Free SoundFonts - Free Quality SoundFonts (sf2) - bs-16i SoundFonts

This aim of this site is to provide high quality SoundFonts (virtual musical instruments in sf2 format) that can be played using a midi keyboard connected to a computer, tablet or smart phone. Emphasis has been placed on real or acoustic instruments particularly piano and other favourites for keyboard players (pads, strings, electric pianos, organs and orchestral) but some SoundFonts here also include high quality guitars, some synths and ethnic instruments. There is also a nice GM set for playing general midi files. The SoundFont format sf2 is widely supported by lots of programs/apps and devices.

About this Site:
This project began as a quest to find a really good software piano. Not even the expensive commercial versions were satisfying to my ears.  Most had velocity switching problems and unpleasant tones. I came across the University of Iowa Steinway piano samples which were great but there was room for improvement in the way they were presented.  My goal was to have a selection of piano and other instruments that were pleasant to play and to keep them available for free. Using SoundFont editing programs Polyphone and Viena I have done some editing to allow for expression to give a more enjoyable and realistic playing experience where timbre changes gradually with velocity where possible and without that annoying jump that is commonly found. This was applied to many of the other instruments as well.
Polyphone does an excellent job where necessary at auto looping and reducing sample sizes without compromising sound quality.
The SalamanderGrand (Yamaha C5) has by nature so many velocity samples that it already has a great expressive sound. I have normalised the samples and re-attenuated it to suit sf2 format and simplified it by leaving out some pedal noises and other non-critical sounds. Using Wavosaur I have removed the gaps at the front of the samples to greatly reduce latency.

Recommended Apps for iPhone/iPad:
SoundFonts can be played on just about any device but you do need a program that supports SoundFont sf2 files. With the greater availability of tablets and smart phones, the setup for playing them has now become a whole lot easier and a lot more portable.
One app I can recommend for playing these SoundFonts is bs-16i from bismark.  Large SoundFount files like Nice-Keys-* listed at the top of this page have been tested and run perfectly on iPad Air2 and iPhone 6s. I have not tested them on lower spec devices.
To load a downloaded SoundFont to bs-16i in Safari from OneDrive/GoogleDrive/Dropbox choose Open or alternatively use iTunes to Add the file in apps, documents and navigate to the file.
A great app for playing and basic editing of general midi files is Sweet Midi Player which includes a lyric viewer for midis with lyrics/chords. You can load one of the General Midi SountFonts above to greatly improve the sound quality.

Tips for Nice-Keys Soundfonts:
If you are using the bs-16i or similar app try changing the Rx. Channel for say the first 8 channels all to 1. You will then have 8 easily accessible sounds to play at the touch of the Solo/Mute button. You can then mix for instance piano and pads together. Alternatively you could leave the channels 1 to 16 and use channel select to choose your favorite sounds.  To play two sounds together just put them on the same channel. This is handy for pianos where you can add the level of resonance you prefer. When layering sounds with piano choose the non resonance piano versions (available in all the SoundFonts) to avoid lack of polyphony problems.

I hope you enjoy these SoundFonts.

More Information:

Nice-Keys-Extreme-V1.5  The biggest SoundFont set at 1gb or 1000mb (645mb dedicated to pianos) includes just about everything except Bass, Drums and General Midi. PC users should not have any problems or if running on iOS this set runs perfectly well on iPhone 6s or iPad Air 2. It is still possible to load this set within the bs-16i app and run Sweet Midi Player app using GM set one at the same time for midi backing if required. This set has everything described below plus the addition of guitars.
Nice-Keys-CompletePlus-JNv1.5  A large set with three different piano types plus all the nice instruments.  All in a package of 943mb.  Pianos have different brightness and resonance settings available and all the nice instruments from EPs, Pads, Organs, Strings, Orchestra and Synths are included.  A printable link to the list of available instruments is here  Nice-Keys-CompletePlus-Instrument List
Nice-Keys-Complete-JNv1.2  A solid all-round performance set as above of 749mb including Salamander and Upright Pianos but excludes the Steinway Pianos.
Nice-Keys-PlusSteinway-JNv2.0  Has all the main performance sounds with one type of piano the Steinways.  This set a bit smaller at 495mb.  A printable link to the list of available instruments is here Nice-Keys-PlusSteinways-Instrument List
Nice-Keys-B-Plus-JN1.4  Same as above except the Steinways are replaced with a the more basic 33mb SGM piano. File size is 328mb.
Nice-Keys-B-JNv1.5  Same as the one above except the extended Nice Instruments are not included. Total size is 148mb.  A nice set and perfect for smaller Ram devices.

