Yamaha DX7s, Owner'S Manual

Page: 71 / 108

System Setup Memory
System Setup Memory contains most of the basic MIDI 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 DX7s 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
DX7s 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).
Current Play/Edit Memory
Whenever you call up a Voice Memory or Performance Memory in Play Mode, you are
actually sending it to a special location in the DX7s — the current Play/Edit Memory. As
the name indicates, this is also the location where Voice or Performance data is edited. In
computer terminology, this memory location is often called the Edit Buffer.
Compare/Recall Memory
When you are editing a Voice or Performance and use the Edit/Compare feature, the
original Voice data is loaded into the Play/Edit Memory (so you can hear it). The edited
Voice data is moved temporarily into another memory location, the Compare/Recall
Memory. In computer terms, this memory location might be called the Compare Buffer.
When you engage the Recall Edit function for the various Internal Memory types, you are
actually recalling the last data moved to the Compare/Recall Memory.
