Nord Lead 2 proper MIDI data

[Prober]

Hello to all Nord Lead/Rack 2/2x owners.

Now I'm trying to create an app what can transmit the patch sysex (.syx) dumps to .xml patches (they serve as patches in Renoise Guru tool Custom Nord Lead 2 definition interface).

I somehow stuck on sync/ringmod/distortortion putch dump format (described in original manual).

It says - size - 1, offset - 52, bit 0 = sync on/off, bit 1 = ring mod on/off, bit 4 = filter dist on/off...

First - I listed many ram/rom patches of my NR2X and found no one patch what enables sync and ring at the same time (althoug you can select it by button from front pannel)..

Trying to understand dump structure and examining a few patches I found what at 52th offset in sysex dump:

00 00 - all is off (sync off, ring off, dist off)
01 00 - sync on
02 00 - ring on??? (never seen in patches - just conclusion)
03 00 - ring+sync??? (never seen in patches - just conclusion)
00 01 - dist on
01 01 - sync on dist on??? (never seen in patches - just conclusion)
02 01 - ring on dist on
03 01 - ring on sync on dist on??? (never seen in patches - just conclusion)

Is this correct?

I do not have that synth, but I guess that you are right.
To me is easier to imagine it as dip switches which are independent of each other:
6543210: bit
0000000 all off
0000001 sync on
0000010 ring on
0000011 sync on, ring on
0010000 dist on
0010001 dist on, sync on
0010010 dist on, ring on
0010011 dist on, sync on, ring on
Since there are some of the bits which are not used, I guess that those are just ignored. Maybe it is just a coincidence that no patch has those particular combinations that you have not seen.
This picture has the three on!:

The thing is all the factory Programs are NordLead(1), the original, made, which doesn't have the Ring Modulator nor the Distortion
I don't know how one has to read the SysEx, but I know all parameters and configurations (switches) are as [00 00] in hex.
I have played with it a couple of years ago...

Here is what I found...

Doc file part one is the complete Program SysEx wiyh only 1 parameter or switch at full value.
Doc file part two is the next parameter.

The SysEx file is devided in two. The first part (after the glabal data) are the knobs, the second part in the file are the buttons.

All was performed on a NordLed2.
Hope it is of some use...

So that is the reason they are never there

I don't know how one has to read the SysEx, but I know all parameters and configurations (switches) are as [00 00] in hex.

Yes, you are right, MIDI dump are usually shown in hex. But the hex notation is convenient for certain things and not for others. In this case because each parameter is controlled by one bit (and MIDI sysex messages are encoded in chunks of 7bits) the binary format is seems more intuitive to understand how to pack the 3 parameters (or at least it is for me ). By looking at the binary pattern you see which ones are on and off. For sending MIDI velocity, hexadecimal or better just decimal (0-127) seem (to me) more intuitive.

Wow Mr_-G-, you mean you don't automatically do the translation between hex and binary in your head? I'm soo disappointed.

Well... nobody is perfikt!
