How to choose the best sound modules
Sound Quality
This isn't about 'warmth' or 'brightness,' it's about articulation. Can you hear the individual notes? Does it have a usable low-end thump without getting muddy? Does the sustain ring true, or does it just fade out awkwardly?
Polyphony
32 voices is the bare minimum these days. Anything less and you'll be fighting MIDI limitations in a band setting. Think about layering pads or playing complex chords - you need headroom.
Connectivity
MIDI in/out is a given, but look for USB MIDI, and ideally, audio outputs beyond just a single stereo pair. Multiple outputs let you route different parts to different monitors, which is a huge help for mixing.
Build Quality
Plastic cases are common at this price point, but check for flimsy knobs or a keyboard action that feels cheap. A module that falls apart on stage isn't a good deal, no matter how good it sounds.
User Interface
A confusing menu system can be a nightmare, especially during a live gig. Look for a layout that's intuitive and easy to navigate, or at least one that's well-documented online.
Buying guide
Alright, so you're looking for a sound module without breaking the bank? Been there. Getting a decent keyboard voice without dropping a grand is totally doable, but you gotta know what to look for. We're talking about getting something that'll sound decent in a band rehearsal, won't make your home recording sound like a tin can, and maybe even cut through a live mix - all under $500.
At this price, you're making trade-offs. Don't expect boutique-level sounds or a lightning-fast, weighted keybed. You'll likely be sacrificing some nuance in the sounds and the build will be noticeably less robust.
Prioritize sound quality and polyphony - those are the features that will actually make a difference in your playing. Don't get hung up on fancy effects unless they're genuinely usable.

Questions
Can I realistically get vintage Rhodes sounds under $500?
You can get something that resembles a Rhodes, but don't expect the real deal. Many modules offer Rhodes-inspired patches, but the nuance and complexity of a true Rhodes is hard to replicate without serious money.
What about weighted keys? Are there any options?
Finding a module with weighted keys under $500 is tough. You're looking at compromises - either a lighter action or a less realistic feel. Most at this price range will be synth-action or semi-weighted.
Is USB audio a must-have?
It's incredibly convenient for direct recording into your DAW, but not strictly essential. If your interface has MIDI capabilities, you can still record the MIDI data and use the module's sounds separately.
How much polyphony do I really need?
32 voices is a good starting point, but if you're layering a lot of sounds or playing complex arrangements, 64 voices or more will give you more breathing room and prevent frustrating MIDI dropouts.
What's the deal with aftertouch?
Aftertouch is a luxury at this price. Don't expect it. It's a nice-to-have, but not a deal-breaker, and you can compensate with careful programming and expression pedal use.
