However, this is not why logic's automation is smooth.
All logic automation is simply MIDI data.
The volume faders are only quantized as 7 bits, if you 'view as number'
rather than 'view as dB' you will see that the faders range from 0 to 127.
Internally Logic uses an interpolation algo to smooth parameter changes.
Many parameters in logic have only 127 steps available.


As another example, consider a volume mute. This is only ONE step. If 
it is not smoothed there will certainly be a loud 'click' or 'pop' in 
the audio.
