required Fractional Scaling or
Micro Tuning data
is not available. When
the needed data is supplied
via a RAM cartridge,
these displays disappear.
RAM cartridges are useful storage centers for Voice & Performance data. In addition,
they are the only storage source from which Fractional Scaling data and Micro Tuning
data can be accessed for immediate use with DX Internal Voice & Performance data. To
understand the basic Cartridge Utility functions, read on.

Using Cartridge Data

Except for the two User-defined Micro Tunings that are part of the DX's Internal Voice &
Performance Memory, Cartridge Memory is the only location from which Fractional
Scaling and Micro Tuning data may be recalled for immediate use. Fractional Scaling data
and Micro Tuning data can be stored on disk, but cannot be used directly with Internal
Memory from disk: In order to interact with Internal Voice & Performance data,
Fractional Scaling and Micro Tuning data must reside in a cartridge plugged into the DX's
Cartridge port. If you create Voice or Performance data that involves Cartridge Memory
(for either Fractional Scaling or Micro Tuning), the DX will remind you as follows:
This symbol signifies that the indicated Voice Memory
was created with Fractional Scaling, but the RAM cartridge
with the necessary Fractional Scaling data is not inserted
in the instrument's cartridge port.
This symbol signifies that the indicated Performance memory
was created to include Micro Tuning from a RAM cartridge,
but the RAM cartridge with the necessary Micro Tuning
data is not inserted in the instrument's cartridge port.
