Not only are the keys sticking, but when you hit a chord it hits some weird notes. Some of the Chinese instruments are spot on. I will give this 4 out of 5, probably a 2 if the recordings I need required using string assembly 2. Please investigate and fix so I can come back and rate it a 5. I uninstalled and reinstalled and still have the problem. **Developer response:** Thank you for the feedback, we will trace it. ### 5/5 — 很好 提个建议 *2020-03-25, version 2.0.2* 希望可以实现这样的功能 可以直接从ipad导入播放 Midi格式音乐 并且可以在多个音轨不同的乐器播放就完美了 ### 5/5 — 专业版能不能打折？ *2020-03-12* 因为不会但是又想弄了玩 ### 5/5 — 这个软件就应该五星 *2020-03-06* 对于我这种电脑白痴来说，ipad成了我编写音乐的主要工具了，然鹅音源实在是太少了，我终于找到了了类似kontakt的软件……加油！应该给五星 **Developer response:** 期待你更多的使用反馈 ### 4/5 — 内录 *2020-02-22* 不得不过来评论 那是因为这款软件体现了它的价值 说实话库乐队都没法让我去内录 用otg感觉没啥意义 过多的不说这个是我最认可的地方 刚下下来目前功能尚待开发 不过对我来说这一个可能就够了 另外注意下软件的流畅度 最后 希望研发人员一切都是为了音乐出发的角度去开发定位 ㊗️一切顺利 **Developer response:** 感谢您的支持 ### 5/5 — Great start *2020-01-21* Allow for octave change and dual keyboard option on play screen. Leave list of samples where they are when choice is made instead of having to start from the top of the list. Some of the samples are familiar and have the loop popping especially in the string ensembles. Aux3 or at least an effects array. When you build a monster you have to feed it. Lol **Developer response:** Yes, these are on the TODO list. Enjoy! ### 5/5 — Update *2019-11-19* Something happened. I get an update notice and the app stays in update mode. I can hit update but it will spin a bit and go back to update. It’s happening to my other apps too. Any ideas? **Developer response:** First thank you for download JamKoo. The problem you mentioned seems an issue from the App Store app, but we will trace and keep an eye on it. Let us know if you still have the problem after you try another time. contact@robkoo.com ## Most critical reviews (10 lowest-rated) ### 1/5 — Cyber spy or something *2022-10-07* This is not even the same app that was on my phone in the beginning of 2022. What is this thing. Initially it was a friendly keyboard and now is a mess of crap. It is wanting a login now to collect your information. BEWARE!!! ### 2/5 — R1 Robkoo ewi users *2023-11-14* The app is useful if you have an R1 as it let’s you change parameters on the R1 via the app however the interface really needs sorting out. This app seems to be designed primarily to sell a subscription, with almost 100% of the descriptions only in a Chinese script, a language I cannot read. Please either update the user interface to reflect the language of the user throughout or provide a standalone app just for managing the R1 updates and parameters. The R1 is a global product, the app needs to match. ### 3/5 — 語言 *2024-09-03, version 4.3.10* 找不到更改中文的地方 ### 3/5 — ？ *2024-09-03, version 4.3.10* 不知怎麼改中文 ### 3/5 — 软键盘有时失灵 *2020-10-03* 软键盘要点好几次才会发出声音，可能主打连接乐器演奏？音色也没有想象中的多😂不过创意很好，希望用起来能像库乐队一样顺畅，加油！ ### 3/5 — 没法下载 *2020-07-09* 我买了笛子的安装包但是总是下载失败怎么回事 **Developer response:** 添加我们微信为您解决 ### 3/5 — Won't open?? *2020-07-03* Crashes immediately, every time...Help? **Developer response:** Please delete the app and reinstall then restore purchase, this will help. ### 3/5 — 反馈 *2020-05-15* 屏幕边缘的键按不下去，不灵敏。还有这个软件和库音乐有什么区别呢？（我只是觉得比库音乐简洁，不知道有没有其他区别） **Developer response:** 感谢您反馈，部分机型的兼容性我们会持续优化。您可以尝试一下连接电钢琴，MIDI键盘等等，效果非常好哦👍 ### 4/5 — JamKoo *2024-11-18* 4 Stars ### 4/5 — 好 *2021-09-22* 社区里有很多老伙计，可以学到不少优秀的作品 **Developer response:** 感谢大家的陪伴 ## Most praised reviews (10 highest-rated) ### 5/5 — 初次使用 *2025-07-02* 好，乐器人的必备！ ### 5/5 — 功能齐全曲谱丰富 *2024-06-03* 功能齐全完善曲谱丰富多彩，就是动态谱的更新有点慢哈 ### 5/5 — 我的收藏为什么总是丢 *2024-03-31* 我的收藏为什么总是丢?莫名其妙的消失。那些伴奏的乐谱是不是可以都显示出来，不要总用0来占位。倚音标住小得让人看不见，换行时有时会有音符跑到屏幕外面，有时会有几个叠在一起。 **Developer response:** 我们已经加强优化了收藏曲目的模块，您丢失的曲目应该已经回来了。 ### 5/5 — 很不错👍👍👍 *2023-10-08* 但有一处盼改进：即进入“我的收藏”并下载的曲子，过一段时间后，总是有一些曲子会不见了，又得重新下载喜欢的曲子。用自乐班两年了，一直存在这个问题？ ### 5/5 — KGED *2022-09-12* Jam 2. 4. 6. 8. 10 ### 5/5 — 评价一下空音吧 *2021-10-21* 其实空音本身是一个悲剧，作为中国本土第一个走上台面的音源商，却被盗版整的半死不活，甚至于多年来都没有新的产品。但是做为一个音源商，我不希望他消失于历史中，今天看到这款软件，我是打自心里的高兴，因为这证明他还在我们看不见的地方努力生存、奋斗着。希望可以看到在这之后，空音能够站起来。对世界说：＂我回来了＂。 **Developer response:** 感谢您对国产音源的关注，我们和空音一直保持着良好合作。国产品牌会越来越好的！ ### 5/5 — Great app *2021-04-03, version 3.0.5* I use it with an EWI USB via a Yamaha UD-BT01 for Bluetooth on an iPhone XS. Good set of included sounds. Loads your own sound fonts. I had an issue that the developer responded to quickly - working very well. ### 5/5 — 弹弦乐器如果能有颤抖音色效果就更好了 *2021-01-05* 比较全的，不过还是比较希望在上个古典吉他的音色，然后比较希望这些个拨弦乐器，他们可以有颤抖的那种音色 **Developer response:** 我们已经收到您的反馈啦 加油💪ing ### 5/5 — 蓝牙 *2021-01-01* 蓝牙连接电吹管特别容易连接不上 ### 5/5 — 新版有BUG，请速修正 *2020-06-18* 新音色中二胡的两种是一样的，长音那个不是长音呀，最关键的是录音的文件格式的修改，MP3自然好，可是录完后要缓存好久，就是卡住很久才能保存下来，原来的M4a格式已经很好了，关键是保存快，还有每种音色音量和伴奏音量调好的比例，每次重进后都会变，音量是已经再进后变小，而伴奏是一重新载入后就声音大的要命。新音色包都买了，可是除了笛子比较满意，其它的真的没觉得有性价比，原来最早的灵魂尺八，没实话还真的是有灵魂的音色，说这么多，是一直在用这款软件来录制，希望越来越好用，望制作者采纳建议，辛苦了。谢谢😊👍🏼 **Developer response:** 感谢您的详尽反馈，我们已收到，近期版本优化更新 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
