When creating MIDI messages on a sequencer or personal computer, what procedure should you use?
When creating MIDI messages on a sequencer or personal computer and transmitting them, use the following procedure.
How is exclusive data received at MIDI IN A and B?
In the same way as with channel messages, exclusive data received at MIDI IN A is passed to Group A Parts, and exclusive data received at MIDI IN B is passed to Group B Parts. In other words, exclusive data for the 32 Parts is received using two MIDI IN connectors. If this is done, each MIDI IN receives exclusive data for 16 Parts, so it is not necessary to split up the data into addresses 40 00 00 and 50 00 00.
How can the SC-88 receive exclusive data for all 32 Parts at a single MIDI IN?
However it is also possible for the SC-88 to receive exclusive data for all 32 Parts at a single MIDI IN. In this case it is necessary to use address 50 00 00. For example, the data at starting address 40 00 00 will be passed to Group A Parts, and the data at starting address 50 00 00 received at the same MIDI IN will be passed to Group B Parts. In other words, using starting address 50 00 00 means that the data will be passed to the Parts of the other Group than the.
When will exclusive data not be transmitted from the MIDI OUT connector?
Be aware that exclusive data will be not transmitted from MIDI OUT connector if the MIDI OUT/THRU select is set to THRU.
What is MIDI?
MIDI stands for Musical Instrument Digital Interface. MIDI devices can transmit musically related data such as performance data or data to select sounds. Since MIDI is a world-wide standard, musical data can be sent and received between devices even if they are of different types and were made by different manufacturers. In the MIDI standard, data describing a musical performance such as "play a note’ or “press the pedal” are transmitted as MIDI messages.
Do you need to know about MIDI to simply play commercially available music data or to provide sound for game software?
As long as you are using the SC-88 to simply play commercially available music data or to provide sound for game software, it is not necessary to know about MIDI. Simply follow the instructions in the manual for your music data playback device (MIDI player) or your software.
How are MIDI messages transmitted and received?
MIDI messages are transmitted and received using three types of connector.
What does a Modulation (control change number 1) message control?
This message controls vibrato.
What does a Volume (control change number 7) message control?
This message controls the volume of a Part. When this message is received the volume of a Part will change.
What does an Expression (control change number 11) message control?
This message conveys volume changes. It can be used to add expression during a song.
What affects the volume of a Part?
The volume of a Part will be affected both by Volume messages (control change 7) and by Expression messages (control change 11). If a value of 0 is received for either of these messages, the Part volume will be 0 and will not rise even if the other message is sent with a higher value. Be aware of this.
What is the Master Volume (Universal System Exclusive) message?
This is an exclusive message common to all MIDI devices that controls the master volume of all Parts.
What are the other exclusive messages that the SC-88 can receive?
The SC-88 can receive GS format exclusive messages (model ID 42H) that are common to all GS sound generators. The SC-88 can also use exclusive messages (model ID 45H) that are especially for the SC-88. Exclusive messages can be used to store SC-88 settings or to make fine adjustments to parameters.
Where can you find details of the exclusive messages transmitted and received by the SC-88?
For details of the exclusive message transmitted and received by the SC-88, refer to the explanation on p.7-21 and following.
What is a MIDI Implementation Chart?
