This product is a software synthesizer that supports Audio Units Extension (AUv3). Music software that supports the AUv3 host function, such as GarageBand or Logic Pro for iPad, is required to use this product. DOTEC-AUDIO DeeACID allows anyone to easily enjoy acid bass lines. In addition to a wide variety of sound creation, the level adjustment for overdrive has been auto-adjusted, allowing you to twist the knobs to your heart's content. The UI is specially designed for use with a DAW, and MIDI controller assignments can be made quickly and easily. It also features a variety of visual effects to enhance your enjoyment, so you will lose track of time and become absorbed in the fun! In addition, the phrase generator can generate an unlimited number of phrases according to key, and can also be synchronized with the rhythm track for real-time play! The generated phrases can be saved as MIDI files, so they can be loaded from a DAW and used. By connecting an external MIDI controller and pressing the “Learn” button located below each parameter, you can assign the parameter to the slider of your choice, allowing you to change the tone more intuitively! From version 1.5.0, the DJ Deck mode allows standalone play, and from version 2.0.0, the Ableton Link mode has been added. Now, DeeACID is not just a plugin—it can also be enjoyed as a fully standalone acid bass app! Furthermore, version 2.5.0 introduces brand-new filters and a supercharged phrase generator! From version 2.6.0, improved the oscillators so both Type I and Type II now deliver a thicker sound! ## Key features - Acid bass line creation - Intuitive MIDI controller assignments - Phrase generator with rhythm sync - DJ Deck mode for standalone play - Ableton Link support - Visual effects for enhanced experience ## Recent user reviews (10 of 12) All indexed reviews: https://appshunter.io/ios/app/dotec-audio-deeacid/id6737628611/reviews.md ### 5/5 — 面白い *2025-08-31* PC版も持っていますが、この機会にiPhone版も購入。リサイズ対応とありましたが、どうやってするのか分からず。iPhone16Proで画面からはみ出てしまい、ボタンが押せなかったりします。分かりやすく説明あればなぁ？ でも遊べるし音楽制作に活かせますね。 通勤時にも遊べて良いです。 ### 4/5 — Sounds like rebirth *2025-08-29* This is an acid machine. Good sound, fun graphics and auv3 works well as does standalone! Cheers ### 3/5 — MIDIマッピングについて *2025-06-04* Elektron機材からマッピングが上手く保存されません。 具体的にはSEND CTRL #76はマッピングせずに、#77にOUTPUTをマッピングして保存して再起動すると#76はTUNINGが動くようになり、#77はDETUNEのみが動くようになります。 ### 2/5 — Pretty good. *2025-04-13, version 2.0.4* I’m having fun with it. But For the price you’re charging, it should have some modulation or an lfo, it doesn’t feel like a finished product. It should be £1.99 until it has those features. ### 5/5 — Aciiieed! *2025-03-15* That one star rating is unfair! The issue has nothing to do with the app itself. Contact the dev and clarify your issue. I never looked at the manual. The app is pretty straightforward and is a nice extra texture vs my other “acid apps”! BTW the guide is accessed in the standalone and there is a close button at the bottom of the screen. If you’re an acid junky, then it’s an approach that’s different from others and IMHO worth getting. If acid is not really your thing, you may already have what you need. I dropped it in NS2, drew in some automations and got some fun stuff going in minutes. YMMV **Developer response:** Thank you so much! NanoStudio 2 is also a great AUv3 host app, so please use it together! 2025/1/24 Thank you very much again! We will continue to upgrade and evolve the app to make it even more user-friendly and fun to use, so please continue to enjoy it! ### 1/5 — （2025年2月現在）スタート・ストップがホストシーケンサーの動きに同期しない *2025-02-20* タイトル通りです。テンポのみ合っていますが、スタート・ストップはホストシーケンサーの動作には関係なく、本アプリ側のRUN/STOPボタンを押さないと動きません。ちなみにGaragebandに読み込ませるとテンポすら合っていません。PCを含め数あるTB-303プラグインの中でも、ホストシーケンサーの動きに同期しないのはこのアプリだけでしょう。 なぜか画面中央のアニメーションだけはしっかり同期しているので、同期方法がわからないわけではないと思います。そろそろ改善を望みます。 ### 5/5 — Aciiieed! *2025-01-23* That one star rating is unfair!

DeeACID is a plug-in synthesizer sound source called AUv3, so you need another application to host it. If it is free, for example, you can use DeeACID by importing it from GarageBand as an External sound source, so please try it. (2025/1/24) We have added stand-alone functionality for DJs, so please update and activate it. The application can now be played stand-alone. ### 5/5 — If you like Acid then step inside. *2024-12-05, version 1.0* You will never get back out. Wasn’t sure about it when I first seen it. However after buying it I am quite delighted. It sounds fantastic and it’s great fun. The controls on it are extremely tweakable and there are more available than on your standard 303 set up. Have some drums, effects, vocal samples etc along with it and you won’t believe what you come up with. Nor will you believe how long you have been at it. ## Frequently asked questions about DOTEC ### What is DeeACID? DeeACID is a software synthesizer that specializes in creating acid bass lines.
