How to choose the best synthesizer peripherals

Keybed/Action

A heavy, synth-action keybed makes a huge difference in expression. Expect compromises at this price-weighted keys are a long shot, but a decent semi-weighted or synth action is achievable. It's about feel, and how well it translates to the sounds you're trying to create.

Expression Pedals

These aren't just for volume swells. Think filter sweeps, modulation depth control, aftertouch - essential for adding movement and life to your patches. Look for reliable, quiet pedals with good responsiveness.

MIDI Interfaces

Reliable MIDI is the backbone of any modern setup. Low-latency performance is critical, especially when sequencing or using external effects. Avoid cheap interfaces - dropouts and timing issues are a nightmare.

Sustain Pedal

A decent sustain pedal is non-negotiable. A heavy-duty switch and reliable contact closure are key. Avoid the cheesy plastic ones that feel like they'll break after a few gigs.

DAW Integration/Control Surfaces

Mapping controls to your DAW is a game-changer. Look for devices with solid driver support and intuitive mapping capabilities. Even basic control can massively speed up your workflow.

Buying guide

Alright, so you're knee-deep in synths but your setup feels... incomplete. Maybe your keyboard's action is a pain, or you're craving some serious expression beyond just banging on keys. We're talking about peripherals - the stuff that elevates your synth game without emptying your bank account. Under $500, you can grab some seriously useful gear - let's see what's out there.

At this budget, you're making trade-offs. The cheapest expression pedals might feel a little mushy, and MIDI interfaces can sometimes have slightly higher latency. Prioritize reliability over bells and whistles - a gear failure mid-gig is a bigger problem than a slightly less-shiny feature.

Don't be afraid to shop around and read user reviews; other players often know the hidden quirks.

How the AudioFu Index works

Five measured signals and nothing else — no stars from strangers, no “tested by experts” we didn’t do. The weights are fixed and public. We don’t play these instruments; we measure the market around them.

This chart covers 58 synthesizer peripherals from the Thomann catalogue. Before you buy, read hands-on reviews and, where you can, play it. Full methodology.

AudioFu earns a commission when you buy through our Thomann links. It never changes the order — the index does.

Questions

Can I get a weighted keybed under $500?

Realistically, no. Weighted keys are expensive. You'll find semi-weighted or synth action, which are perfectly usable but won't mimic a piano's feel.

What's the deal with MIDI latency?

Lower latency is better. Anything under 10ms is generally unnoticeable, but cheaper MIDI interfaces can easily exceed that. Driver updates are your friend.

Are expression pedals universal?

Mostly, yes. They use standard 1/4" jacks. However, some synths might require specific pedal types (e.g., continuous vs. momentary). Check your synth's manual.

What's the difference between a MIDI interface and a USB MIDI keyboard?

A USB MIDI keyboard has the interface built-in. A dedicated MIDI interface allows you to connect older gear or provides more MIDI ports than your keyboard offers.

Is it worth buying used?

Absolutely. You can often snag a higher-quality piece of gear for less by buying used. Just check for wear and tear, and make sure all the controls are working correctly.
