CTK-671 MIDI Implementation MIDI Device ID is a Patch Parameter data item, and it can be changed using a System Exclusive Message. In such a case, the Device ID of the MIDI System Exclusive Message must be set to 7FH before it is sent. 2.1.1 CTK-671 System Exclusive Message + ------------- Individual Parameter Transfer -- + -- Command - + - Version + - DSP 5/6 ....
CTK-671 MIDI Implementation Each block of data is packed from the lowest order byte first. In the case of multiplebyte data, the lowest weighted bit is the LSB of the first block, and the highest weighted bit is the MSB of the final block. The following shows an 10 ..... ps : Parameter Set Number Format : 0nnnnnnn, 0mmmmmmm (LSB, MSB) example of how data would be divided for transfer in the case of 32-bit data.

CTK-671 MIDI Implementation Mixer settings, synthesizer function, DSP function and other editable parameters are also included in this function. The contents of this area are rewritten whenever preset data or user data is selected. Note, however, that voices that are already sounding are maintained.