Guitars-Universal-V1.5  Combines the 2 guitar fonts below into a single SoundFont at 150mb.  Instrument List Guitars
Acoustic Guitars   Has 84mb of quality Steel, 12 String and Nylon Guitars. Quality Steel Guitar Samples from Keith Smith (
Electric Guitars   Has 66mb of Electric Guitars ranging from Les Paul, Single Coil, Jazz, Distortion and Overdrive Guitars.

SGMv2.01-GuitsPlusBass-V1.3  Is a high quality 300mb Midi SoundFont.
Based on SGM-v2.01 ( with improved quality acoustic guitars (21mb) and basses (50mb) and also designed to run on apps such as Sweet Midi Player. This is a great GM SoundFont and the one I use on iPad/iPhone and PC.  On PC you can install a new GM SoundFont using Coolsoft VirtualMIDISynth.  1gb of ram is recommended.  You can comfortably run this GM Soundfont in Sweet Midi Player app as well as the largest performance Full Keys Set 1 in say bs-16i app at the same time on iPhone 6s/iPad Air 2.
SGMv2.01-JN-SMPv1.1  Same as above without the custom quality basses bringing the size down to 262mb.
SGMv2.01-SMP-Stein-JNv1.0   As above a General Midi SoundFont but includes also the high quality Steinway Piano.  Size is 441mb with 180mb dedicated to the piano alone. This version does not include the custom basses.

At 480mb in size with 230mb set aside for high quality Salamander Pianos plus also includes the high quality Acoustic Guitars.  The downside of using this GM set is that you may be more limited in what performance SoundFont you load at the same time depending on the Ram available on your device.  On iPhone 6s/Air 2 for instance you can load this GM Soundfont into say Sweet Midi Player app plus Set 3 of the Full Keys into say bs-16i but if you were to load Full Keys Set 1 or 2 (the largest performance sets) you may push your device past its Ram limitations and it wont load. (You can easily clear ram usage in bs-16i app by loading the default factory scene).
SGMv2.01-Sal-Guit-Bass-V1.0   As above plus the addition of quality basses.  If size is not an issue then this is the GM set without compromise at 519mb.

Salamander Grands   The Salamander Grand Piano is a large detailed piano by Alexander Holm with 15 velocity layers (16 originally) and long samples.
( ( Some versions on this site have been carefully edited down to 6 velocity layers and looped at the almost inaudible tail ends to reduce Ram usage but the quality is almost indistinguishable.  They are based on a nicely sampled Yamaha C5 Grand. Samples have been normalised, re-attenuated, latency reduced and modified for sf2. Three brightness levels are available and optional resonance.
Detailed_Salamanders-PlusSteinwayUprights-v1.0-   The most detailed versions of the Salamanders plus also includes the Steinways and Uprights for versatility in sounds at 999mb in size.
Sal-Stein-Uprights-UltraCompact-JNv1.5   My favourite piano set with all three pianos (Yamaha C5 Salamanders, Steinways and Uprights) available to play at various brightness levels plus optional resonance.  The pianos have been compacted a little and the Salamanders have 6 carefully selected full range velocity layers rather than 15 but the sound is not compromised.  All samples are still very long (just not needlessly long). These are already included in the Nice-Keys-CompletePlus and Nice-Keys-Extreme.
SalamanderPlusUprightPianos-JNv1.1   Two pianos without compromise.  A very detailed and large set at 1030mb in size due to 15 velocity layers for the Salamanders and long samples for both pianos. There are various brightness levels of the different Salamander Pianos to choose from plus nice Upright Pianos using a different sample set.  All come with optional resonance effects.
Salamander-Uprights-UltraCompact-JNv1.0  Same as above but more compact (452mb) by looping faint tail ends and reducing velocity layers on the Salamander Pianos from 15 to 6. There is almost no difference in sound to the above set!  These are included in Nice-Keys-Complete.
Nice-Steinways-JNv5.8   A beautiful long sampled 3 velocity layered Piano 376mb in size with 5 Presets - Classic, Studio, Medium, Bright and Honky-Tonk.
Samples were obtained from:
Creative commons license
Extra velocity filtering brings this up to a virtual 8 layered piano.
Nice-Steinways-Compact-JNv1.5  Sounds the same as above and has the same number of velocity layers but long tail ends trimmed and looped at almost inaudible sections.
SalamanderCompact-sf2mod-JNv3.0  Arguably the best free piano on the internet and better than many of the expensive ones as well. Modified for sf2 with three brightness levels, two velocity curves and optional resonance at 592mb in size.  This version has 15 velocity layers.
SalamanderUltraCompact-JNv1.1   A much smaller 237mb version of the above piano but sounds almost the same with full expressiveness over the velocity range.  You will be pleasantly surprised at the quality of this relatively small Ram piano. This version has 6 velocity layers.
Nice-Upright-Piano-sf2-JNv1.3  One of the best upright pianos with 6 velocity layers, lots of expression and a bit of grit and imperfection.
Nice-Upright-Piano-Compact-JNv1.3   The same as above but looped and uses much less Ram.  
Combined-Nice-Pianos-JNv1.4  Contains the Salamanders and Nice Steinways in one set at 962mb in size. This set has the full 15 layered Salamanders and very long samples for both pianos.
Steinway B-JNv2.0  Is a compact (33mb) piano with three presets. Based on SGM piano samples with a little more expression. Pretty good sounding for its size.

