NRPN

Hi everyone, I am trying to use NRPNs to control sound parameters through FL Studio, but it isn't working.  Please see the attached image, which explains what I've set up.  What am I missing?

 

I am using the MIDI DIN-5 cable, not the USB, if it matters.  My Sys. Setting > MIDI > Rx Filter are all set to "off."  (Confusingly, "on" means "don't respond" and "off" means "do respond.")

Nevermind, I figured it out.

 

The trick is that the NRPN number MSB and LSB are seven-bit numbers, so a standard hex-to-decimal conversion gives the wrong answer!

 

MSB 3F = binary 011 1111

LSB 00 = binary 000 0000

NRPN number = binary 011 1111 000 0000 = 01 1111 1000 0000b = 0x1F80 = decimal 8064
