Fantastic! Updates Keep Coming

3/9/18 - Once again, another great update. Developer has made this even better. It hasn't left my iPad since it came out and was the first app I put on my latest iPad. (Previously, and still true) Perfect for my use with various folk musics. Valuable tool for copying poorly reproduced, and old (ancient) sheet music. Updates increase its value for me. (Previously, and still true) I have used this app for a while now. It has not left my iPad since I bought it when it first came out. Each version has been an improvement. I requested support using ornamentation and it happened. I like that I can transcribe with ease, and can immediately hear when a "fat finger" mistake has occurred. Plus midi! Received many compliments with the results. Highly recommended!

iWriteMusic is great!

I learned “computers” when DOS ruled the world. (Hang in there, I do have a point.) Back then only an IDIOT would go more than five minutes before hitting the “SAVE” command. SURE, “iWriteMusic” will crash periodically, but if you know that, and the program/app is as great as this “iWriteMusic” app? DEAL WITH IT!!!!! Adjust! I seriously doubt that you will find a better program anywhere that has this much power.

I do have one issue that currently frustrates me. I have almost 700 iWriteMusic files stored in the cloud, and - at the moment - I have NO way of importing them back into the iPad app. Everything was working FINÉ (pun intended) until the last couple iPad System “Upgrades”. THAT was when those programs could not be reloaded. Prior to that I would up and down load them - some of them - weekly.

More Than Notes On Paper!

What a help to have a portable, easy-to-use music writing platform that lets me hear just what I have written, with the instrumentation I want and with the parts (not the voices within a part) balanced for loudness throughout. For live performance, professional-looking separate part sheets are generated automatically.

Though verbal tempo marks are ignored, numerical tempo can be changed at every measure. So to sing a wedding solo with organ in a venue without an organ, I copied out the organ part, writing out the rubato explicitly, and handed my iPad to the disc jockey. No one knew!

Dynamics require two or more staves per part, unfortunately, and the staff for a seldom-used instrument has to extend throughout the score. Maybe fixing this in a nine-dollar app is too much to ask.
