For example, to send an Arpeggiator Header block for the Multi Part1 Edit buffer, the SysEx string would be:
Address Patch Format
When Addr1 ID is 01~08 for accessing data dumps, Addr2 ID is used to select if a single patch or all patches
are sent:
So to request that all Arpeggiator Data is sent, the SysEx string would be:
Address Index Format
When Addr1 ID is 08~10, which are used to access parameters within a patch, Addr2/Addr3 are used to supply
14-bit offset into the patch.
For example, the SysEx string to request that Multi parameter number 180 for part2 be sent would be:
The data value is sent as a 14-bit number, so the response SysEx string to store 0x2FF would look like:
