Eso es muy fastidioso,sería bueno que lo mejoren.. ### 3/5 — Errores *2026-07-27, version 5.1.2* The updates are garbage: samples won't load, samples in previously created scenes don't work, and the sustain gets stuck—fix this urgently. ### 4/5 — Frickable *2026-07-12, version 5.1.1* This was a BIT better than a different AU soundfont player called “Fontstack”, however, the downside is that I CANNOT USE DRUMS ON ANY CHANNEL BUT 10, I NEED IT TO WORK ON ALL CHANNELS, WHY MAKE IT SO COMPLEX? FL STUDIO MOBILE DOES BETTER THAN THIS! I JUST WANT WHAT SOUNDFONT I CHOSE TO BE PLAYING! NOT COMPLETELY JAILBREAK THIS APP! PLEASE SIMPLY! I ALSO DO NOT WANT REVERB! ### 4/5 — Wavetables not working *2026-07-09, version 5.1.1* Everything works but the only thing that doesn’t is the wavetables every time I try to press library on the app freezes. This only happens on my iPad when I do it on my phone it works perfectly ### 2/5 — มีปัญหากับหน้า Wavetable *2026-06-29, version 5.1.0* หน้า wavetable ค้าง กดไปไหนก็ไม่ได้ แซมป์เสียงที่เอาไปลงหายหมด ลงใหม่ก็ไม่ได้ แก้ให้หน่อยครับ ### 2/5 — การเปลี่ยน Instrument *2026-04-06, version 5.0.6* Instrument ไม่เปลี่ยนตามหลังการอับเดต ### 4/5 — Amazing app, super fun to use and work with! *2026-03-30, version 5.0.6* My only issue is that MIDI will cut out for a split second sometimes, it’s usually just one audio track but sometimes it’s all of them. (Audio tracks that are bs-16i of course) Is there any way you could possibly fix this? It can be incredibly noticeable and a bit frustrating at times. ### 4/5 — It’s goated but *2026-03-26, version 5.0.6* It still crashes. I have no idea what keeps causing this and It’s pissing me off. It feels like the system wants me to blame this. Either that or it’s just my storage. It’s still really good but note to self: don’t use too much of it. ### 3/5 — Très bien mais… *2026-03-04, version 5.0.6* Bug très pénalisant et toujours pas réglé dans la version iPad. (Settings->Synthesizer->Part settings->Part #1 = Blocage total de l’App) ### 3/5 — broken *2026-02-23, version 5.0.6* i’ve used bismark bs-16i for about a year or two and ever since the implementation of the new version , neither the legacy nor the new version work properly as a plugin for garageband !! the soundfonts won’t load in either version and any project i have that has a soundfont crashes :( ### 4/5 — Don’t work no more [Fixed] *2026-02-22, version 5.0.6* Can’t load legacy edition no more in GarageBand. Nor can I here it in any of my songs that already had legacy edition tracks in it. Problem only happened this week. And it’s fixed the next day, thanks. ### 2/5 — help. *2026-02-21, version 5.0.5* Now, in garageband, it refuses to open the unit extension and crashes the app when I load any songs that had used this extention. ### 3/5 — Not Working Anymore *2026-02-20, version 5.0.5* I REALLY love using this plugin, as I consider it the best soundfont player for GarageBand. But, I can’t load songs that use it anymore. I’m not sure if it’s an issue with the legacy version of the app, or just with the plugin itself, but it’s pretty much unusable for me now, especially since I only really use the legacy version. ### 3/5 — Legacy version won’t load *2026-02-19, version 5.0.5* When I open a song in GarageBand that uses the legacy version, it crashes. ### 4/5 — can’t import midi song after last upgrade *2026-02-04* can’t import midi song after last upgrade **Developer response:** Version 5.0.6 resolved the issue. I apologize for any inconvenience this may have caused. ### 3/5 — Disappearing soundfonts *2026-01-02, version 5.0.2* I love this app and have used it happily for several years. However, with the latest update, each time I open the app , all my soundfonts except the installed general midi have disappeared and I have to reinstall them. Is it because I don’t use ICloud and install them from my files app? Please fix this and I’ll give you at least 4 stars… ### 3/5 — I love it, but… *2025-12-31* When I play back the MIDI when I use it on GarageBand, notes will sometimes not play. even when I export the songs, a random note will just not play ### 2/5 — Flawed overnight *2025-12-30, version 5.0.2* Its recent change to Version 5 has left it completely useless in garageband, as I cannot understand what the deal is with the standard version, and the legacy version which I used to use doesn't display any of the soundfonts that are still in the app. ### 3/5 — Lentitud *2025-12-30, version 5.0.2* Ahora se cierra al app al intentar guardar una escena ## Most critical reviews (10 lowest-rated) ### 1/5 — Help *2026-08-01, version 5.1.3* Hi, I’m asking for help because my app isn’t reading iCloud scenes. I don’t if I’m the only One