## SoundFonts Description
This is a straightforward yet powerful app that acts as a polyphonic audio synthesizer with a virtually unlimited collection of sounds. Under the hood, It uses an AVAudioUnitSampler to generate the audio output when you touch one or more keys. The sounds that are available come from soundfont (SF2)  files, such as those available online for free (and of variable quality). 

The app also exists as an AUv3 plug-in (included) so you can use it in your favorite music generation application such as GarageBand, Logic, or AUM. It also includes two AUv3 effects units – reverb and delay - which you can use separately as well..

The app supports MIDI input -- just connect a MIDI keyboard/controller to your iOS device and you should be good to go! There is also support for MIDI over Bluetooth. You can also control some app settings using MIDI controls, including the active favorite preset and the audio effects.

To use, simply select a SoundFont name in the left list, then a patch name on the right and start playing. Some additional hints to get going:

• Add a SoundFont (SF2) file that you have downloaded onto your iCloud Drive. Press the "+" button and then locate the file to add. You can always change the display name of the SoundFont  by swiping right. And you can remove a SoundFont that you no longer want by swiping left on its name.

• Bring up reverb and delay effects by touching the wavy "signal" button.

• Swipe right on a patch name to make it a favorite. Favorited patches have a star next to their name. You can edit the name of the favorite by again swiping right and selecting the edit action. You can remove a favorite by swiping left and selecting the remove action.

• Touch the labels at either end of the black bar to change the range of the keyboard. You can go as low as "C0" and as high as "C9". You can also change the range by swiping left/right on the black bar. Note that this ability does not exist in the AUv3 extension -- use the native application keyboard controls to achieve the same results. You can also toggle the keyboard sliding feature by touching the small arrow between the note labels.

• Switch between the soundfont patches listing and the favorites view by double-tapping on the patch name in the black bar above the keyboard. You can also swipe left/right with two fingers in the patches and favorites views to switch to the other view.

• In the view of favorites, you can edit a favorite button by double-tapping on it. You can rearrange the favorite buttons with a tap-and-hold gesture.

Finally, you can check out the source code! Go to the Support URL to find out more.

## SoundFonts Reviews in United States

### ***** "Favorite plugin but issues after iOS 26"
I’ve been enjoying using this plugin for GarageBand ever since I bought it more than a year ago! However, after updating to iOS 26, I started having issues with the plugin not being able to load. I tried redownloading GarageBand and the Soundfonts app, but I still had the same problem with it crashing and being unable to load. I think this is an essential app that makes GarageBand even better, so I really hope this is fixed. Thank you!
-- EjayVil, 2025-09-25

### ***** "Excellent app, responsive and helpful developer"
I downloaded this app after my partner showed it to me and it blew my mind, I had no idea such a thing existed. 

Initially I had trouble integrating it with Garage Band on my iphone, emailed the developer and they got back to me within hours with a solution that completely solved the problem.

This is the order of steps I took that solved my personal problem (no sound coming through the audio unit in GB): closing Garage Band completely, uninstalling Soundfonts, restarting my phone, redownloading Soundfonts, opening Soundfonts and THEN opening Garage Band—problem solved. 

Incredible work, highly reccomend this app.

### ***** "Fantastic app! MPE support would be amazing."
(Please :)
-- Andy31457, 2025-05-15

### ***** "Crashing Issue"
This app is really nice, however on GarageBand IOS, it repeatedly crashes, and there’s nothing I can do about it.
-- Compudah, 2025-02-23

### ****- "Regarding version 2.30.8"
Although this works great on iPadOS, this app won't validate as an AU using Logic Pro on macOS. It used to work for a while… I'd love to be able to use it again on desktop.
-- Neumuzik, 2025-02-14

### ****- "Best plugin I’ve ever used, just one problem left"
The only problem is that the instruments convert to sine waves every single time the performance is optimized (which happens A LOT in GarageBand). If this problem was fixed, than it would definitely be a 5-star app!
-- HalloWeiner💀, 2024-12-31

### ***** "Still crashing"
Not sure what happened but even after the recent update it still crashes whether it’s auv3 or standalone. I’m on 2017ipad pro w/ the 16.7 software update.

