[fluid-dev] fluidsynth increase one semitone

[Nadal Gonzalo García Zavala]

Hi.
   I just bought a midi keyboard (midplus 61).

   It works well. However seems there is no obvious way to transpose it a semitone (up or down), in contrast to other midi controllers which have this specific option.

   I basically want to play and record along with my guitar tuned at 432hz.

   So my question is: Is there a way to tell fluidsynth to increase a semitone / change the pitch ?

i'm a bit confused, there is too much technical info which i'm not sure if may help to my situation.

Is there a midi (Control Change ?) message capable of doing this ?

How other midi controllers interact with fluidsynth when they are setted to 432 ?

Thanks
