Reason tutorial working with midi

Hi there

Bought a bunch of these excellent tutorials
And I was about to watch the one on working with midi.Could not help notice when you play the tutorial.
The is a Chapter 1 working with Midi and a Section one working with Midi

Without sounding stupid,should there be additional sections to Chapter 1?
As Hollins Jones seems to go straight into the first part of section 1,with reference to what he has already done
I have used the update button as well
Any help would be appreciated

Just a quick update

I have realised that the tutorial working with Midi follows on from Reason fundementals ,he,he
So all sorted out

Must be a senior moment,ha,ha
