Master Keyboards (up to 25 Keys) by the numbers

Median $103 — half of all master keyboards (up to 25 keys) here cost less.
median of 23 models · 0.4 kg–2.3 kg
How to choose the best master keyboards (up to 25 keys)
Key Action
This is HUGE. Expect synth-action keys - lighter and faster than weighted piano keys - which is fine for synths but can feel a bit disconnected for piano emulation. The better ones will still have some resistance and a decent amount of travel to avoid feeling like you're just pressing buttons.
Aftertouch
At this price point, dedicated aftertouch (pressure sensitivity after you press the key) is rare. Don't expect it. But some models might offer velocity curves that can simulate some of that feel - it's not the same, but it can help.
Knobs and Faders
The more you get, the more control you have over your virtual instruments. Look for encoders that feel solid and don't wobble, and remember that a few high-quality knobs are better than a dozen cheap, scratchy ones.
Build Quality
Plastic is the norm here. Look for a unit that feels solid, not flimsy. A wobble in the chassis while you're playing can be distracting and indicate cheaper internal construction.
MIDI Connectivity
USB is standard, but check if it supports MIDI over USB (class compliant) for easy connection to computers and mobile devices. Some might offer sustain pedal input - a real plus for piano sounds.
Buying guide
So, you're looking for a compact controller - a master key - to trigger those massive synth sounds or lay down some tight basslines without breaking the bank? Under $500 for a decent 25-key controller is doable, but you gotta know what to expect. We're not talking about flagship boutique instruments here; these are workhorses for bedroom producers, gigging musicians on a budget, and anyone who needs portability without sacrificing too much playability.
Realistically, at this price, you're making trade-offs. You won't get wood keys or a premium feel. Focus on key action and knob quality - those are the things that will impact your playing the most.
Don't get lured in by a ton of features if the core playing experience feels cheap; a controller is only as good as how it feels under your hands.

Questions
Are the keys going to feel like a real piano?
No. Almost all of these are synth-action, which means they're lighter and faster. They're great for synths and pads, but not ideal for nuanced piano playing. If you need a piano feel, you'll need to spend more.
Can I connect a sustain pedal?
Most can, but double-check the specs. A sustain pedal is almost essential for piano sounds, so it's a worthwhile feature to look for.
What's the deal with velocity sensitivity?
Velocity sensitivity determines how loud a note plays based on how hard you hit the key. It's important for dynamics - making your playing sound expressive. Cheaper models might have limited velocity ranges or feel inconsistent.
Will this work with my iPad?
Probably! Look for MIDI over USB (class compliant) support. You might need a USB camera adapter, depending on your iPad model.
Is there a big difference between brands?
There are subtle differences. Arturia and Akai generally have a reputation for solid build and reliable MIDI implementation, but you can find gems from other brands too. Read reviews and watch videos to get a feel for the specific model.
