From the iPhone version, you can't access the creation part of the app AT ALL. I checked manuals and everything, bogus ### 1/5 — 预制音色太少使用体验太差了，还不给退款，无语 *2024-06-12* 预制音色太少使用体验太差了，还不给退款，无语😓 ### 1/5 — Junk on iPhone 12 *2024-01-28* Impossible to read font and a ridiculous UI. It’s useless unless on an iPad. Another pea-brained developer. ### 5/5 — My AE-20 Loves The Q! *2023-10-13* Qithesizer is essential software for synth players. It is the only software designed for wind controllers that provides full access to multiple physical modeling and synthesis engines. Even the brilliant and mighty Respiro doesn’t invite you under the hood to create your own sounds from scratch. Many thanks to the team @RobKoo for your continued commitment to this great App. The Manual is now available in English via the in app or downloadable PFF version. Clutch. ### 5/5 — Awesome!!! *2023-10-01* One of my favorite apps!!! ### 4/5 — One Of The Best IOS Secrets What A Superb Synth! *2023-09-16* This beast is so responsive. A tweakers dream with tons of things to tweak. And it sounds so good. I have many ios synths. This one ranks in my top 5. Easiest synth of the year for me. I have reached out to the Dev about the moving around screen and sizing issues in AUM and they are working on a fix. Once that happens I will go back and give my review a deserving 5 stars. What an amazing surprize this synth turned out to be. Elektrik Diva ### 5/5 — Love this synth *2023-09-13* Love this for sound design. It’s unique in comparison to many of my other synths. So happy it became auv3 and also amazing that it is universal . I hope more presets will be added . Would love to hear more of the synths capabilities. ### 5/5 — Especially for wind synth *2023-08-14* All I can say is if you play a wind synth this is a must buy app. It sounds beautiful played on my ewi but I’m certain will play as beautiful on any device .I love the way you can easily map many controls at the same time to midi cc2 therefore have total control of what you are playing.it really is a great app and real easy to setup and use . To the developer can we some app just like this please **Developer response:** Thank you for your love and support for Qithesizer! ### 5/5 — Really fun to program *2023-08-01* Unique and I keep coming back to it, very fun for sound design ### 5/5 — 国产好软件 *2023-06-14* 相当不错。 **Developer response:** 感谢您的支持鼓励！ ## Frequently asked questions about Qithesizer ### What sound engines does Qithesizer use?
