The process is quite easy. Just connect your MIDI cable to the MIDI Out on the first midi keyboard, and then connect the other side directly to the MIDI IN on your second keyboard. Once you do this, you can start duplicating the sound you play on your first keyboard to be replayed on the second keyboard.

The first keyboard is known as the master, and the second keyboard is usually referred to as the slave.

Determine the roles between keyboards

Due to the vital roles of each keyboard roles, it’s essential to rightly determine which of your keyboard should be the master and which should be the slave.

The master keyboard, which is also the first keyboard, should have all the needed presets. It should also have the ability to send control signals to the slave keyboard. By just a single button press on the master keyboard, you should be able to effect a program change on your MIDI keyboards. It is important to note that the ability to control the other MIDI equipment is a significant factor to consider when choosing your master keyboard.

Make connections

After determining your master and slave keyboard, the next thing to do is connect the MIDI OUT cable from the master keyboard to the MIDI IN of the slave keyboard. It is that easy! Some keyboards even come with a USB cable for easy connection.

An example of such is the Arturia Minilab MKII inverted MIDI Controller. It doesn’t just have a USB cable. It also has some software like the analog lab lite and even a user’s manual.

If you have gotten this far, you will need to determine which data you want to send from your master keyboard to the other musical equipment. Besides, you also need to know how to transmit this data.

You can use the drum pads and the knobs together, and you may want to transfer the sound to the second keyboard while you play your keynotes on the first keyboard. This could happen if you’re going to create an orchestra effect in your music.

Making sounds

Making different sounds in your music will create an effect that will not only sound like multiple voices but will also give more life to the music. So, how do you achieve this?

On your master keyboard, you can create a program using different voices, tones, and pitches. You can then send these notes from your first keyboard to the second keyboard, or you can even combine the sounds made with extra voice again.

A midi keyboard like the Alexis V25 with its four assignable knobs and four assignable buttons will give your sound a top-notch effect. In fact, you can connect your MIDI to send information independent of other programs you’ve pre-arranged.

Extra MIDI gear

At this stage, you may be wondering what the MIDI Thru is for? Well, you can decide to add a third keyboard for a more mind-blowing effect. To include the third keyboard, you will need your MIDI Thru connector. This doesn’t mean that you can’t achieve a similar effect with your two keyboards, though.

If you don’t want to add a third keyboard, but you want to add other gears like a sequencer, a computer, or a sound module, you can also follow this process.

  • First, connect your Master keyboard to a sequencer or computer
  • Link the MIDI Out from your keyboard to the sequencer MIDI In. Then, also connect the MIDI Out from the sequencer to the MIDI In of your keyboard
  • Connect Your Keyboard to a Sound Module
  • Connect the MIDI cable to the MIDI Thru of your keyboard and link it to the MIDI In of your sound module
