Latency is the main problem music producers encounter when recording audio tracks and working with VST instruments. It's an unwanted delay we should get rid of straight away, before we start working with music.
In case you missed the link in our previous lesson, here it is again Asio4All Sound Driver - you should download this driver and install it. No special tweaking is required.
I'm mentioning the MIDI keyboard in this lesson, and that is something we'll cover in one of our upcoming lessons. It's not necessary to have one, but it does help you with composing and recording.
Good luck and rock on!
