Why you should read this Chapter
This chapter contains some details and background theory about how Cubase VST
handles audio and MIDI, as well as some terminology used throughout this manual
and in the program. Please take the time to read this, as it will aid you in using the
program in the most effective way (when working with audio, you should also read
the chapter “Optimizing Audio Performance” for best results).
Audio Channels vs Tracks
Many audio recording systems do not make a difference between audio channels
and Tracks, which is the way a regular tape recorder works: one channel - one
Track. Cubase VST however, has a much more flexible approach to handling audio,
as we shall see. This is important to note, especially if you have previously been
working with a system where Tracks and Channels are one and the same thing.
Tracks
An Arrangement can contain a practically unlimited number of Tracks. Each Track
has a Channel (Chn) setting that determines which audio channel the Track records
and plays back on, just like you select MIDI Channel for a MIDI Track. The possi-
bilities are:
• A single (mono) channel, for example “7”.
• A stereo pair, for example “3+4”
• “Any”.
All these alternatives are described below.
Audio Channels
An audio channel plays back one
mono
audio recording at a time.
In Cubase VST, the number of audio channels you have access to is limited by your
computer’s processing power, the amount of free RAM and the speed of the hard
disk (see page 356).
The number of audio channels puts a limit to how many audio recordings can be
played back at the same time. For example, in a four channel system, you could
play back:
• One lead vocal recording (one channel), plus
• One backing vocal recording (one channel), plus
• One mono bass recording (one channel), plus
• One mono guitar recording (one channel)...
...all at the same time.
