3516.3.13 data : Parameter DataParameter data indicates the parameter value.The data array is a list of len + 1 data items.For a one data item structure, the length depends on the data bit width, as shown below.Each block of data is packed from the lowest order byte first. In the case of multiple-byte data, the lowest weightedbit is the least significant digit of the first data byte, and the highest weighted bit is the most significant digit ofthe final data byte.The following shows an example of how data would be divided for transfer in the case of 32-bit data.Single Message Size LimitWith this Instrument’s system exclusive message format, the size of a single message cannot exceed 48 bytes.The data size and the array size, however, can cause a packet to exceed 48 bytes when transferring a single parameter array.In this case, the IPS and IPR message data length and data index number values can be modified to enable division of asingle parameter value into multiple messages so it can be sent that way.16.3.14 EOX : End of System Exclusive MessageThis is the End of System Exclusive Message status byte established by the MIDI standard.Format: index0 0dddddddB (0eeeeeeeB) (0fffffffB) (0gggggggB) (0hhhhhhhB)index1 0dddddddB (0eeeeeeeB) (0fffffffB) (0gggggggB) (0hhhhhhhB)index2 0dddddddB (0eeeeeeeB) (0fffffffB) (0gggggggB) (0hhhhhhhB): :indexN 0dddddddB (0eeeeeeeB) (0fffffffB) (0gggggggB) (0hhhhhhhB)dddddB + 1 Number of data1 - 7 18 - 14 215 - 21 322 - 28 429 - 32 57 6 5 4 3 2 1 0data0: 0 [bit06] [bit05] [bit04] [bit03] [bit02] [bit01] [bit00]data1: 0 [bit13] [bit12] [bit11] [bit10] [bit09] [bit08] [bit07]data2: 0 [bit20] [bit19] [bit18] [bit17] [bit16] [bit15] [bit14]data3: 0 [bit27] [bit26] [bit25] [bit24] [bit23] [bit22] [bit21]data4: 0 0 0 0 [bit31] [bit30] [bit29] [bit28]Format: 11110111B
