Addresses Transmitted by Panel Operations
The following addresses are transmitted when you operate the panel in EXT mode.
(
*1
): This is transmitted when you press a pad (it is not transmitted when you
release the pad). It is not transmitted for NOTE TRIG.
■
Other Addresses Received
For addresses marked by #, the data is divided into multiple pieces for reception.
Example: for Beat = 32
32 is expressed in hexadecimal as 020H. 020H is divided as [00H 02H 00H].

Calculation of the Checksum of Exclusive
Messages
Roland Exclusive messages (RQ1, DT1) are transmitted with a checksum at the end
(before F7) to make sure that the message was correctly received.
The value of the checksum is determined by the address and data (or size) of the
transmitted exclusive message.
❍
How to calculate the checksum (hexadecimal numbers are
indicated by “H”)
The checksum is a value derived by adding the address, size and checksum itself
and inverting the lower 7 bits.
Here’s an example of how the checksum is calculated.
We will assume that in the exclusive message we are transmitting, the address is aa
bb cc ddH and the data or size is ee ff gg hhH.
aa + bb + cc + dd + ee + ff + gg + hh = sum
sum / 128 = quotient ... remainder
128 - remainder = checksum
(However, the checksum will be 0 if the remainder is 0.)
The SP-606 will process the data even if the received checksum is incorrect.
