chord track and tools

Hi Everyone

So,in between working my day job.I have been having a great time learning about Cubase and its features etc :smiley:

Now as a not very good keyboard player (wish I was though,ha,ha) How can chord track and the assistant help me with my notes and chords to sound great and fit together well ?
I have also seen somewhere,where if I were to play a wrong note,Cubase will highlight that,for me to correct it :question:
And heard about Live transform too,but not yet fully understood this.

Had looked in the online manual but not really sure where to start.Will have a look over some Cubase tutorials and Greg Ondo tutorials
Would like to learn chords and notes etc,via the circle of fifths and the proximity tool feature
Any advice would be appreciated,thanks :smiley:
