02 Digital Multitracks There are two types of digital multitracks.
These use a hard disk like a computer does.
This will give you lots of tracks to play with but you'll have limited memory.
Once the hard disc is full, you'll either have to start deleting your work (!) or buy a back up device for a couple of hundred more quid, that you can use to transfer some of your music onto.
To get round this, other digital machines work on removable media such as MiniDisc or a JAZ drive.
It's a trade-off, these machines won't run out of space - you just use a new disk for every song.
But they run slower than multi-tracks that use a hard drive which can seriously limit the number of tracks you can record and play back simultaneously.
There is a limit on the amount of data that you can fit on a single disk.
Most will quote you this figure as the 'mono track time.' That's the total amount of audio you could record as one long track.
Let's say the figure quoted is 16 minutes. If you want to record four instruments, then you can record four minutes of each. If you want eight, then you're down to two minutes.