EDIT:

Bro that was quick, I mentioned crashing issues yesterday and today the issue is resolved. Where is the tip jar?
-- AFTR | PARTY, 2024-12-22

### ****- "AMAZING IDEA! But doesn’t always work as intended"
Overall I’m glad I got it, because when it’s working it’s very easy to download and use soundfonts from a ton of games. It does completely tweak out and forget it exists sometimes though. When it does this, you have to either reload the extension or possibly re-add all of the fonts back. You can’t really share the music unless you screen record it or something similar, and upon opening there’s a good chance you need to reload a ton. I love this app, because I can’t find anything else designed like it, but in order for it to really be useable it can’t glitch out like this… 💔
-- flowersparkleflower, 2024-11-30

### *---- "Crashed from moment 1"
Never even got to try it. Won’t open. Won’t run. Can’t use at all. 7.99 gone.
-- bukbonzai, 2024-11-18

### *---- "Currently unusable"
I am an avid user of this app, as someone who is really used to garageband’s Ui being able to use SF2s is incredibly helpful. However I haven’t been able to use it for WEEKS because it keeps loop crashing on itself so hard GarageBand thinks it doesn’t even exist! If this issue was fixed it’d be a solid 3-4 star product but at the moment I can’t recommend this to anyone
-- cdebanana, 2024-11-13

### *---- "latest update is crashing the app"
haven’t been able to use this app in weeks because of the newest upgrade… every time i open the app it exits out within a second. please fix this!!! i need my projects back :’(
-- weona ryder, 2024-11-06

### ***-- "Convenient, but tedious."
It is incredible at providing new SoundFonts to GarageBand, but it crashes way too often. Sometimes, the app would forget about my added fonts, and replace it with sine waves, and I would have to manually change every single track back to its original sound. So, be prepared to do that again and again when you download the app.
-- CZealous, 2024-11-05

### *---- "Great but…"
I like this app, it can be useful for loading soundfonts and other things. Is what I would say if the latest update didn’t mess up the whole app. Now all the songs I made with it are useless! Please fix this… (I’m on garage band iPhone btw)
-- SilviaXJ, 2024-11-03

### ***** "App keeps crashing after latest update"
Every time is try to the open the app it just crashes
-- noobypants156, 2024-10-28

### *---- "Very choppy"
Sometimes GarageBand will crash and remove all soundfont packs  meaning a factory reset
-- lbopalisytic, 2024-07-06

### *---- "Annoying to deal with"
This app would be great if it didnt keep deleting my soundfonts at random times and replacing them with the default ones, which means i have to reassign EVERY SINGLE INSTRUMENT to whatever song im making, and this happens very frequently

I wouldn’t recommend this at all until the developers fix this bug
-- Mark Mothersbaugh, 2024-05-25

### ***-- "It keeps crashing and getting rid of packs"
Half of the time when I use to on GarageBand it crashes and I have to go through and put the instruments back to what I had them as, and other times it just chooses to get rid of my packs so I have to put all of them back in. It’s annoying.
-- Moss Nesmith, 2024-01-23

### ****- "Extremely useful, HUGE glitch"
Ever since I bought this app, it has been a permanent asset in my music-making hobbies, but there's a huge glitch that makes it very difficult for me to confidently use. 

The LMMS I use is GarageBand, and Soundfonts functions consistently within it without many issues, other than the occasional bug where all of my soundfonts seem to disappear, but that is easily fixed by rebooting GarageBand, though I do have to choose my soundfonts again, which can be a little annoying. That's not the main issue though, the real problem is exporting it from GarageBand into an audio file (in this instance, a WAV). 

When I was first using Soundfonts, the song would export perfectly. Around 3 or so songs in, though, it simply wouldn't export properly. Instead, it would export the song with all of the instruments nonfunctional, and, upon further inspection, made the instruments nonfunctional within GarageBand itself, requiring me to reboot the app, choose the soundfonts again, and try the export again. This, though, did not fix the problem, and doing the export again broke the song and broke every soundfont once more.

I have no clue what could possibly be causing this, but it's a pretty awful glitch, considering it makes sharing the songs I make with Soundfonts impossible to share with others. I really hope this can be fixed, since all things considered, this app has been extremely useful for getting better instruments in GarageBand.
-- mijetboi, 2024-01-17

### ***** "SoundFonts"
I love SoundFonts because it’s the best!
-- PicklesFan97, 2024-01-05

### ***** "Great app, but I have a problem"
First of all, the app is great! The sounds are great, the features, everything! I do have one problem though, any time I try to use it in GarageBand, it randomly just stops working. And when I try to make a new sound with SoundFonts, none of the actual sounds are there, and when I try to upload a sound, it tells me that the app quit and I need to reinstall it. Other than that, 10/10!
