The Nmedit/Nomad project needs your help. |

Hello everyone,
we have difficulties understanding the meaning of the midi message which identifies the nord modular synthesizer because we have not enough sample messages.
A small java application is attached to this posting which will retrieve this message from your Nord Modular Keyboard, Nord Modular Rack or Micro Modular. It would be a great help if you take a few minutes to fill out the form and post the results here.
You can start the application by either single/double click on the file IAMtest.jar or by using the terminal:
| Code: | | java -jar IAMtest.jar |
After you retrieved the message and filled out the form post the results here. Example:
| Code: | ------ begin ------
device: Nord Modular Keyboard
expanded: no
serial: MA 99041015
iam: F0 33 00 06 01 03 03 00 07 77 00 F7
------ end ------ |
Thank you very much,
Christian

------ end ------
really don't know what happened to the serial number plate, it's just not there ... guess it's $023d ... but it has a label on the inside saying :
OK Jonas
98-04-05
the main board is version 1.0, the expansion has version 0.2

Just for completeness I know of two other IAm messages, here are their unknown bytes 8-11
| Code: |
unk1 unk2 unk3 unk4
0x00 0x0D 0x2D 0x01 (Nord Modular rack, expanded=yes)
0x00 0x27 0x6A 0x02 (Micro Modular) |
I am pretty sure now that the fourth unknown byte has following meaning:
| Code: | 0x00 Nord Modular Keyboard
0x01 Rack
0x02 Micro |
The first byte is always zero in the four sample message we have here. It could be a reserved byte.
The questions is what the meaning of the unknown bytes 2-3 is. I believe that there we can find a bit which says whether the modular is expanded or not.

Ok, I removed the expansion :
| Quote: | ------ begin ------
device: Nord Modular Keyboard
expanded: no
serial: <not>
iam: F0 33 00 06 01 03 03 00 02 3D 00 F7
------ end ------
|
So there is no bit for it I guess.

Hm yes, I agree.
The serial number could have following structure
DD YYMMNNNN
DD = device identifier : MA=Modular (if not a coincidence)
YY = Year
MM = Month
NNNN = mysterious number
If you look at my serial MA 99041015 : then NNNN = 1015(dec) = 3F7(hex) ~ = 0777 (hex,0-bit inserted at bit8 according to MIDI spec)
This is the same value as the unknown bytes 2-3 in my IAM message.

Too good for a coincidence  and too bad I don't have a serial number

We could just keep bumping this until someone with a serial number feels guilty

Here's from mine:
------ begin ------
device: Nord Modular Keyboard
expanded: yes
serial: MA 99010818
iam: F0 33 00 06 01 03 03 00 06 32 00 F7
------ end ------

Thank you, perfect. So the unknown bytes 2-3 are the last four digits of the serial number:
06 32 (hex) = (332 removed 8th bit) = 0818 (dec)

It seems there are no more examples coming. Well, I think I know enough now. Again thanks to Antimon and especially to Jan (you are always so supportive )

Chresan, just in case you needed more:
------ begin ------
device: Micro Modular
expanded: no
serial: MC 99072012
iam: F0 33 00 06 01 03 03 00 0F 5C 02 F7
------ end ------ |
