I am using, inside the vst~ object, a plug-in which i can (and want) 

to control by NRPN , in order to have a much more precise control

The plug-in is OHMForce's QuadFrohmage Filter ( a really great

I know how to access the NRPN number - and also how to send the 

value, but only using 2 (midi, 0-127) values

I would like to send ONE (0-16384) value...

how to translate this ONE (0-16384) value into 2 (midi, 0-127) values???

midievent messge(s).

The trouble is that I don't really know what all those NRPNs and bits

have much use for NRPN

"16384 possible NRPN's, each one
having a 14 bit value (i.e. a value between
0 and 16383). The system uses 4 prede-
fined MIDI CC's.
Data is sent to the MIDI
device in two phases : first the NRPN num-
ber, and then the NRPN value."

value, but only using 2 (midi, 0-127) values

(I kind of suspect it is close to using [<< 7] in reverse.... so it 
could be [>> 7] but.. but it's quite unclear to me - why 7, how to 
access all 16384 values, etc etc)

nrpn-bits-and-all-this

In max it could be done like below. The 7 is because midi-values are limited to 7 bits.

Here it is fairly clear explained:

I did not knew the [&] object - it now makes total sense

there was a little problem in what I originally posted, caused by the change object

128 would be decoded as 0, 256 as 128 etcetera.

o yes. that's probably the better way in this case - [& 127] instead of [% 128]. clearer, and probably a bit cheaper cpu-wise, too?

NRPN, bits and all this..
