Using the internal sound generator
About parameters
This section explains the parameters (items that you can set).
Parameters
are settings that determine how
a sound is produced, and the process of modifying the values of the parameters is called “editing.”
If you are using the SD-90 in
GM2 mode
or
Native mode
, some of the Part parameter values can be
edited from the panel of the SD-90 itself. In other modes, parameter values cannot be edited from the
panel of the SD-90. However, the parameters can be edited by using the editing functionality of your
computer software or sequencer.
For details on how to edit the parameters, refer to the “
MIDI implementation
” (MIDIImple_E.pdf) on the
included CD-ROM. The adjustable range of each parameter is printed in this manual as described in the
comment column of the MIDI implementation.
Internal operation of parameters
When you select a sound, the sound data is loaded into a memory location called the “
temporary area
.”
The SD-90 produces sound based on the data in this temporary area.

When you edit a sound or drum set, you are temporarily
modifying the settings of the data in the temporary area.
It is
not possible for the edited sounds to be saved in the
internal memory of the SD-90.
Your edits will be lost when
you turn off the power. If you want to preserve the edited
state, you can either make a note of the settings, or save
them on an external MIDI device, such as a MIDI sequencer
