I have had several music notations apps on my iPhone that I have not been satisfied with. Thus those apps have been deleted. Based upon the workflow of the other apps, iWriteMusic wasn’t very intuitive. However, following a bit of exploration/experimentation I found the app to be the one for notation on iPhone that I like the best to date. The only negatives for me thus far is that the tracks don’t seem to respond well to dynamic markings. I would like to have more volume control between tracks. Also, one additional feature that I would like to see is the ability to export in xml format.

編曲などの譜面作りには、不可欠なアプリで、大愛用させていただいています。 が、特にピアノ譜を作る際に、 ・大譜表のヘ音記号からト音記号までひとつの(メロディ)ラインとして描けない。 ・アルペッジォがグリッサンド記号として使えず、複数の音がないと出せない。 ・テキストにイタリックを入れてくださったことには大変感謝しているのですが、両手が入り混じっているピアノの楽譜で、どことなく真ん中ら辺にfやpの強弱記号を入れられない。 ・和音の中の一音をメロディラインにして伴奏部分に当たる音符の旗の向きを変えたい など、特にピアノの譜面用に特化した機能を『ピアノパック』の様に買い切りで出していただけたらとても助かります。 あと、a tempo とか、simile とか…Ped.マークとか、よく使う音楽用語や記号の定形を自分で作成して取って置けると助かります。 デベロッパー様、ぜひよろしくお願いいたします。(要求ばかりで申し訳ないのですが、一番使い勝手が良くて、ずーっとこれで作譜させていただいているので…)

楽譜製作が、直感的に動かせるので大変重宝しています。一点だけ、楽譜のテンポを変える際に、テンポのところをタップするとアプリが落ちます。改良をよろしくお願いします。

App disappears (shuts down), the app does not fill the full screen making it hard to keep up with where you are. Hard to see- too small. I have it completely open. Just up graded.

買い切り版という安心感と捜査のしやすさは気に入っています。ですが肝心の印刷ができません。 いったん別の場所にPDFとして保存したり、メールで自分宛に送ってみてそれを印刷しようとしてもエラー、エラー、エラー、…スマホの小さな画面を凝視しながらではろくに弾けません。特にコンビニのマルチコピー機への印刷できるようご対応のほどよろしくお願いいたします。

クレッシェンドなどの装飾記号をつけようとするとアプリが強制終了して話にならない。有料で売っている以上早急に改善するべきである。 これじゃぁ作曲も何もできない詐欺アプリに他ならない。
