No setting button anywhere, please fix it cause the app sounds great. (and what about audiobus ?) thanks. ### 3/5 — Spiradisch kein Ton *2021-11-28, version 2.1.0* Ich bin mit der App im Großen und Ganzen zufrieden, benutze sie allerdings nur zum Üben zwischendurch. Muß ich nicht jedes Mal das Keyboard einschalten. Nur, was mich stört, ist, daß sporadisch kein Ton erklingt, muß das iphone resetten, damit es wieder funktioniert. ### 4/5 — Very good but *2020-06-22, version 2.1.0* Very good but would be better with AUV3 ### 2/5 — Utilisation avec une autre app *2020-01-29* Est il possible d’utiliser cet app simultanément avec une autre?Par exemple, l’app fonctionne bien, mais lorsque j’ouvre Musicnotes,par exemple, l’app Pocket Organ cesse de fonctionner. Y a t il un truc? ### 4/5 — Great sound but too less midi-function! *2018-06-02, version 2.1.0* The Sound of this app is really good. But for live playing I need more midi function for rotary on off etc. ### 3/5 — Nice but needs updating *2017-11-24* This app produce a nice organ sound but needs a major update with the following. - A better Leslie effect or a full Leslie bypass to use cubasis rotary effect. - Inter-app support - Audiobus support ### 3/5 — Not bad *2017-11-03* Sound is nothing special and feature set too simplistic. I would like to see this guy create a full featured app with more attention to the sound and flexibility and features. It has been a long time since last updates, which bothers me. Apps like music making ones should be updated fairly regularly to keep up with changes like new IOS versions and new audiobus. Its not interesting to buy an app like this, make it a part of your arsenal and then for it to be no good because of compatibility issues. And updates to functionality is nice, especially since that is what some excellent apps do regularly. ### 4/5 — Awesome Organ *2017-05-27* Great instrument; But I can't agree more with the other guy's comment...this app would have it nailed if only you could control the Leslie's speed via foot pedal. I solve this frustrating issue by switching the the app's brake to off, then open it in audiobus along with ToneStack 3 (Yonac). I then play it through 2 of ToneStack's most killer stompboxes: the 'Rotarybox' and the 'Scanner chorus/vibrato'. It makes for a super sweet combination. NOW... I do want caution those of you who use iRig keys PRO. I have had a weird problem with C3B3 repeating the same register/octave while move up and down the keyboard. It's only happened w/ this app on that controller (???). If I'm missing something, help me out; But I can't figure it out. I'm thinking its the app because when I switch to another app like Garageband I don't have this problem. I only use C3B3 with either my Carbon 49 or Axiom 61. Anyway I'm sure that's plenty to ponder- that's my 2 cents- BJMc Chicago- ### 4/5 — ICON *2016-12-11, version 2.1.0* Please, bring back the old clean Icon. ### 4/5 — ロータリーについて *2016-10-31* microKEY AIRでBluetooth接続して使ってます。 モジュレーションホイール操作でロータリー切り替えできると有難いです。 無理ならロータリー部分だけの拡大画面を作ってもらえれば、キーボードの横にiPhoneを置いて使うという方法もあります。 ### 3/5 — Background *2016-06-08, version 2.0.0* I need the app work even when I'm outside of the app. ### 3/5 — Kaydee *2016-05-31* Having tried Pocket Organ and 2 other products from same supplier, they all sound great, very authentic. Good job guys. But your can use a lot of improvement. Please, in the next updates, add support for Expression Pedal and other MIDI controllers like Rotary Speaker speed (Leslie slow/fast). I'm using those in gigs and cannot rely on touching the iPad in the right place at the right time to get the changes I'm looking for. ## Most critical reviews (10 lowest-rated) ### 1/5 — which scale ? *2026-02-28* could not do even one normal scale, two contiguous notes giving same sound. ### 1/5 — Don’t want it *2025-12-24* Don’t want it no more ### 1/5 — Not a good organ *2024-06-03* I need my money back ### 1/5 — Me cobraron mas dinero *2023-05-31, version 2.1.0* La aplicación dice que cuesta MXN$19.00 pesos mexicanos y al realizar el pago me cobraron MXN$299.00, quiero la devolución de mi dinero por favor. The app shows a price of MXN$19.00 Mexican Pesos, but, when making the payment, they charged me MXN$299.00 Mexican Pesos, I want the return of my money please. ### 1/5 — 残念… *2020-12-21* 良くなっていくのでしょう。 ### 1/5 — 音でまへん *2020-09-29* 金かえせ ### 1/5 — UIが悪い *2018-12-10* 何よりもUIが直感的ではなく何がどこにあり何ができるのかがわかりづらい。 今となっては数あるオルガン(の音が出る)アプリに比べてとりわけ音がいいわけでも使いやすいこともなく、もはや購入する理由はないと思われ。 他のアプリに比べ個性があるとすればキモダサくなったアイコンくらい。 ### 1/5 — 使えません *2017-03-02* 質感がありません。 レスリー、回ってません。 わずかな金額とはいえ、損した感大きいです。 Garage Band のおきまりオルガンの方がはるかにいい音だと思います。 メモリが勿体無いので削除しました。 リヴァーブのガッシャーーんができるので、それだけは重宝しました。 ### 1/5 — オーディオバスインプット使えない *2015-10-19* オーディオバスのインプット表示画面にすら出てきません、まったくオーディオバスで使えません 対処ねがいます。 ### 1/5 — Note duplication is problem *2015-10-13* This emulation sounds very much like a B3, however there are sometimes 3 duplicate notes on 3 adjacent keys. So you can't play this like a real keyboard. Too Bad ## Most praised reviews (10 highest-rated) ### 5/5 — Really nice B3 simulator *2021-04-22* I use this app with a MIDI keyboard, and it makes a lovely, easily transported setup for jamming with friends. The B3 sound is decent. I think the rotary speaker effect sounds way too fast on the fast setting. I wish this was user adjustable. I also wish I could dial back the vibrato/chorus effect. But this definitely beats hauling 400 lbs of Hammond and Leslie around. ### 5/5 — Need help *2021-03-17* I am having a very hard time loading the presets that a bought. Can anyone help. I’m missing something. For one the app doesn’t have a u1 or U2 bank only 1 to 6. And how do I Play or install the patch names like Jerusalem? yes I already purchased it. Yes this is flustrating. ### 5/5 — Unequaled tone *2020-04-06* I am putting together an original psychedelic rock album and searching for the Steppenwolf keyboard sound. I put this app through an EHX Lester K with the drive cranked on both and get an amazing sound! I hate dealing with the iRig stuff though so I bought a nord Electro 6D figuring the sound should be at least as good as this app for $2.5K - no dice. To say I’m bummed is an understatement. Even into the Lester K the nord doesn’t come close. I’m new to the nord so I’ll see if there is a solution but this app is an amazing recreation of a Hammond organ and dirt cheap! ### 5/5 — A must have Hammond Players *2019-01-14* This app is a must have for any Black Church Organist. Jazz keys player. ### 5/5 — Excellent *2018-04-12* Merci à Bruno Micheli pour l'info 🎹🎹👍 Cette application est géniale avec l'écran de l'iPad et assez conviviale 👍 Utilisateur de Hammond en réel, je trouve cette appli sympa 😉 ### 5/5 — キーアサインおかしくないか？ *2017-12-23* リアルな音色で、お気に入りの楽器アプリです。 上段キーのA4とA4♯とB4,A5とA5#とB5そしてD3♯とE3,D4#とE4などのキーが同じ音階に聴こえます。曲が弾けないのが残念でならない。バージョンアップは繰り返しているが、曲を引かない人が作っているのですかね。この問題はiPad版だけですか⁇ ### 5/5 — Great developer *2016-10-06* I mentioned to the developer that it would be great to be able to change the midi channels. Boom - done. (Haven't checked if sustain pedal controls Lezlie like w g-band organs, but hoping..) Now I can keep GarageBand off completely; as its omni-midi interferes with the other instruments while I use Audiobus. The least I could do was purchase a Joey D soul preset for $.99! ### 5/5 — Excellent *2016-04-21* Ne pas oublier d'ouvrir le clavier du bas et mettre le bouton sur normal sinon mi et fa ainsi que si et do sont identiques. Une fois ce machin réglé ça fonctionne parfaitement ### 5/5 — I'm amazed... *2016-03-10, version 1.7.2* It's unbelievable what you can do on an IPad Air 2 with apps like these, who needs a recording studio or producer breathing down your neck, recording studios are quickly becoming a thing of the past... Jeff Mercer Mentor Ohio ### 5/5 — Faszinierend !!!! Ein "Must-have" für Keyboarder... *2015-10-26, version 1.7.2* Es ist schlichtweg beeindruckend, wieviele Features die Entwickler in diese App hineingepackt haben: Ob (programmierbare) Drawbars, die Leslie-Funktion (inclusive Full-Stop), der Overdrive, Vibrato und Chorus, Decay, ein sauberer Hall. Selbst die Breite der Tasten ist einstellbar. Und dann lässt sich das Ganze sogar noch über MIDI ansteuern. Für mich ist „Pocket Organ“ definitiv eine meiner Lieblings-App’s. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