Rhodes EPs Plus-JN1.5  Is an extended 50mb version of the Rhodes EP, plus also includes a DX7, Clavinets, Wurlitzer, Electric Grand and Harpsichord.
These are already included in all the Nice-Keys-** SoundFonts.
Rhodes EP  Is a nice expressive 8 layer 12mb Electric Piano with the classic Rhodes sound including slow and fast tremolo settings.

Nice-Strings-PlusOrchestra-v1.4  If you are looking for strings, harp and orchestral this is the set for you at 421mb (with 242mb dedicated to the harp that has over 590 samples and up to 8 velocity layers!)

Gothic/Celtic Harp by Jason Sommerlad.

The All Around Violin has three velocity layers plus key-off effects and is public domain.

Ethan's Cello is by Ethan Winer (

Nice-Instruments-Extended-V1.3  All of the instruments below plus the best Acoustic and Electric Guitars, EPs and Organs.  This set plus a piano set (say Sal-Stein-Uprights-UltraCompact-JNv1.5) will cover just about everything. It is 382mb in size.
Nice-Instruments-JNv1.5  Is a set of 200mb containing various expressive instruments including Flute, Sax, Trumpet, Violin, Chamber Strings, Banjo, Mandolin, Bagpipes, Sitar and Moog Synth.  Sounds have been edited to place emphasis on dynamics and responsiveness to touch. These are already included in the main Full Keys sets.

PNS Drum Kit  This free acoustic drum set is courtesy of the proVitamin GM free demo set (  PinkNoise Studio on the web.

Nice-4-Bass-V1.5 This is an sf2 simplified version of three different basses - all with 4 velocity layers.  It includes the 1958 Otto Rubner double bass played and mapped by Drogomir Smolken, recorded by Ludwik Zamenhof. The samples are exceptional and some percussive effects have been mapped to some high notes. Royalty-free for all commercial and non-commercial use. Copyright 2016 Karoryfer Lecolds (Karoryfer Samples). The original Meatbass sfz version for Sforzando has round-robin sampling and includes arco as well as pizzicato presets.  (
The included Electric Finger Bass is an Ibanez Roadstar Electric Bass courtesy of and converted to sf2.
The Electric Picked Bass is also from turtlesounds and there are some nice effects in the upper range including finger slides and percussive sounds.

Customizing Your SoundFont
Suppose you like say the large Nice-Keys-Extreme SoundFont but you wish it was a bit smaller and didn't include certain sounds.  You can customize it with just a few mouse clicks by using the free SoundFont editing program Polyphone.   Its very simple to do.
Download the free Polyphone program from here:
or just click Polyphone to go to the site.
Open the SoundFont with Polyphone.
Click the arrow next to Presets.
Right Click on any presets you don't want.
Select Delete.
Go to Tools, Global, Remove Unused Elements, OK.
Save the New SoundFont (File, Save As, rename it if you wish).  That's all.
The reduction in size will depend upon which samples are being used/shared between the various presets.
You can also use Polyphone to combine SoundFonts. Simply open two SoundFonts, drag a preset from one to the Preset heading in the other. Close the SoundFont you don't want (main folder title, right-click, close) then save.

htpp:// creative commons licence and samples were sourced from University of Iowa.  Extra presets, tonal adjustments and extra velocity filtering layers have been added by myself.
The Salamander Grand made by Alexander Holm (details above) who sampled his Yamaha C5 Grand and is quite well known for having a great sound. Most sf2/sfz versions seem to be lacking the proper dynamics, have latency problems or have been oversimplified. This sf2 version has addressed these issues yet retains its essential character including optional resonance but removes other non-essential sounds such as pedal noises.
The acoustic steel guitar was made by Keith Smith ( who graciously allowed me to use it. Extra presets, velocity filtering and some other changes have been made.
SSO Strings (Sonatina Symphonic Orchestra) is a creative commons licensed library. For violin, chamber strings and flute I have taken several of the instrument samples and layered them together to allow for expressive playing over the velocity range. Flute SSO for example contains soft, hard and overblown samples from SSO. To create chamber strings I have used bass strings, cello, expressive violin and viola over certain ranges of the keyboard.
Other sounds are the pick of the best that are freely available on the net and have been edited mainly to give better dynamics, layered with other sounds or adapted to suit sf2 format.
Happy playing,
John Nebauer
