Anleitung Zusammenfassung


17, 2000 Version: 1.10 MIDI Implementation 1. RECOGNIZED RECEIVE DATA ■ CHANNEL VOICE MESSAGE • Control Change Status BnH Second ccH Third vvH n = MIDI Channel No. : 0H - FH (ch.1 - ch.16) cc = Controller No. : 00H , 20H (0 , 32) 01H - 1FH (1 - 31) 40H - 5FH (64 - 95) vv = Value : 00H - 7FH (0 - 127) * Control numbers 00H and 20H are recognized as Bank Select messages. 2. TRANSMITTED DATA ■ SYSTEM EXCLUSIVE MESSAGE STATUS F0H Data Byte iiH,ddH...eeH Status F7H F0H = System Exclusive ii = Manufacturer ID : 41H (Roland ) dd ,..ee = Data : 00H - 7FH (0 - 127) F7H = EOX (End of Exclusive/System common) * For more details, please refer to “Roland Exclusive Message” (p. 56). 3. EXCLUSIVE COMMUNICATION 00H : For value of 00H or 01H, Program change map will be used. For values of 02H or higher, the following banks will be selected. 02H Preset A 03H Preset B 04H User A 03H User B Others : Program change map 20H : The received data will be ignored, regardless of the value. * By specifying this as a source for “realtime parameter control” you can use these messages to control a target. * Program Change Status Second CnH ppH n = MIDI Channel No. : 0H - FH (ch.1 - ch.16) pp = Program No. : 00H - 7FH (No.1 - No.128) * Patches will be selected according to the program number that is received. ■ SYSTEM REALTIME MESSAGE Status F8H ON the VF-1, exclusive messages can be used as follows. -Transmit/receive VF-1 system/patch data The model ID for VF-1 exclusive messages is 00H 23H, and you can set up the device ID at 00H- 1FH. ■ ONE WAY COMMUNICATION • Request Data1 RQ1 (11H) Byte Description F0H Exclusive Status 41H Manufacturer ID(Roland) Dev Device ID (Dev=00H-1FH) 00H Model ID (VF-1) MSB 23H Model ID (VF-1) LSB 11H Command ID(RQ1) aaH Address MSB bbH Address ccH Address LSB ssH Size MSB ttH Size uuH Size LSB sum Checksum F7H EOX (End of System Exclusive) * This message can only be received, and is not transmitted from the VF-1.

On VF-1, The data of Exclusive communication is in 4bit nibbles. Divide the value of DATA section by that of SIZE section. Example: Set UTILITY GLOBAL BPM on 180BPM 1. Refer to Parameter Address Map to calculate UTILITY GLOBAL BPM Address. From ADDRESS BLOCK MAP, BASE ADDRESS of UTILITY BLOCK is 08 00 00H Next, from UTILITY AREA TABLE, OFFSET ADDRESS of GLOBAL BPM PARAMETER is ** 01 2CH And then, calculate the actual address. 08 00 00H BASE ADDRESS +00 01 2CH OFFSET ADDRESS 4. ADDRESS MAPPING OF PARAMETER The address and size are displayed under 7-bit hexadecimal notation. Binary 7-bit Hexadecimal AA Address 0aaa aaaa Binary Size 0sss ssss 7-bit Hexadecimal SS MSB 0bbb bbbb BB MSB 0ttt tttt TT LSB 0ccc cccc CC LSB 0uuu uuuu UU ■ Parameter base address The actual address of each parameter is the start address of the block plus the offset address. Q Address Block Map 2. From UTILITY AREA TABLE, the value when at 180BPM is calculated to be B4H. The data is in parameter's size-byte nibbles setting. From UTILITY AREA TABLE, data size of GLOBAL BPM PARAMETER comes to 4-byte. 16bit 4bit MSB LSB 0000_0000_1011_0100B 0000_0000B 0000_0000B 0000_1011B 0000_0100B B4H 00H 00H 0BH 04H 3. (1) through (7) are set according to Roland's format for Exclusive(SysEX) messages. Set the data of 4-byte above-mentioned in order from MSB to LSB. 0 8H + 01H + 2CH + 00H + 00H + 0BH + 04H В + 1 + 44 + О + О + 11 + 4 = 44H(sum) = бВ 68(sum) / 128 = 0(quotient)...6 checksum = 128 - 68(remainder) 5. From 3., 4, the message is completed. F0 41 00 00 23 12 (remainder) = 60 = 3CH 01 2C 00 00 0B 04 3C F7 ■ dummy Parameter Data set on dummy Parameter is ignored.
