How to choose the best master keyboards (up to 25 keys)
Keybed Feel
Forget piano-action or even semi-weighted. Expect synth-action - light, consistent resistance. Some are better than others; a mushy keybed will kill your articulation. We're looking for something that doesn't feel completely plastic.
Build Quality
At this price, plastic is the name of the game. Look for decent weight - a lighter unit often means flimsier construction. Check reviews for reports of cracking or wobbly keys.
MIDI Connectivity
USB MIDI is a must. Some might offer sustain pedal input, which is a nice bonus, but don't expect anything fancy like MIDI DIN. Reliable latency-free performance is key.
Knobs & Controls
Don't expect motorized faders or tons of assignable knobs. A few basic knobs for filter cutoff, resonance, or amp envelope are a plus, but often absent. Focus on the core keyboard functionality.
Software Integration
Does it work seamlessly with your DAW? Check compatibility lists and user forums. A frustrating setup will negate any cost savings.
Buying guide
Alright, so you're looking for a master keyboard - a small controller to trigger sounds in your DAW or hardware synths - and you're on a serious budget. Under $100? It's a challenge, no doubt. We're not talking about luxurious keybeds or endless knobs, but you can find something useful that'll get the job done for practice, basic recording, or even triggering loops at a low-key gig. Let's break down what's realistic at this price point.
Realistically, you're trading off something. Keybed feel will be the most noticeable compromise - you're not getting a buttery-smooth action. Build quality will also be a concern; treat these like they're delicate.
If you can stretch your budget even a little, you'll see a noticeable improvement in keybed quality. Prioritize a reliable USB connection and good DAW compatibility over extra bells and whistles.

Questions
Are the keys velocity-sensitive?
Most will offer some velocity response, but don't expect nuanced dynamics like a piano. The sensitivity range can be limited, and the feel can be inconsistent. It's enough for basic playing, but not for expressive performance.
Can I use it with a sustain pedal?
Some models have a 1/4" sustain pedal input, but you'll likely need to buy the pedal separately. Check the product description carefully - it's not a universal feature at this price.
Will it work with my iPad?
Almost certainly, as long as your iPad supports USB-MIDI via a camera adapter. Just make sure the keyboard is class-compliant (most are).
What's the difference between a master keyboard and a MIDI controller?
Essentially nothing! 'Master keyboard' is often used for smaller, 25-key controllers. They both do the same thing: send MIDI data to other devices.
Is it worth buying used?
Absolutely. You might find a slightly better model (better keybed, more controls) within your budget on the used market. Just check for physical damage and make sure the keys are responsive.
