Something is wrong with the sound
●
You may have switched to another sound after editing sound parameters (such as the filter).
Set all sound parameter values to 0.
●
It is possible that the parameter settings of the SD-90 have become corrupted.
Please initialize the sound generator. (
"Switching the sound generator mode (Inst Initialize)"
*
The system parameter settings will be preserved even if the sound generator is initialized.
●
Are you using MFX?
If a sound that uses MFX (a sound from the enhanced set) is being played, and you switch the MFX type,
or you choose a different enhanced sound, one that uses a different effect type, the sound will continue
playing with the newly selected effect settings. Please wait until the enhanced sound has finished playing
before you change the MFX settings or select a different enhanced sound.
■
Notes are interrupted
●
If you attempt to use more than 128 voices simultaneously, notes will be interrupted.
■
Exclusive messages are not received
●
Does the device ID number of the transmitted exclusive data match the device ID number of the SD-90?
"Setting the Device ID Number"
●
Is the checksum correct?
For details on the calculation method, refer to “Calculating the checksum” in “MIDI implementation”
(MIDIImple_E.pdf) on the included CD-ROM.
■
The SD-90 does not transmit MIDI data
●
If you want to transmit SD-90 data via the USB connector, start up the SD-90 in USB mode.
MIDI data will not be output from the USB connector if the SD-90 is started up in MIDI mode.
●
If you switch on MIDI IN THRU when the SD-90 has been started up in USB mode, it will no longer be
possible to use the external MIDI output from your computer.
■
Sequencer software does not play the MIDI sound generator connected
to the SD-90
●
Of the music data received at the SD-90’s USB connector, the data assigned to the outputs “SD-90 MIDI OUT
1” and “SD-90 MIDI OUT 2” will be transmitted from the MIDI OUT 1 connector and MIDI OUT 2 connector,
respectively.
Make the correct settings in your sequencer software and in the various drivers.
■
When you turn MFX on, all of the system effects you have previously set
(such as reverb) are initialized.
●
When you turn MFX on, it will no longer be possible to use control changes to set the send level of the
system effect.
This means that when you turn MFX on, it will be necessary to send the signal to the system effect via a
different route than before.
You can use the MFX SEND LEVEL TO REVERB/CHORUS/DELAY system exclusive message to set the
system effect send level (common to the signals that have passed through the insertion effect) for when
MFX is turned ON (
