[. . . ] ALESIS M20 System Exclusive Fourth Revision August 5, 1999 ALESIS PDAT SYSTEM EXCLUSIVE The PDAT responds to all Alesis system exclusive ADAT commands, as well as MIDI Machine Control (MMC) commands. [. . . ] Note <#data bytes> must equal <24 Bit Address> must equal 0. 2. Repeat the <#data bytes> <24 Bit Address> <data byte 1> . . <data byte N> sequence for programming of additional flash locations. Note that the <24 Bit Address> specifies the start of programming location for the specified <data byte>'s. Always complete the end of the transmission with the checksum sequence above. If <type> is 2, 3, 6, or 7 (data with interleaved checksum) then [data] is: <#data bytes> <24 Bit Address> <data byte 1> . . . .
