The patch is in attachment, and in patchstorage.com : MIDI mouse controlling effects - V1 | Patchstorage
A first démo is also available : https://youtu.be/ktCnWbMTIJA

Other ideas are of course welcome! Other tests are coming of course ;o)
How can we make calculus like this 128* x with basic modules in VCV Rack? Can’t find such a modules… Alain
That seams to be perfect as usual 
I will study this module because I need this type of calculator in my toolkit…
Thank you! Alain
And I’m sure after having a look at the documentation that could help me in generating Sysex series in MIDI port.
Can’t find a way to calcul this h14 bits value, even with Stochastic Telegraph BASICally. I have to return to the MIDI technical spec!
Thank you for your message. I just try to understand MIDI stuff around VCV Rack. Different inputs, output, modules (including yours!), interfaces between MIDI controllers and VCV.
But I have some difficulties to construct something with the 14 bits values. I understand the concept, but I can’t have a patch which create some values (LFO, CV from a knob, binary or hexa values, etc.), manipulate it, sens it thru MIDI, and decode it on the other side. I have values on the other side, but they are not the right one.
By this time, I discover many new great module in VCV!
Typically my example with 14 bits mouse. At the output on the other side, I can’t get a 14 bits with VCV’s modules…
If you have an exemple… 
Regards. Alain
Please forgive me if this is redundant or no longer accurate, but this very old topic addresses the historical complexity of supporting 14-bit messages.
ppl here tell me it’s not longer ambiguous, but I don’t know if the midi spec was modified, or of there is some unwritten convention that disambiguates it.
Reading… Thank you! Alain
Thanks to your link, I fount an important and precise explanation in this response. From @ Schabbes. I’ll test that tomorrow morning 
Thank you for this clue! Alain
What a huge exchange!
