MIDI Data Format MIDI Data Format This section explains the format of the data that the PM5D is able to understand, send, and receive. In addition to the messages described here, you can use the MIDI REMOTE function or the MIDI EVENT settings of the SCENE function to transmit any type of command. 1 CHANNEL MESSAGE 1.1 NOTE OFF (8n) Reception These messages are echoed to MIDI OUT if [OTHER ECHO] is ON. They are received if [Rx CH] matches, and used to control effects. STATUS DATA 1000nnnn 8n Note off message 0nnnnnnn nn Note number 0vvvvvvv vv Velocity(ignored) 1.2 NOTE ON (9n) Reception These messages are echoed to MIDI OUT if [OTHER ECHO] is ON. They are received if [Rx CH] matches, and used to control effects. STATUS DATA 1001nnnn 9n Note on message 0nnnnnnn nn Note number 0vvvvvvv vv Velocity (1-127:on, 0:off) 1.3 CONTROL CHANGE (Bn) Two types of control change can be transmitted and received; [NRPN] (NonRegistered Parameter Numbers) and freely-assigned [TABLE] (16CH x 110) messages. Select either [TABLE] or [NRPN]. Reception These messages are echoed to MIDI OUT if [Control Change ECHO] is ON. If [TABLE MULTI] is selected, these messages are received when [Control Change Rx] is ON, and will control parameters according to the settings of the [Control assign table]. If [TABLE SINGLE] is selected, these messages are received when [Control Change Rx] is ON and [Rx CH] matches, and will control parameters according to the settings of the [Control assign table]. For the parameters that can be assigned, refer to p.341. If [NRPN] is selected, these messages are received when [Control Change Rx] is ON and the [Rx CH] matches; the four messages NRPN control number (62h, 63h) and DATA ENTRY control number (06h, 26h) are used to control the specified parameter. Transmission If [TABLE MULTI] is selected, and if [Control Change Tx] is ON when you operate a parameter that is assigned in the [Control assign table], these messages will be transmitted. If [TABLE SINGLE] is selected, and if [Control Change Tx] is ON when you operate a parameter that is assigned in the [Control assign table], these messages are transmitted on the [Tx CH] channel. For the parameters that can be assigned, refer to p.341. If [NRPN] is selected, and if [Control Change Tx] is ON when you operate a specified parameter, the four messages NRPN control number (62h, 63h) and DATA ENTRY control number (06h, 26h) are transmitted on the [Tx CH] channel. Control Change messages are not used for transmission to PM5D Editor because there is no guarantee that the contents of the assignment tables will match. (Parameter Change messages are always used.) Control Change numbers 0 and 32 are for selecting banks. STATUS DATA STATUS DATA 1011nnnn Bn Control change 00 Control number (00) 0vvvvvvv vv Control Value (0-127) 1011nnnn Bn Control change 20 Control number (32) 0vvvvvvv vv Control Value (0-127) If [TABLE] is selected STATUS 1011nnnn Bn Control change DATA 0nnnnnnn nn Control number (1-31,33-95,102-119) * 0vvvvvvv vv Control Value (0-127) * Numbers 0, 32, and 96-101 cannot be used. Equation for converting a Control Value to parameter data paramSteps add mod curValue = paramMax - paramMin + 1; = paramWidth / paramSteps; = paramWidth - add * paramSteps; = parm * add + mod / 2; (1) If the assigned parameter has fewer than 128 steps paramWidth = 128; rxValue = Control value; (2) If the assigned parameter has 128 or more but less than 16,384 steps paramWidth = 16384; (2-1) When High and Low data is received rxValue = Control value(High) * 128 + Control value(Low); (2-2) When Low data is received rxValue = (curValue & 16256) + Control value(Low); (2-3) When High data is received rxValue = Control value(High) * 128 + (curValue & 127); (3) If the assigned parameter has 16,384 or more but less than 2,097,152 steps paramWidth = 2097152; (3-1) When High, Middle, and Low data is received rxValue = Control value(High) * 16384 + Control value(Middle) * 128 + Control value(Low); (3-2) When only Low data is received rxValue = (curValue & 2097024) + Control value(Low); (3-3) When only Middle data is received rxValue = (curValue & 2080895) + Control value(Middle) * 128; (3-4) When only High data is received rxValue = (curValue & 16383) + Control value(High) * 16384; (3-5) When only Middle and Low data is received rxValue = (curValue & 2080768) + Control value(Middle) * 128 + Control value(Low); (3-6) When only High and Low data is received rxValue = (curValue & 16256) + Control value(High) * 16384 + Control value(Low); (3-7) When only High and Middle data is received rxValue = (curValue & 127) + Control value(High) * 16384 + Control value(Middle) * 128; if ( rxValue > paramWidth) rxValue = paramWidth; param = ( rxValue - mod / 2) / add; If [NRPN] is selected STATUS 1011nnnn Bn Control change DATA 01100010 62 NRPN LSB 0vvvvvvv vv Parameter number LSB STATUS 1011nnnn Bn Control change * DATA 01100011 63 NRPN MSB 0vvvvvvv vv Parameter number MSB STATUS 1011nnnn Bn Control change * DATA 00000110 06 Data entry MSB 0vvvvvvv vv Parameter data MSB STATUS 1011nnnn Bn Control change * DATA 00100110 26 Data entry LSB 0vvvvvvv vv Parameter data LSB * The STATUS byte of the second and subsequent messages need not be added during transmission. Reception must occur correctly whether or not the status byte is omitted. 368 PM5D/PM5D-RH V2 / DSP5D Owner's Manual Reference section
