Going that route one might say that in 16-bit audio the highest
frequency that can be reproduced is about 0.7Hz at 96ksps because it
takes that much time to do a full cycle over all possible values.
The example didn't use 1LSB steps at any point AFAIR. The fastest
possible MIDI PitchBend update rate is about 1.5kHz, and that's assuming
Runing Status, or about 1kHz with status byte sent at all times.
In fast modulation such resolution is not that important, but if for
example you like to detune 2 oscillators by a tiny bit to get desired
beating rate, this is not possible with only 7-bit value and huge tuning
range at the same time.
