If the SC-88ST part monitor indicator does not flash, MIDI messages are not being received from your MIDI keyboard. Check your MIDI keyboard settings and MIDI cable connections. * With the initial settings, the SC-88ST will produce sound in response to any channel 1 — 16, regardless of the transmit channel your keyboard is set to. This is because each Part is assigned to the correspondingly numbered MIDI channel. The number below the part monitor indicator is the Part number. Headphones Use headphones of 8 — 150 ohms impedance. Sound will be output from the audio output jacks even when headphones are connected. Audio input jacks You can connect the output jacks of other MIDI sound sources to these jacks. The audio signal that is input here will be mixed with the SC-88ST sound and output from the audio output jacks. 2)(2)r ÏNPUT OUTPUT MADE IN JAPAN О i(o oil ((o 0)1 ((о о)] О VSPftCJJ XsPnO/J vVooO/y w Fnr^ BO t t SC-88ST HI о о Sound Module Chapter 1. Try out the SC-88ST 9 Chapter 2 Using the SC-88ST from a personal computer Using the SC-88ST from a personal computer The SC-B8ST can be controlled by music software running on a personal computer. This will allow you to create your own songs, and also to select sounds or edit sounds from the computer display. This type of system is known as a Desk Top Music System (DTMS). The functions provided by a DTMS differ widely depending on the software, so it is important that you choose software suited to your needs. Connections with your computer There are two ways to connect the SC-88ST to your computer; using the MIDI connectors or the COMPUTER Connector. If you use the MIDI connectors, you will need to obtain a computer interface board (adapter) that has MIDI connectors (such as the Roland Super MPU, etc.). If you use the SC-88ST COMPUTER Connector, you can use a special cable to connect it directly with the computer, but your software must be able to correspond to the serial port. If you wish to connect your computer via the MIDI connectors, refer to p. 11 (Connecting a computer via the MIDI connectors) for how to make connections. The following explanation will show how to make connections using the SC-88ST COMPUTER Connector. ■ Connections 1. Turn off the SC-88ST power, and set the COMPUTER Switch located on the back of the SC-88ST. Note The Computer Switch will be validated when the power is turned off and then on after the setting has been made. * The setting will depend on the type of computer you have and the software you use. The PC-1 baud rate is 31.25K (bit/sec), and the PC-2 baud rate is 38.4K (bit/sec). Set the COMPUTER Switch to the baud rate required by your MIDI application (software). Carefully read the manual for your software regarding the switch setting. In general, set the switch to Mac for Macintosh series computers, and to PC-2 for IBM PC/AT series computers. 2. Connect the COMPUTER Cable to the RS232C connector or modem port located on the back of your computer. 3. Connect the other end of the COMPUTER Cable to the SC-88ST COMPUTER Connector (COMPUTER). 4- Turn on the SC-88ST power. Caution when using the SC-88ST with the IBM PC/AT series Even if the SC-88ST COMPUTER Connector is connected to your personal computer, it will not operate correctly if the software (MIDI application) is incompatible. Be sure to use software that is compatible with the serial port of the personal computer. COMPUTER cable (designed for IBM PC/ATs and compatibles) 10 Chapter 2.
