Owner’s Manual We’d like to take a moment to thank you for purchasing the SCB-55 GS Daughter Board. The SCB-55 is a daughterboard containing high-quality sounds compatible with the GM (General MIDI) System and GS Format. In order to gain a thorough understanding of the SCB-55’s many features, please take the time to read this manual carefully. -
Page 2: Features
FEATURES Easy Installation All you need to do is to mount the SCB-55 onto a sound card compatible with Sound Blaster, and you can enjoy high-quality sounds with music or game software. 16-part Multi-Timbral Sound Generator The SCB-55 is a 16-part multi-timbral (including the drum part) sound generator. It can play up to 28 notes simultaneously, making possible ensembles of up to 16 parts. -
Page 3: Installing The Scb-55
Remove your sound card from the expansion slot of your computer. Connect the Extension Connector (your sound card may call it “the MIDI Connector”) of the SCB-55 to your sound card as shown below. Be sure to properly and securely attach the SCB-55. -
Page 4: The General Midi System And Gs Format
GS Format The GS Format is a standardized set of specifications for Roland’s sound generators which defines the manner in which multi-timbral sound generating units will respond to MIDI messages. The GS Format also complies with the General MIDI System. -
Page 5: Structure And Function Of The Scb-55
Voices, the maximum number of notes you could play at once would be 14. To determine how many Voices the SCB-55 is using, add up the number of Voices used by all the Parts. Note that it is possible to have all 28 Voices working to produce the sound of only one Part. -
Page 6: Maximum Polyphony
Exclusive messages (p. 26). Part Priority When the SCB-55 receives performance data which request it to produce more than the 28 Voices available, priority is given to producing the most recently received note mes- sages. -
Page 7: Chorus And Reverb
* Although Program Numbers range from 1 to 128, there are nowhere near that many dif- ferent Drum Sets on the SCB-55. If you try to select a Drum Set that doesn’t exist, you’ll get no sound when you try to play. Check the DRUM SET TABLE (p. 19) to make sure that the Program Change message you are sending corresponds to an actual Drum Set. -
Page 8: About Midi
4. ABOUT MIDI MIDI stands for Musical Instrument Digital Interface. MIDI is a world-wide standard that allows musical instruments and computers to exchange musical data. Most electronic musical instruments sold today are MIDI compatible. MIDI compatible devices have MIDI connectors which are used to physically link instruments (using special cables). MIDI does not transmit the sound of an instrument, but rather ‘messages’... -
Page 9: Midi Messages Handled By The Scb-55
SOUND Canvas The SCB-55 is capable of simultaneously recognizing the MIDI messages on all 16 chan- nels. In other words, it is capable of playing 16 different Parts at the same time. Of these, the Part which is set to receive on MIDI channel 10 is known as the Drum Part. This Part provides a collection of percussive instrument sounds, with a different sound for each Note Number (p. -
Page 10: Control Change Messages
These messages are generally used to change tones. The tones are selected with Program Numbers 1 to 128. In the SCB-55, the Tone can be changed using Program Change messages. If a Bank Select (Control Change message) is used with a Program Change, more Variations can be selected. - Page 11 GS Format, the data will not be played as expected. To play song data from a different manufacturer, set the “NRPN Reception Switch” to OFF. When the SCB-55 receives a “GM System ON,” it will automatically turn the “NRPN Reception Switch” off.
- Page 12 System Exclusive messages can be used for all devices - regardless of the manufacturer. General Exclusive messages, however cannot convey data between different models. Roland’s Exclusive messages have a unique manufacturer ID, device ID, and model ID so that the type of data can be determined.
-
Page 13: Default Settings
This is a common universal Exclusive message for controlling the master volume of all parts. •Other Exclusive Messages The SCB-55 responds to GS Universal System Exclusive messages (as specified by the GS Format) so its settings can be controlled by software or external controllers that also con- form to the GS Format. -