having problem. Thanks. ### 1/5 — Freezing bug!!! *2026-07-13, version 5.1.1* Whenever i go into the menus for selecting soundfonts, they don’t even load, it just freezes and now i can’t use the app i paid for. Please if you would be so kind as to fix this? That would be amazing and mean the world to me. Still amazing app you’ve got here though, it has been SO HELPFUL! And to all those wanting to buy it, please do, it’s an amazing app. It’s totally worth the money aside from that freezing bug but I’m sure the developer will fix it soon. ### 1/5 — The legacy version of your app doesn’t work. *2026-02-21* So I use the legacy version of bs-16i for over half of all of my projects in GarageBand, and basically all of that is lost. I can’t open projects in GB that I’ve used bs-16i’s Legacy Version on without the app crashing, I can’t even use the Legacy Version anymore, I don’t know what’s going on. Please fix this, I am incredibly frustrated! **Developer response:** Version 5.0.6 resolved the issue. I apologize for any inconvenience this may have caused. ### 1/5 — 瞎搞 *2026-01-29* 升级了，原来做的工程不能用了。这老软件升级害人啊。还他妈死机。 **Developer response:** 5.0.6 版本已解决此问题。由此造成的不便，敬请谅解。 ### 1/5 — bad exporting ability’s and search ability *2026-01-23, version 5.0.4* it’s hard to export and find sounds i want a refund ### 1/5 — Have something wrong *2026-01-16, version 5.0.3* And now it can’t use sampler , it have something wrong. Please do it better. ### 1/5 — Problemi con sustain e polifonia *2026-01-02, version 5.0.2* Con aggiornamento sono aumentati i problemi e l’uso di risorse, sono già passato da 128 a 64 di polifonia ma fa dei click fastidiosi è non si può suonare, il problema si amplifica con il sudtain ### 1/5 — Falla la aplicación *2025-11-25, version 4.7.4* Se sierra la aplicación cuando guardo algún favorito ### 1/5 — Se apaga *2025-06-17, version 4.7.4* Se cierra solo la aplicación. ### 1/5 — Poor quality *2025-02-15, version 4.7.3* waste of money ## Most praised reviews (10 highest-rated) ### 5/5 — 外部音源として使用する際の不具合 *2026-03-17, version 5.0.6* このアプリで自分の中で革命が起きました。 しかしながら、不具合（？）が見つかったので報告させていただきます。 （環境:iOS17.4のGarageBand） 外部音源として使用する際にbs-16i(Legacy)を選択すれば設定中のInstrumentの音が鳴ります。 しかしbs-16iを選択した時、他のKeyboard領域からコピー&ペーストしたデータの場合に設定中のInstrumentの音が鳴らずピアノの音になるという現象が起きております。 改善方法があればご教示いただけますと幸いです。 ### 5/5 — More features by still the goat *2026-02-25, version 5.0.6* This is the best sf2 player, for little money, I really recommend this, coming from a user that uses this in band rigs, I kinda wish there more features, like if I play the note low velocity, that the filter cutoff be affected too, that way I can use less samples instead of having layers, saves more room, another thing I would like is that, an env thats also effected by cutoff, similar to how korg im1, has this VDF, and VDA EG under the “Easy” tab, if I play a note, I can make it where the note plays full volume, and like 2 seconds later it decays a little and stays like that the rest of the duration note is held. Also some organ effects like a “Wah” would be good if there isn’t one. If possible, adding these features would be very helpful when designing sounds. At the end, this is the best app, and definitely recommend to everyone ### 5/5 — Bs-16i legacy *2026-02-22* Thank you for fixing the crashing problem **Developer response:** I apologize for any inconvenience this may have caused. ### 5/5 — 更新后不能加载 *2025-12-29* 更新了audiobus加载不了 ### 5/5 — 使いたいのに使えない､､､(GarageBand) *2025-04-14, version 4.7.3* 毎回使うたびに重くクラッシュしていたけど何とか使えてましたがついに音がならなくなりました。 再起動、再インストール、容量の軽減化、などこっち出来る事は色々試したのですが読み込もうとすると(インストールされていません)と表示され読み込めません､､､ 対処してくれると嬉しいです ### 5/5 — Great *2024-12-02, version 4.7.3* This is a great alternative to Thumbjam. ### 5/5 — The best for literally anything!! *2024-07-04* I absolutely love this app and have been using it for about a year now. I use it in GarageBand for all my songs, and it’s saved the day multiple times. It allows you to take any sound font from the internet, and put it into your daw. Thank you for this amazing app! **Developer response:** Thanks! Please have fun. ### 5/5 — Estupendo teclado *2023-08-16, version 4.6.2* Sonidos decentes y funcionamiento y funcionalidad correctas ### 5/5 — 具体的な説明書が欲しいです *2023-08-09, version 4.6.2* いつも楽しく使わせていただいております！！ GarageBandにて呼び出して使わせていただいていますが、遅ればせながらこの度midファイルの読み込みがbs-16iで可能と知ってウキウキで活用させていただいています。 音楽ツールに明るくないため、手探りでやっています。しかし、やっぱりどこかで分からないところがあるとマニュアルが欲しいな…と思ってしまいます。 気が向いた時に、ツイッターでも、サイトでも、Facebookでも、このページでもいいので簡単な使い方を載せて欲しいです。ずっと待ってます！ ### 5/5 — Great app. *2023-03-27, version 4.6.1* Hi Devs, this app is really great for stage and home use! An Eq specially for the drums would make it perfect. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
