screen.
-Press “INTERNAL MEMORY”: a new G-70 virtual drive will be added on Computer
Resources.
-Double-click the icon of the drive will show the G-70’s internal structure.
