The other "HOWTO" thread was meant more for how to get started. This one I'm hoping will funnel away some of the application of Sysex - which is different from just being able to use the mechanism and follow the data list.

The latest from the other thread was the observance that H/M/L address of 00/7F/00 seems to be reported back from a bulk dump but is not documented. I have a Montage, not MODX - but my experiments have shown:

addr of 00/7F/00 parameter read returns 01 as a single byte of data.
addr of 00/7F/01 parameter read returns 00 as a single byte of data
addr of 00/7F/02 parameter read returns 00 as a single byte of data
addr of 00/7F/03 parameter read returns 00 as a single byte of data
addr for L>03 and H/M=00/7F seems to be invalid (keyboard error messages).

Trying to write to all 4 of the above bytes does not cause an error - but does not seem to change anything. Data read back is still the same as before parameter change. Conclusion/guess is that these registers are read-only. Meaning is unknown. Possible this is a flag (00/7F/00) for debug build vs. production build. That's a wild guess. I don't think there is much of interest you can do with this/these bytes.

Exactly the same thing and observations on Modx.

Reloading some old perfs from Montage and Modx my soft have saved on disk with my own format( I save all blocs I receive on disk).
It seems that bloc 00.7F.00 appears only since OS V2.0 for Modx.
For Montage I have only saved perfs with OS until V2 and bloc 00.7F.00 is absent.
