Reading the
Menwry Layout Diagram
Complete descriptions of the memory types, listed below, are provided earlier in this
guide. Notice that these memory types make up the other main sections of the Memory
Layout diagram.
• Fractional Scaling memory
• Voice memory
• Performance memory
• System Setup memory
• Micro Tuning memory
• Current Play/Edit memory
• Compare/Recall memory
• Initialized memory
In the Memory Layout diagram, the dark vertical arrows indicate how "blocks" of
memory are moved between media types.
For example, look at the Fractional Scaling Memory column. The dark arrow indicates
that Fractional Scaling data for 64 voices may be moved, as a block of memory, between
a disk (in the FD) and a RAM cartridge. The arrow is double-headed indicating that this
block of data may be moved in either direction (from cartridge to disk as well as disk to
cartridge).
Next, look at the Disk row. Notice the box around Voice, Performance, and System Setup
memories. This means that these memory areas are moved together. You may, for
example, move this block of memory in either direction between a disk and internal
memory. This block of memory always contains the following data:
• 64 voices
• 32 performances
• 2 user microtuning scales
•System setup data (at your option)
Now, look at the Internal Memory row. The box in the Micro Tuning Memory column
refers to the user micro tuning scales
moved along with the Voice, Performance and the optional System Setup memories.
The two small dark arrows indicate that this same block of memory can be moved
between disk and cartridge. It may also be moved between Cartridge and Internal
Memory.
The last dark arrow on the right of the page illustrates that a block of 6 3 Microtuning
scales may be moved between disk and cartridge.
