Voices which were already sounding before the program change was received will not be affected. Channel Mode Messages * Following Channel Mode Messages can be received on channel specified in SETUP/MIDI/MIDI Channel. All Sounds Off (Controller number 120) Status 2nd byte 3rd byte BnH 78H 00H n = MIDI channel number: 0H - FH (ch.1 - ch.16) * When this message is received, all currently-sounding notes will be silenced. However, the status of channel messages will not change. Reset All Controllers (Controller number 121) Status 2nd byte 3rd byte BnH 79H 00H n = MIDI channel number: 0H - FH (ch.1 - ch.16) * When this message is received, the following controllers will be set to their reset values. Controller Reset value Foot Control 0 (off) Expression 0 (off) Effect Control 1 0 (off) Effect Control 2 0 (off) Appendices 119 MIDI Implementation All Notes Off (Controller number 123) Status 2nd byte 3rd byte BnH 7BH 00H n = MIDI channel number: 0H - FH (ch.1 - ch.16) * When an All Notes Off message is received, all notes that are set to “on” are turned “off” except waves in which the trigger mode is set to SHOT or ALT. System Realtime Message Active Sensing Status FEH * When Active Sensing is received, the unit will begin monitoring the intervals of all further messages. While monitoring, if the interval between messages exceeds about 420ms, the same processing will be carried out as when All Sounds Off, All Notes Off and Reset All Controllers are received, and message interval monitoring will be halted. System Exclusive Message Status Data byte Status F0H iiH, ddH, ......, eeH F7H F0H: System Exclusive Message status ii = ID number: an ID number (manufacturer ID) to indicate the manufacturer whose Exclusive message this is. Roland’s manufacturer ID is 41H. ID numbers 7EH and 7FH are extensions of the MIDI standard; Universal Non-realtime Messages (7EH) and Universal Realtime Messages (7FH). dd,..., ee = data: 00H - 7FH (0 - 127) F7H: EOX (End Of Exclusive) The System Exclusive Messages received by SPD-S are; Universal Non-realtime System Exclusive Messages, Data Requests (RQ1), and Data Set (DT1). Universal Non-realtime System Exclusive Messages .Identity Request Status Data byte Status F0H 7EH, dev, 06H, 01HF7H Byte Explanation F0H Exclusive status 7EH ID number (universal non-realtime message) dev Device ID (dev:00H - 1FH (1 - 32) Initial value is 10H (17)) 06H, 01H Identity request F7H EOX (End Of Exclusive) * Even if the Device ID is 7FH (Broadcast), Identity reply message will be transmitted. * When Identity Request is received, Identity reply message will be transmitted (Page 122). Data transmission The SPD-S supports bulk dumping/loading of patch parameters and setup parameters with the use of exclusive messages. It does not send or receive individual parameters. The exclusive message of SPD-S’s data has a model ID of 00H 67H and a device ID of 10H (17). Device ID can be changed in SPD-S. .Request data 1 RQ1 (11H) This message requests the other device to send data. When a Data Request message is received, if the device is ready to transmit data and if the address and size are appropriate, the requested data will be transmitted as a “Data Set 1 (DT1)” message. If not, nothing will be transmitted. The only data request messages that the SPD-S can receive are Bulk Dump Request messages. Status Data byte Status F0H 41H, dev, 00H, 67H, 11H, F7H aaH, bbH, ccH, ddH, ssH, ttH, uuH,vvH, sum Byte Explanation F0H Exclusive status 41H ID number (Roland) dev Device ID (dev: 00H - 1FH (1 - 32) Initial value is 10H (17)) 00H 67H Model ID (SPD-S) 11H Command ID (RQ1) aaH Address MSB: upper byte of the starting address of the requested data bbH Address 2nd: 2nd byte of the starting address of the requested data ccH Address 3rd: 3rd byte of the starting address of the requested data ddH Address LSB: lower byte of the starting address of the requested data ssH Size MSB ttH Size 2nd uuH Size 3rd vvH Size LSB sum Checksum F7H EOX (End Of Exclusive) * Regarding the checksum please refer to Page 123. * For Bulk Dump Request, you must use the Address and Size listed in the following Bulk Dump Request. Parameter Dump Request Address (H) Size (H) 70 00 00 00 00 00 00 00 (SETUP: request for all setup except Device ID and LCD Contrast) 71 00 00 00 00 00 00 00 (ALL PATCHES: dump request for all patches) MIDI Implementation .Data set 1 DT1 (12H) This is the message that actually performs data transmission. The SPD-S only receives bulk data.
