Pianists with limited power sockets
You play a virtual piano on a computer and want a keyboard that receives both MIDI data and power through the same USB connection. Check that your computer’s USB port is suitable.
If you don’t want to use an extra power socket for your keyboard, choose a model whose manufacturer confirms that the same USB connection carries both MIDI data and power. Then decide whether 88 keys with hammer action, 88 semi-weighted keys or a more compact keyboard better suits your playing space and preferences. Also check your computer, software, audio output and any pedal connection.
You play a virtual piano on a computer and want a keyboard that receives both MIDI data and power through the same USB connection. Check that your computer’s USB port is suitable.
You want a full range of keys and are comparing hammer action with semi-weighted keys before considering extra DAW controls.
You want to control a software piano but don’t have enough room for 88 keys, or you’re choosing a smaller keyboard by design.
Choose this option if: full range and hammer action are your priorities.
Consider: check that you have enough room for a full-size keyboard.
Choose this option if: you want 88 keys and prefer a semi-weighted feel.
Consider: semi-weighted keys are not the same as hammer action.
Choose this option if: available space matters more than having 88 keys within easy reach.
Consider: octave buttons don’t give you the same physical range at once as 88 keys.
| What to consider | What should you check? | Who is this important for? |
|---|---|---|
| USB power | Check that the manufacturer confirms both USB power and USB MIDI, and that your computer’s port is suitable. | I want to use the keyboard without connecting a separate mains adaptor. Around 36% of consumers prioritise powering the keyboard without an extra socket. |
| Key action and range | Compare the number of keys and the specified action for the exact model; also check the pedal input. | I want a full range for piano playing and an action that suits my preferences. Around 29% of consumers give key action and range top priority. |
| Software and audio | Check the operating system, software requirements, USB MIDI settings and audio output. | I want my computer to send the notes I play to my virtual piano and play the sound. Around 21% of consumers put software compatibility first. |
| Space and key range | Measure the available space and decide whether you want 61 or 88 keys. | I’m short on space and can manage with a smaller range of keys within easy reach. Around 14% of consumers make saving space their top priority. |
USB power can remove the need for a separate adaptor for the keyboard, but it doesn’t mean your computer, tablet or audio equipment won’t need its own power supply. Roland also notes an exception to bus power with the Lightning connection described; Nektar reports problems with inconsistent USB power in the Impact series.
Check the whole setup: keyboard, computer or tablet, audio output and any hub. Check the power and connection requirements for each device.
According to their manufacturers, the Arturia and Novation models mentioned have semi-weighted keys, while the Roland and M-Audio models mentioned have hammer action.
Check the action of the exact model and, if possible, try the keys before you buy.
A MIDI controller sends notes to software or other equipment; it doesn’t produce the sound of a virtual piano on its own.
Before you buy, check that you have suitable piano software and that your audio output is set up.
For the A-88MKII, Roland lists 88 keys with hammer action, pedal inputs and USB-C bus power.
According to M-Audio, the Hammer 88 Pro is a USB-powered model with 88 keys and hammer action. The Keystation 61 MK3 offers 61 keys with USB power, according to the brand.
According to Arturia, the KeyLab Essential 88 mk3 combines 88 semi-weighted keys with USB-C power and controls.
According to Novation, the Launchkey 88 MK4 has 88 semi-weighted keys, DAW controls and a USB-C port for data and power.
According to Nektar, the Impact LX88+ has 88 semi-weighted keys and DAW controls, with power supplied via computer USB or an optional 9V power supply.
No. The MIDI controllers discussed here send MIDI data to a device such as a computer. You’ll need a software instrument set up and an audio output to hear what you play.
No, it depends on the combination of keyboard, tablet and adaptor. Roland specifically states that bus power for the A-88MKII isn’t supported with the Lightning connection described for an iPhone or iPad; Roland recommends the optional PSB-1U mains adaptor for this setup. Check the connections for your own devices.
First, check the USB cable and port, then select the correct MIDI input in your software. Arturia describes this software setting for the KeyLab Essential mk3; Nektar mentions issues with inconsistent USB power in the Impact series.
It depends on the model and how you want to play. M-Audio lists USB power and a sustain input for the Keystation 61 MK3; the sustain pedal mentioned is sold separately. Follow the instructions for the exact model when choosing a power supply.
No. According to the European Commission, CE marking is only required when applicable harmonised EU rules specify it. The manufacturer is responsible for compliance; the rules that apply to a particular model and whether it complies with them must be assessed separately.
