Nothing in the settings seems to fix this **Developer response:** Pen2Bow is a MIDI controller, it produces no sound on its own. This is clearly stated in the description and in my youtube videos. Please be so kind as to remove your 1* review. If there is something you want to add please leave a comment on one of my youtube videos (audio motion instruments). ### 1/5 — Not working with ipad pro *2020-05-18* Unfortunately its not working on the new ipad pro **Developer response:** Can you please get in touch with me on the Audio Motion Instruments Youtube channel and write a comment to one of my videos explaining what exactly does not work? And please be so kind as to remove your one star review, this is not fair. ### 1/5 — Was really excited to buy this but... *2019-12-10* It’s dead in the water...i have just about every music making app on here and invest on a lot of sound packs...however, this doesn’t seem to work with any of them. The onboard keyboard works with the other apps but using the pen only produces the light streaks but no sounds. I checked the midi data with midi wrench and there doesn’t seem to be any coming from the app...is it possible to have this fixed or to get a refund? **Developer response:** To me this sounds like a midi configuration issue. can you contact me on VI CONTROL (username Audio Motion) so we can troubleshoot? alternatively you can write a comment on youtube (channel: audio motion instruments). ### 1/5 — No functionality on iPad Pro 12.9 2017 model *2018-04-10* Have tried several different midi synths and none will produce a sound from using several different (Animoog, Volt, Vogel CMI, etc.) iOS synth apps using specific & network session outputs - inputs but still no sound at all. Same issue wIth previous release as well. **Developer response:** Dear BK Holiday. I replied to your comment on discchord (http://discchord.com/appnews/2018/04/23/pen2bow-update). We could try to troubleshoot there. Best regards ### 4/5 — Cool for sound design too! *2020-12-30, version 1.1.2* Why not to add X and Y coordinates as CC sources and the possibility to send a note on (a single pre-selected midi note) when the pen touch the surface (and note off when leave)? ### 4/5 — Needs better documentation *2018-04-03, version 1.0* Start the sound app first. Then launch pen2bow ### 5/5 — Logic Pro *2023-11-21, version 1.1.2* Bonjour , je viens d’acheter pen2bow mais il n’est pas détecter dans Logic Pro comme contrôleur . Comment faire ? Merci pour votre aide ### 5/5 — Must-have for SWAM strings! *2023-07-04* I've been using Pen2Bow daily for the past few weeks and have been really pleased with the level of expression and sensitivity this has enabled in my playing of the various SWAM string instruments. The use of back and forth motions with the apple closely simulates the experience of using a real bow, and the developer's unique implementation of circular motion enables a very smooth legato and eliminates the need to continually worry about getting to the end of the bow. This app really makes all the difference for anyone wishing to get the most realistic sounds from the SWAM string instruments. Highly recommended! ### 5/5 — Excellent controller for SWAM *2021-02-22* This took me a bit to get installed and there is a daily setup, like opening audio devices and selecting “enable”, but if you already have an ipad with a pencil, this a an awesome controller for dirt cheap... well worth taking the time to get it connected. READ THE INSTRUCTIONS. ALL OF THEM! I have the SWAM strings and can do a lot more with simple hand gestures than with the mod wheel. Good job! ### 5/5 — Wonderful App, very helpful for bowed stringe, and cc modulation by IPad *2020-10-25, version 1.1.2* i give 5 stars to this because is deserves. I use it with Swam instruments, that are physical modeling instruments and completely improve the playability of the instruments,chancing the bow direction simply with the movement of the pencil or adding vibrato or bow pressure in real time is awesome. Dimos is also very kind and patient,he helped me to find the cause of an issue that i had in Logic prox. Thanks Dimos.... keep improve it !!!!!! ## Most praised reviews (4 highest-rated) ### 5/5 — Le partenaire des instruments AudioModeling *2020-03-29, version 1.1.1* incroyable avec la contrebasse modélisée par AudioModeling. ### 5/5 — Superb MIDI Controller. *2019-03-27, version 1.1.1* Great addition to any iOS musicians toolbox. Watch YouTube demonstrations for a taste of what it can do. Note to developer: Please, please, make MIDI CC assignments user definable. I want to control CC#2 in particular but many others would be useful. I know I could use a utility to reassign the value mid stream, but with such a simple procedure I shouldn’t need to. The program is a great tool, but not just for string players! ### 5/5 — One of a kind! *2019-01-28* This app is really well made. It is stable, easy to use and visually pleasing to the eye. I use this for controlling different synth apps using AUM and Audiobus. I really appreciate what it adds for creative expression to Moog’s Animoog and Model D apps. One thing I would love to see is the ability for the keyboard to be set to various scales so that you could really focus on the sound manipulation and still always hit the right notes! Thanks for making this app and continuing to support it. ### 5/5 — Thanks for this *2018-04-25* Love the update, especially the built-in keyboard and settings page. Thanks so much for doing this. It was an app we didn’t know we needed, until you came up with it. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
