This will enable you to use any interactive MIDI software and apps: quickly record virtual instrument tracks; write your own songs and music; learn to play and more.

The MIDI Keyboard or Digital Piano is often the heart of a small home recording studio, and the easiest and fastest way to enter bass lines, edit drum tracks, and of course record keyboard tracks.

There are THREE main ways that you will be able to connect your digital piano or keyboard up. It will depend on your keyboard. You can connect your keyboard if it has any of: traditional MIDI ports; a USB (sometimes labelled as USB host); or maybe even bluetooth. Here is a quick video which covers all the aspects of how to connect your MIDI keyboard to your iPad, Mac or PC, whether it has MIDI ports, USB or Bluetooth. Scroll down below if you want more detail, and links to the products mentioned.

Check the outputs on your keyboard. Does it have MIDI ports? MIDI (Musical Instrument Digital Interface) is the protocol for communication between your keyboard and your computer. When you press a key the action is registered by the software you are using through the MIDI link.

Most traditional keyboards and Digital Pianos have MIDI in and out as standard. Look for ports like the one in the image below. It is possible your keyboard is only a controller, and may only have MIDI out. That’s OK. The principal of MIDI connection is still the same.

So if you have a keyboard with MIDI ports, then the simplest and cheapest solution is a USB-MIDI interface. The following are all highly recommended USB-MIDI interfaces which will do the job easily and cost-effectively.

We advise that you always stick with a well-known brand which is why we recommend any of the above. They all have good manufacturer support, up-to-date drivers and good guarantees in the event of any problems. If you want even more choice, then you can follow this link to find the current top 10 most popular MIDI interfaces.

Rather than just sticking with solving the MIDI connection, if you want to make high quality audio recordings too, then you could purchase an Audio Interface with MIDI i/o and a pair of MIDI leads. Here are two really reasonably priced, and high quality options:

If you want to connect your keyboard to your iPad, and it has the MIDI ports as shown above, then you have 4 different ways to do it. Options 1 and 2 are identical to the solution for PC and Mac. You buy either a USB-MIDI interface OR a USB Audio Interface with MIDI input and output (so any of the products shown above) and use a lightning to USB adapter (as shown to the left). It is very important you buy one that allows you to charge at the same time … or you will not have sufficient power!

Got an iPad? Then you should be able to connect with a standard USB cable and a lightning to USB adapter (as mentioned above).
OR, to connect to iPad you could buy the Voker Midi Cable to Lightning Connector. This is an interface especially designed to connect from the USB output of a digital piano to ipad, via lightning.

Some manufacturers are now including Bluetooth audio/MIDI support for connecting your keyboard with your smartphone or tablet. For example, the Roland Go:Piano and Roland Go:Keys both have bluetooth – use them with any compatible apps on your iPad or smartphone.

Although you can get other kinds of MIDI controller, the keyboard is the most popular, widely available, and reasonably priced. If you have not yet got any kind of keyboard, then look first at Getting started – choosing the right keyboard. It will help you decide the best MIDI keyboard for you. You will find almost all modern keyboards and pianos feature USB MIDI connections.
If you not only want to use your keyboard or digital piano as a MIDI controller, but also want to record the sound of it, then do look read our post on how to record your keyboard. Or refer to our complete step-by-step guide on how to record audio and MIDI tracks simultaneously.

There are lots of recommendations in there for kit that will let you do BOTH. And put your keyboard right at the heart of your home recording studio. Or … see the Focusrite 2i4 and the Audiobox iTwo USB Audio/MIDI interfaces mentioned above.

Why do MIDI IN jacks connect to MIDI OUT jacks? Surely it makes more sense to connect a MIDI IN jack to a MIDI IN jack. After all, they’re both labeled IN. Same goes for MIDI OUT to MIDI OUT”

The accepted way actually makes a lot of sense. Think about it. You want MIDI data to go out of your controller and in to your sound module. After all, you wouldn’t connect the audio out jack of your sound module to the outputs of your mixer, would you? No, you connect the audio output to an audio (mixer) input. And then you connect the mixer outputs to the inputs of your amplifier. And then you connect the amp’s speaker outputs to the speaker inputs. Same thing with MIDI. Think of MIDI data as “flowing” in the same way that audio signals “flow” through your audio system.

This is just a quick guide if you simply want to hook up your keyboard to start using MIDI software. If you want a more in-depth set of tutorials, or you want to record the sound of your keyboard then you can either refer to our quick guide on how to record your piano, or see our full length free video course which explains the difference between MIDI and Audio in detail and shows you step-by-step exactly what you need to either record your keyboard or use it as a MIDI controller.
