Polyphonic soundfont synth

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.

Very choppy

lbopalisytic on

Sometimes GarageBand will crash and remove all soundfont packs meaning a factory reset

Annoying to deal with

mrenderkid on

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

It keeps crashing and getting rid of packs

Moss Nesmith on

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.

Extremely useful, HUGE glitch

RealKlumsyKraft on

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.

I love SoundFonts because it’s the best!

Great app, but I have a problem

MercedesSandwich on

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!

Love it!

Soundfont review on

United States

Works great! Only complaint is the tracks can’t be bounced in place while using the AUv3 version in Logic Pro for iPad. The audio will be rendered to sine waves instead of the currently loaded sound. Would love to see this addressed in the next update so I can use the plug-in more effectively in my productions

great, but…

This app is great, but the sounds stopped working, and I pressed restore, but that didn’t work. Why is this happening?

I love the is app, but…

The app works great at playing soundfonts but I can’t get it to work on FL studio mobile.

Two Words: Its Perfect.

The Perfect Budget Soundfont library! Very compatible with different soundfont files. allows you to tune, rename, and modify soundfonts you have, and even comes with some free ones!! Only minor nitpick is that i cant move soundfonts into different categories, but other than that, its peak!
