Yamaha DX7 II FD, Authorized Product Manual

Memory Types
As you can see from the diagram on the facing page, there are many facets to the Memory
layout of the new DX. To understand all of these types of memory, study the diagram and
read the explanation below:
Voice & Performance Memory
This Memory block includes data for 64 Voice Memories and 32 Performance Memories,
plus one System Setup Memory and two User-defined Micro Tunings.
System Setup Memory
System Setup Memory contains a number of basic MIDI settings, plus Master Tuning and
Cartridge Bank number settings. System Setup is always retained in Internal Memory,
along with the Voice & Performance Memory and the two User-defined Micro Tunings.
For more information on System Setup Memory, see Section 6 of this manual.
Micro Tuning Memory
The DX contains eleven Micro Tunings as part of its permanent memory. In addition, two
User-defined Micro Tunings are stored as part of Voice & Performance Memory. Using a
RAM cartridge, it is also possible to store up to 63 Micro Tuning Memories.
Fractional Scaling Memory
Fractional Scaling data cannot be stored in the DX's Internal Memory. In order to use
Fractional Scaling data with Internal Voice Memories, the data must reside in a RAM (or
ROM) cartridge installed in the DX's cartridge port.
Initialized Memory
For those who wish to create Voice Memories or Performance Memories from scratch, the
DX provides both Voice and Performance “blank Page” data as part of its permanent
memory. If you want to start from ground zero (instead of working from an already-
existing Voice or Performance Memory), call up the DX's Init Voice or Init Performance
data (using button 14 in Edit Mode).
