Hi everyone,

I’m very new to sysex dumping and parameter updating, while not new to programming and midi. 

The NoteWeaver music app I’m developing needs to download voice names from the Motif-Rack XS while being selected during Multi mode MSB/LSB/PC updates.  (among other up and downloaded items in the future)

Looks like I need to first update the MSB/LSB/PC, which will select a specific voice, then I can bulk dump the 20 characters of a voice from within the MIDI PARAMETER CHANGE TABLE (NORMAL VOICE COMMON), which seems logical and simple enough.

However from the terse explainations on pages 60 - 63 (including the p63 Bulk Dump Block explaination) of the Data List manual, which I’ve gone over and over and over, I don’t quite get the big picture on how to extract, and update the synth data.

I see the following sysex commands:

“NATIVE PARAMETER CHANGE, MODE CHANGE”,
“BULK DUMP”, “DUMP REQUEST”, and
“PARAMETER REQUEST”

-- Looks like one or more of these is the ticket.

Is there a short, clear, explaination somewhere on how these commands work?

For instance, is the Native Parameter Change, Mode Change bidirectional?  Is this for updating only 1 piece of synth information at a time?  And what does the word Native mean?

Then does the Dump Request request a dump that’s returned by the Bulk Dump? or is the Bulk Dump simply bidirectional? —I’d expect there to be a bulk dump INTO the rack and a bulk dump FROM the rack, each using a byte count, start address, and checksum—perhaps that’s how the Bulk Dump DOES work???

Then the last one—Parameter Request: I see the request address, but how does the data get fed back? —and is it a single parameter?  And what does the above “Native” word mean? and does it apply here?

Thank you for any help, Looks like a great site!
