Controlling the SD-90 via MIDI
The functionality of the SD-90’s internal sound generator, mixer, and audio effects can be controlled by
MIDI messages received from the USB connector or MIDI IN connector. This chapter provides various
examples that show how MIDI messages can be used to operate the SD-90.
*
For details on operation via MIDI, refer to “MIDI implementation” (MIDIImple_j.pdf) on the included CD-ROM.
Controlling the internal sound generator
MIDI messages can be used to control the internal sound generator.
■
Switching the sound generator mode
You can use MIDI messages to switch the sound generator mode. Transmit one of the following messages
according to the desired sound generator mode. When you switch the sound generator mode, the sound
generator will be initialized.

Features of Native mode
Native mode allows you to take full advantage of the SD-90’s sound generator structure. Use this mode
when you want to edit the internal sounds or MFX in greater detail. Although this mode lets you control
parameters that cannot be edited in other modes, operations in Native mode are not compatible with
GM2. In other words, song data created in Native mode cannot be reproduced by playing it back on
another GM2 sound generator.

• In Native mode, MFX and sounds (instruments) can be handled independently. For this reason, simply
selecting an Enhanced sound will not automatically cause MFX to be applied. You will need to edit the
part parameters in order to apply MFX.
• You can also apply effects to sounds other than the Enhanced set, or input the signals from multiple
parts into a single MFX.

For details on using MFX, refer to
