I GAVE THIS APP ONE STAR FOR ITS LACK OF BLUETOOTH STYLUS SUPPORT (and poor transcription accuracy.) IF THE DEVELOPER ADDS BLUETOOTH STYLUS SUPPORT (preferably Adonits APIs, and improves the handwriting recognition) I WOULD BE HAPPY TO CHANGE IT TO 5 STARS! Notate Me was exactly what I was looking for and it seemed perfect for anyone who knows notation and basic composition but wants to interact with their iPad like it is digital, playable staff paper complete with handwriting recognition. Compositions can be exported to MIDI or XML and opened in Logic Pro (or any DAW of your choosing) to use synths and other audio plugins (which is ideal since I cant play piano) or exported directly to PDF as sheet music. Things are often not what they seem and this app is no different, the user interface is designed for your fingers or capacitive stylus (which are simple, often rubber tipped, stylus that are very inaccurate for small intricate writing) Notate Me doesnt integrate any 3rd party Bluetooth stylus support (which would be fine if the handwriting recognition worked as described by the developer in the help file with capacitive stylus (of which I have two, but more on that below) however it only correctly translates input about 15% of the time on the first try, if you are slow and patient.) By not supporting bluetooth stylus Notate Mes palm rejection is nonexistent and it has a hard time even registering input when using either one of my 2 Bluetooth stylus (I have a Adobe Ink and the Adonit Jot Script both of which are supposed to work with or without their APIs.) As I dont own a iPad Pro (I own a iPad Air 2) I cant compare the differences in input using the Apple "Pencil." But, I can say that: INTEGRATING ADONIT BLUETOOTH APIS WOULD DRAMATICALLY IMPROVE THE ACCURACY OF INPUT, REDUCE ACCIDENTAL MARKS BY ADDING PALM REJECTION (which this app desperately needs) AND ADDING PRESSURE SENSITIVITY FOR ALL IPAD USERS (the majority of which do not own a pro) REGARDLESS OF IPAD MODEL With Bluetooth 4.0. If Notate Me would support bluetooth stylus there would be no need to upgrade to the much more expensive iPad Pro just for the privilege of accurate input ($599 for the 9.7inch, 32gb model plus $99 for the Apple Pencil totaling over $758 with tax or, $901 for the 128gb model plus Apple Pencil with tax which is outrageous for a souped up iPad with hardware stylus support.) I am a huge fan of Bluetooth Stylus and have see first hand how much the input clarity and accuracy (in apps like Noteshelf and Adobe Photoshop for the iPad) improved when the developers integrated Bluetooth Stylus Support. I wouldnt be surprised to see a similar improvement with this app. Despite these issues, it is still the best app interface I have used (for iOS) for people who prefer to compose using "paper" and want to hand write their music (when it works accurately, which is a rare treat) but with features that integrate with DAWs and PC digital audio production and composition software. Just know that: 1. There is a pretty steep learning curve to get Notate Me to recognize and input notes that are even close to what you intended and arranging them after writing can be a huge challenge. (PROTIP; CLEAN YOUR SCREEN THOROUGHLY!!!) 2. Capacitive Rubber Styluses like the Cosmonaut or the Adonit Jot Pro capacitive stylus (with the clear plastic disk for the tip) work best for non-iPad Pro users (better known as the majority of iPad users) but still plan on having to fight the app pretty frequently to write anything accurately.(PROTIP; pinch to zoom in as close as possible for "better" but still difficult input recognition.) 3. Inputting notes can range anywhere from fairly easy, to tedious, to frustrating, to rage inducing until you learn how to; a. properly utilize the interface elements, b. get it to actually recognize different written notes and rests within two attempts of drawing them, and, c. avoid unintentionally touching the display with your hands which can result in scrawls of lines being drawn or random tiny blue dots on the score (which is a direct result of not having palm rejection.) Hopefully these issues can and will be solved in the future, but for right now I could only give this 1 star.
