Fractional Scaling
Memory Description
Microtuning Memory
Description
On the original DX7, Level Scaling allowed a change in timbre or volume across the
keyboard. It offered a choice of level-scaling curves and variable depth.
The DX7 II provides a much more :flexible method of level scaling called Fractional
Scaling. Using Fractional Scaling, the output level of each individual operator can be
varied in 3-key groups so you can create virtually any level or timbre curve. The
accompanying diagram illustrates this feature's effect.

Each bar in the above diagram represents an operator output value for a 3-key group. For
example, you may want to set operator
6
output level to equal
62
in the range C#3 to D#3.
From E3 to F#3 the same operator's output level may equal 87.
This may be set individually for each of six operators. A lot of memory is necessary to
store all of these values. Therefore, the Fractional Scaling data for a voice must be stored
separately from the voice itself. You will learn how to store these values so they may be
accessed when you select a particular voice. For now, just remember that even though this
data is selected (recalled) along with a specific voice, it is stored separately from the voice
itself.
The DX7
II
provides
11
preset Microtuning scales. These are always available because
they are permanently stored in the DX7 II memory.
Additionally, the DX7
II
allows you to create your own microtuning scales. Consult the
appropriate Supplement Guide for detailed instructions on how to do this.
Once you have created a scale, you may store it in one of two User Programmed scales. If
you want to create more than two scales, they may
be
stored on a cartridge or a disk. The
microtune function will allow you to access additional scales from a cartridge. Step-by
step instructions for storing and accessing additional microtuning scales
will
be described
later in this guide.
