Summary0008396: MIDI Bender is [-2,+2] semitones and not [-4,+4] as the documentation claims
DescriptionThis is the documentation:

https://manual.ardour.org/working-with-midi/automation-midi/

It claims the midi bender range is [-4,+4] semitones, however, it seems to be [-2,+2].
Steps To ReproduceUse a-Fluidsynth on an MIDI track (I have not tested other synths).

Select a soundfont (I tested Aspirin_160_GMGS_2015.sf2 and Jurgen_GM_GS_Bank.sf2).

Create a midi area and put a B4. Now, open automation on Bender, and raise it to 16383.

Now, listen, you'll get a C#5 instead of a D#5.

There is no rule about the range of the MIDI bender.

It's different for each synth and in some cases also different for different voices of a synth.
The MIDI spec leaves this undefined. The range is set by the soundfont for each instrument.

I've updated the manual page. Thanks for the heads up!
