Home producing your vocals takes some to get used to. Here’s some advice to help you out. But in the mean time, let’s talk about the microphone. If you’re recording at home, you’re probably going to use whatever mic you have lying around. So make sure to purchase something that fits with what you plan to record next time you get to the store.
The first is free-hand, which is to say that you record piano and vocals at the same time and even if they’re off tempo the two are synced together. It will sound more free and raw, but you’ll have a hard time syncing rhythmic elements and timed processing such as delay and reverb in a consistent manner. The second way is to record on grid, whereby you’ll record to a click-track to steady your tempo. In this case, it’s best to record one track at a time, but that doesn’t mean you can’t sing to yourself while you record your keyboard takes.
