How to choose the best synthesizer peripherals
Build Quality
Cheap plastic is common at this price. Look for sturdy knobs, reliable jacks, and a chassis that won't rattle apart on stage. A flimsy build screams 'replacement needed soon.'
Latency
MIDI controllers are useless if there's a noticeable delay. We're talking about milliseconds here, but that lag can kill your feel, especially when playing fast lines or triggering complex sequences.
Connectivity
USB is almost universal, but check for MIDI DIN ports if you're connecting to older gear. Thru ports are also a nice bonus for chaining controllers.
Expressiveness
Keybed feel is critical. Heavier keybeds offer better velocity sensitivity, but lighter ones can be easier to play quickly. Aftertouch, assignable knobs, and pads all add to the expressive potential.
Software Integration
Some peripherals come with software editors or bundled software. While often basic, these can be handy for tweaking settings and mapping controls, especially if you're diving into deep synthesis.
Buying guide
Alright, so you're deep in the synth rabbit hole, but your budget's not deep enough for that Jupiter-X. You need to expand your sonic palette without breaking the bank. These aren't just accessories; they're the things that can transform a decent synth into a gig-ready powerhouse - and we're keeping it under $300. Let's talk about making those synths sing.
At this price point, expect compromises. The keybed won't feel like an 88-key stage piano, and the build quality won't be boutique. Prioritize the features you need - if you're primarily a bass player, a good pad controller might be more valuable than a full-sized keyboard.
Read reviews carefully and look for user feedback on reliability - cheap gear often has frustrating quirks.

Questions
What's the deal with velocity sensitivity?
Velocity is how hard you hit a key - it affects volume and other parameters. Better keybeds have a wider velocity range and more nuanced response. A cheap keybed might feel 'flat' and less dynamic.
Can I use these with my DAW?
Almost certainly, yes. MIDI is a standard. Make sure your DAW recognizes the peripheral. Some come with basic mapping software, but you'll likely need to configure things in your DAW's MIDI settings.
Are these controllers good for sequencing?
Absolutely! Pad controllers are fantastic for drum programming and creating rhythmic patterns. Keyboards are great for playing melodies and chords, and can be mapped to control synth parameters. It's all about creative routing.
What about sustain pedals? Do they need to be expensive?
Not necessarily. A basic, universal sustain pedal will work with most synths and controllers. You won't get the nuanced response of a higher-end pedal, but it's a solid, budget-friendly option. Just make sure it's a "continuous" pedal, not just an on/off switch.
I'm worried about latency. Is there anything I can do?
Latency is a common issue. Ensure your USB connection is stable, and adjust your DAW's buffer size. Lower buffer sizes reduce latency, but require more processing power - find the sweet spot that doesn't cause audio dropouts.
