User manual ROLAND GI-20 GK-MIDI

[. . . ] Owner's Manual Thank you, and congratulations on your choice of the Roland GI-20 GK-MIDI Interface. Before using this unit, carefully read the sections entitled: "USING THE UNIT SAFELY" (page 2­3) and "IMPORTANT NOTES" (page 4). These sections provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, owner's manual should be read in its entirety. [. . . ] Therefore, if the same assign settings are used for both of the patches prior to and following the switch, the status of the controllers is carried over. However, if the assign settings are different for the patch you are switching to, you cannot restore the value for the Control Change transmitted with the earlier patch. 20) The Note messages input to the sequencer don't look like the scale that is actually played To start playing sounds rapidly and achieve smooth changes in pitch, the GI-20 transmits pitch as a combination of Note messages and Pitch Bend messages. This means that if only the Note messages are examined on the sequencer's microscope (event list) screen, the on-screen information may differ from what is actually performed. If continuous pitch change is not required, you can create data that is displayed more faithfully by setting the BEND RANGE to "Chromatic Type 1­3. " (p. 23) 36 Chapter 5 Appendices Error Messages If you attempt an incorrect operation or if an operation could not be executed, the display will indicate an error message. Refer to this list and take the appropriate action. fig. 05-01 fig. 05-04 Reason Reception of bulk data in the Bulk Load screen was immediately followed by reception of subsequent bulk data, so the data received after by the GI-20 could not be processed. Switch the screen for a moment, then select the Bulk Load screen again and retransmit the bulk data. In case of transmitting the bulk data more than twice, please make sure that the previous data was firmly received and transmit another data. Reason The data transmitted from the GI-20's USB connector was not received by the connected computer, preventing the GI-20 from processing transmissions. Confirm that the USB-connected device is capable of receiving the data properly. Action Action fig. 05-05 fig. 05-02 Reason The GI-20's MIDI IN connector received many MIDI messages at once, and the GI-20 was unable to process the data. Reduce the amount of MIDI data transmitted to the GI-20's MIDI IN. Reason There was an error in the bulk data received in the Bulk Load screen. Switch the screen for a moment, then select the Bulk Load screen again, and transmit the bulk data again after correcting the data to transmit to the GI-20. Action Action fig. 05-06 fig. 05-03 Reason [SELECT] was pressed while exclusive data was being transmitted via the computer's USB connector, so the exclusive data could not be received properly. The sound module or other device connected to the GI-20's MIDI OUT may not be operating correctly. Turn off the power to the sound module or other device, then turn it back on again. Reason 1 The GI-20 stopped processing due to an attempt to transmit numerous MIDI messages from the GI-20 at one time. (The GI-20's MIDI IN/OUT connectors may be connected with a single MIDI cable. ) Action 1 Check the connections. Reason 2 Soft Thru on the sequencer connected to the MIDI IN/OUT is set to ON. Action 2 Set the sequencer's Soft Thru to OFF. Action 37 Chapter 5 Appendices Roland Exclusive Messages 1. Data Format for Exclusive Messages Roland's MIDI implementation uses the following data format for all Exclusive messages (type IV): Byte F0H 41H DEV MDL CMD [BODY] F7H Description Exclusive Status Manufacturer ID (Roland) Device ID Model ID Command ID Main data End of exclusive ·One-way transfer procedure (See Section 3 for details. ) This procedure is suited to the transfer of a small amount of data. It sends out an Exclusive message completely independent of the receiving device's status. Connection Diagram Device A MIDI OUT MIDI IN 1 2 Device B MIDI IN MIDI OUT Connection at point 2 is essential for "Request data" procedures. (See Section 3. ) ·MIDI status: F0H, F7H An Exclusive message must be flanked by a pair of status codes, starting with a Manufacturer ID immediately after F0H (MIDI version 1. 0). ·Handshake-transfer procedure (This device does not use this procedure) This procedure initiates a predetermined transfer sequence (handshaking) across the interface before data transfer takes place. Handshaking ensures that reliability and transfer speed are high enough to handle a large amount of data. Connection Diagram Device A MIDI OUT MIDI IN 1 2 Device B MIDI IN MIDI OUT ·Manufacturer ID: 41H The Manufacturer ID identifies the manufacturer of a MIDI instrument that sends an Exclusive message.
