Troubleshooting

■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. ("Editing the parameters" (p. 31))

●It is possible that the parameter settings of the SD-80 have become corrupted.

Please initialize the sound generator. ("Switching the sound generator mode (Inst Initialize)" (p. 50))

*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. ("Polyphony and voices" (p. 18))

■Exclusive messages are not received

●Does the device ID number of the transmitted exclusive data match the device ID number of the SD-80? ("Setting the Device ID Number" (p. 51))

●Is the checksum correct?

For details on the calculation method, refer to the section “How to calculate the checksum” within “MIDI Implementation” (MIDIImp_E.pdf) on the included CD-ROM.

■When connected to your computer via USB, sound generator parameters are not output from the MIDI connectors

●If you are using USB mode, the MIDI connectors of the SD-80 will function as a MIDI interface for externally connected MIDI devices. The data from the computer will be output from the USB connector, and not from the MIDI connectors. This means that sound generator bulk data or individual data cannot be transmitted from the MIDI connectors.

If you are not using a USB connection, the MIDI connectors are used to exchange MIDI messages directly with the SD-80. A data request received from the MIDI IN connector will be transmitted to the MIDI OUT connector.

■When connected to your computer via USB, data is not output to MIDI OUT 2

●If you set the MIDI OUT/THRU switch to the [IN1 THRU] position while the SD-80 is operating in USB mode, the MIDI messages input to the MIDI IN 1 connector will be retransmitted without change from the MIDI OUT 2 connector.

At this time, the MIDI OUT 2 connector cannot be used for output, even though it is recognized by the computer.

■Sequencer software does not play the MIDI sound generator connected to the SD-80

●Of the music data received at the SD-80’s USB connector, the data assigned to the outputs “SD-80 MIDI OUT 1” and “SD-80 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.
