How to choose the best general synthesizers
Sound Quality
It's not just about 'good' tone. We're looking for character - that fat midrange honk, a usable low-end thump, or a sparkling high end that doesn't sound ice-picky. Does it cut through the mix, or get lost in the mud?
Polyphony
A synth with limited voices is a frustration waiting to happen. Four voices is workable for lead lines, but if you're layering pads or playing complex chords, you'll want more - ideally, 6 or more.
Modulation Options
LFOs, envelopes, and modulation matrixes are what breathe life into a synth. A few basic knobs are fine, but the more you can tweak and mangle, the more sounds you can create.
Build Quality & Action
Let's be real, this price range means compromises. We're assessing keybed action (is it velocity-sensitive?), knob smoothness, and overall construction - because a flimsy synth won't survive a gigging lifestyle.
Connectivity
MIDI in/out is essential, but USB MIDI is a huge bonus for modern recording setups. Audio outputs (stereo, mono, headphone) are also critical for routing and flexibility.
Buying guide
So, you want synth sounds without breaking the bank? It's totally doable. Forget those sterile, cookie-cutter sounds - we're talking about getting character, grit, and enough sonic flexibility to cover basslines, pads, leads, and quirky sound design, all for under $500. Let's cut through the marketing and find you something that'll actually inspire you.
At this price point, you're trading. You're likely sacrificing premium keybed action, deep modulation, or pristine audio conversion. Don't expect boutique-level build quality - these are workhorse instruments.
Prioritize the sound engine and modulation options; a decent sound is more valuable than a fancy case.

Questions
Can I really get a decent synth for under $500?
Absolutely. The used market is your friend here. You'll find a lot of capable synths that were once higher-end but are now accessible at budget prices.
What about software synths? Are they better value?
Software is great, but it's a different workflow. A hardware synth's tactile interface and immediate response can be inspiring in a way a computer screen can't. Plus, no latency worries.
What's the deal with 'virtual analog' synths?
It's a marketing term, but often means a digital synth emulating classic analog circuitry. Some are fantastic, others are just okay - listen carefully to demos before you buy.
I saw a synth with a ton of knobs - is that automatically better?
Not necessarily. Knobs without meaningful control are just clutter. Focus on the types of modulation available, not just the quantity.
What should I do if the keybed feels cheap?
A cheap keybed is a compromise. Try to find a synth with semi-weighted keys if possible. Alternatively, consider pairing the synth with a separate MIDI keyboard for better action.
