BEST FREE SAMPLE LIBRARIES & SOFT SYNTHS - CURATED LIST OF REVIEWED & RECOMMENDED INSTRUMENTS (2024)

A Curated List of 100+ Best Free Sample Libraries, Plugins and Free Soft Synths (UPDATED JUNE 2024)

All libraries have been tested and abrief review is provided before each link.

Finding free sample libraries is easy these days. Finding really high quality sample libraries that sound good and play well is a lot more challenging. It commonly means sorting through a lot of -- I'll be kind -- less than great sample libraries.That's why I thought it would be helpful to the community to create a curated list of RECOMMENDED free sample libraries that play in a free sample players. Thislist onlyincludes libraries that I have used andfind worthy of recommendation. Many of these libraries, while very good to excellent, often aren't meticulously detailed and ingeniously scripted like better paid sample libraries. But that level of detail may not even matter for your purposes.

I invite others topost libraries that play in free sample players that they have used and can personally recommend.I'll update this list periodically and welcome suggestions for making it more convenient for people. I've also added free soft synths and invite others to add and discuss their favorites, likes and dislikes. Of course, my choices reflect my style, personal taste and the genres I play, so I hope we can get recommendations from others in order to represent a wide range of styles/genres. I mostly play rock, so if you play/produce other styles, we can especially use your input.

⭐=Highly recommended favorites.

SoundPaint Pluck & Hammer Grand Piano⭐⭐
I definitely would have bought this library if the folks at SoundPaint hadn't decided to give it away free. It's aKawaii Grand Piano recoded using guitar picks/plectrums and with a small metallic mini hammer. In SoundPaint's words, it's a "hybrid instrument that blends the characteristics of a harp, clavinet, guitar, lute, and harpsichord, with an added hammered dulcimer articulation." While you're there, I'd recommend picking up every freebie they have. SoundPaint is trying to win sample library users over and giving away a bunch of very high quality libraries for free. Even more, you can create your own libraries using their plugin, all for free.

The Real Piano
It took me a long time to decide if I wanted to include this piano library. Candidly, that's because I don't love the included presets. There's just something about the way it's EQ'ed that doesn't appeal to me.But I spent more time with the piano, tweaking the factory presets, creating my own presets, and using external EQ and I can now say that I might use this in a project where I'm looking for a very vintage sounding character piano. The sampled piano is a1903 Chickering grand piano. It is a Kontakt Player library, so you don't need to own the full version of Kontakt to use this library.

The Love Piano
This is a sampled grand piano with12 velocity layers "between the soft to moderately loud dynamic range (no loud or “fff” dynamics here!) and also included hammer sounds pedal sounds (both of which can be added/removed) to give it even more persona." It includes 18 reverb impulse responses.It sounds very nice. It's a free Kontakt Player library, so you don't need to own the paid (full) version of Kontakt to use it.

Steven Slate Drums 5.5 Free⭐⭐
A high quality, production ready rock drum kit. I think this is the best-sounding, deep sampled free acoustic drum plugin on the market. It includes a mixer and beats. It's a no-brainer to install and download, IMO.
FORMAT: DEVELOPER'S FREE PROPRIETARY PLAYER
https://stevenslatedrums.com/ssd5/#SSD5FREE

BFD Player⭐⭐
I think this is easily one of the best FREE acoustic drum plugins on the market, but I don't really love the presets and I'm not in love with the sound of the snare drum samples, so I'm only giving this two stars as a freebie. Personally, I deleted it from my hard drive shortly after going through the sounds and trying it in a production. The snare drum sounds thin and the heavy effects on most of the presets overwhelm the snare, it just gets lost in the mix. Still, these are 5GB of deep sampled drums with a built in mixer -- it's not extensive, but you can always route the outputs to use your own effects and mix the drums exactly as you like, and that's a pretty nice option for a free deep sampled acoustic drum kit; but it's also a bit of work. BFD Player also works with a large number of electronic drum kits and features more than 300 beats. I don't think it sounds as good or as professional as Steven Slate Drums, but it has enough going for it for a free drum plugin, that I'm still giving it my highest rating. Download it and judge for yourself.

Soft Drums⭐
This is a really nice, very usable traditional drum kit sample library. The drums are hit softly usingPromark Broomsticks, which gives a sound like when a rock drummer plays hard with brushes, giving the drums a thwack type sound! I think these would be very useful for indie or folk rock.
FORMAT: DECENT SAMPLER

Drum Gizmo
This entry is the exception to the rest of the list. I haven't used this library. It was recommended to me by a very talented KONTAKT developer who uses it. Based on his recommendation, I am adding it to the list. Drum Giznmo is a drum sample player system and a series of acoustic drum sample libraries. I am told that they are good to very quality. Note that the kits are unprocessed, so you'll need to apply your own effects, which is desirable for some and less desirable for others.

ELECTRIC PIANOS

Fracture Sounds: Blueprint Electric Keys⭐⭐
A beautiful, and well-sampled 1969 Rhodes Mark I Electric Piano library that's, unquestionably, good enough to be a paid library. It allows you to adjust the key noise. It doesn't have a bunch of presets, but it lets you choose between direct input and amped and has controls for stereo spread, reverb, chorus, and atmosphere. It's pretty obvious to see the developer's rationale for giving this away free. Once you use it, you'll be interested in their other libraries.

IK MODO Bass⭐⭐
This isn't a sample library, it's a modeled bass plugin, but it sounds very good, and is lightweight. It emulates a 1960's Fender Precision Bass. For free, I think this is highest quality choice for an electric bass guitar.

To put it mildly, this developer is pretty generous in what they give away free and they are a top quality sample developer. (One of their employees posts in this forum and has always been a class act, so really, nothing but respect for these guys).

Ample Bass P Lite⭐

ORGANS

SoundIron Aquae Organ
Aquae Organ is not a regular pipe organ sample library.

They then alterered the result using sound design techniques into something quite different and appealing in its own way.

This isn’t an Orange Tree Samples kind of detailed sample library. It’s very simple. But the ukulele has a lovely tone.

Ideal Bouzouki
Nice, simple. Worth installing. Multiple articulations. I love the plucked and fingered patch. If you’re not concerned about emulating the sampled instrument, the plucked and fingered patch has a harpsichord like quality about it.

Melodic Ping - Wine Glass Tool Kit
Nicely sampled wine glass hits.

Mixing Bowl⭐
It sounds cool. It’s bold. It’s fun. I like it.

Musical Stones
It’s basically a xylophone featuring stones. It’s nice but the samples are a bit noisy. Still I like the character of the tone of the instrument and the noise doesn’t put me off as I see it as a bit lofi.

Rob’s Andean Quena Flute
Think lofi Mellotron flute. I really like this.

Saraswati Vena
Simple, nice. I like it.

Shivering Keys
A really interesting lofi analog piano that almost sounds like it could work in a horror soundtrack, but I think it’s slightly too sweet for that.

Shivering Waves
A lofi pad that sounds a bit like Shivering Keys in a pad.

Signals
Sound effects that are perfect for sci-fi.

St Kathrin’s Bell
It sounds great, like a church bell. But there’s a lot of noise in the samples.

Synimer⭐
A very 80s/synthwave-type pad that sounds very good. I don’t know the song, but it sounds a lot like the synth pad from one of the songs in the 80s movie, “Breakfast Club.”

Timpani Hits
Nicely sampled, good sounding timpani hits.
