But that would likely cost you just as much as an audio interface. You could go and fit a new sound card to your computer or PC. This will result in latency (lag time from when you play a note to when it actually records), sound interference and generally a lot of frustration. Even most modern laptops and PCs don’t have sound cards, off the shelf, that can cope with a synth plugged straight into it. This is one of the most important things about the interface. An audio interface is essential for most people to record a synthesizer (or other instruments) to a computer as it contains an external sound card.
