There are two main options for connecting the MIDI ports of your digital piano to your computer:

USB-to-MIDI Adapter Cable:

  • Connect the MIDI Out port on the rear of the digital piano to the MIDI In port on the USB-to-MIDI adapter cable.
  • Connect the USB end of the adapter cable to an open USB port on your computer.

MIDI Cables:

  • Connect a 5-pin MIDI cable from the MIDI Out port on the digital piano to the MIDI In port on your computer’s MIDI interface.
  • Most computers do not have legacy MIDI ports, so you’ll need a separate MIDI interface unit.

Configuring the DAW or MIDI Software

Once connected, you’ll need to setup your recording software:

  • Open your DAW or MIDI recording software on the computer.
  • In the preferences/settings, select the USB-to-MIDI adapter or MIDI interface as the MIDI input device.
  • You may need to adjust MIDI sensitivity and velocity curve settings to optimize the dynamics and expression of the digital piano.
  • Set the MIDI channel inputs to match the channels from your digital piano.

The software is now ready to receive MIDI data from the digital piano controller.

Playing Virtual Instruments with Your Digital Piano

One of the biggest advantages of using a digital piano as a MIDI controller is being able to play virtual software instruments from the keyboard. Here’s an overview:

Choosing Virtual Instruments

Most DAWs come with a selection of virtual instrument plugins including synthesizers, samplers, drum machines, and more. You can also expand your virtual instrument library through paid or free plugins from third-party developers. Consider your musical preferences and target genres when selecting virtual instruments.

GenreRecommended Virtual Instruments
Pop/RockElectric and acoustic pianos, drums, guitars
EDM/DanceSynths, drum machines, sampler
Hip-hopSampler, vinyl scratching FX, drum machines
JazzAcoustic piano, upright bass, drums, vibraphone
ClassicalOrchestral strings, woodwinds, choirs

Popular options include:

  • Piano and keyboard instruments (ex. Native Instruments Komplete Kontrol, Arturia Piano V)
  • Orchestral and strings (ex. Spitfire Audio Albion One, EastWest Quantum Leap)
  • Synths and electronic instruments (ex. Native Instruments Massive, Arturia V Collection)
  • Drum machines and percussion (ex. Native Instruments Battery, XLN Audio Addictive Drums)

Assigning Virtual Instruments to MIDI Channels

Most MIDI recording software allows you to assign different virtual instruments to specific MIDI channels. For example:

  • Set virtual piano plugin to receive on MIDI channel 1
  • Set virtual synth plugin to receive on MIDI channel 2

On your digital piano, configure the MIDI channels to match. Often channel 1 is the default. This allows you to selectively trigger different instruments from the keyboard.

Playing and Recording with Virtual Instruments

Once properly setup, you can play the digital piano keys and hear the virtual instruments through your computer speakers or studio monitors, as well as record MIDI performances to the DAW:

  • Play notes and chords on the digital piano to trigger the virtual instrument sounds.
  • Use the DAW to record your virtual instrument performances as MIDI data.
  • Edit and manipulate the MIDI data, change instruments, adjust mixing, and more.

Utilizing MIDI Features for Advanced Control

Beyond just triggering virtual notes, your digital piano MIDI controller opens up deeper creative possibilities by utilizing MIDI’s expressive capabilities:
