ScalePlay is a generative music app capable of producing the most intricate ostinatos and sequences by applying complex scale patterns over user defined songforms and chord changes. It can be used in music production and is also a fantastic tool for music education. It includes scale references for hundreds of scales, nine virtual instruments and 128 instrument sounds. Its unique set of features allows the musician to visualize scale relations and to play along with generated patterns. Modern musicians often practice playing scales according to organizing principles like thirds. What is meant by that is to play a scale tone, then its third, then the second scale tone, the third on top of that one and so forth. The exercise would result in the scale tones 1, 3, 2, 4, 3, 5, etc. Not an easy feat at first, because before even getting started, one has to know the base scale. Playing patterns through different keys and scale types finally is a demanding task even for advanced musicians. ScalePlay constructs patterns like these and much more complicated ones by using two simple grids. Grids have been around in music apps for years, but they are based on half-tone steps and include all available notes of the spectrum. That leaves one difficulty on the table, namely that of correctly identifying the notes of a scale. These grids also don’t easily allow for patterning as in our scale in thirds. So a different solution is called for and ScalePlay provides just that and so much more. In the application songs are used as metaphor to organize different scale types into a harmonic context. They are constructed with chords which in turn determine what scale types are available at a given time. During playback the app then cycles through these virtual chords or as with TouchPlay allows to call them up at will. This architecture is very helpful for superimposing ScalePlay patterns over existing pieces and even practicing improvising over changes. For practicing ScalePlay shows a pattern's progression on the built-in instrument and also provides a music notation reference. One can slow things down to need and play along. With the pattern lock feature all patterns can be kept in the same general vicinity. So instead of raising all scale tones when a base chord moves from C to G for example, patterns stay in place. This allows guitarists to practice scale patterns over changes while remaining in the same position. ScalePlay is also a fabulous generative music app. That is because of the magic that happens when these self-repeating scale structures are put in motion. Fantastic music occurs. Since ScalePlay supports virtual MIDI and can be recorded into any iOS based DAW. It also features TouchPlay for advanced looping. With TouchPlay scale structures can be looped endlessly and out of order. The TouchPlay environment is superimposed over ScalePlay's main interface and allows live switching between different scale types with the tap of a finger in continuous or full pattern mode. Of course ScalePlay supports multi-app multitasking as well as split-view and split-screen to make this feature even more useful. Instruments • Banjo, Bass, Cello, Double Bass, Guitar, Mandolin, Piano, Viola, Violin Some other Features: • 211 scale types • Virtual MIDI • Advanced looping with TouchPlay • Full general MIDI instrument library

手元のパート譜を、タッチ操作で書き写していくアプリです。 ■ 指の上下だけで音高が決まる 画面右下の音高パッドを上下になぞると音高が決まり、指を離すと確定します。 書き込む場所は譜面のカーソルが示し、なぞっている間はそこに下書きの音符が出ます。 指を離す前に音を確かめられるので、迷ったらそのまま動かし直せます。 ■ 押さえたまま、もう一方の指で音価を変える 音高を決める指を置いたまま、別の指で音の長さ・付点・臨時記号を切り替えられます。 臨時記号はダブルタップで固定でき、続けて使うときに押し直す必要がありません。 書いたあとの音符も、カーソルを合わせて音価を押せば長さを変えられます。 ■ 移調楽器はパート譜どおりに書ける クラリネットやアルトサックスのような移調楽器を選ぶと、譜面はパート譜と同じ記譜で表示・入力できます。 保存されるデータと再生音は実音なので、あとで他のパートと合わせても音が食い違いません。 ■ 曲の途中で拍子・調号・テンポが変わっても書ける 小節を選んで小節設定を開けば、その小節から拍子・調号・テンポ・練習番号を変更できます。 小節の追加・削除も同じ画面から行えます。 ■ 連符は3連・5連・6連・7連 選んでいる音価がそのまま連符の占める長さになります。4分音符なら1拍3連、2分音符なら2拍3連。 枠を作ってから中身の音符を書き込みます。 ■ 書いた譜面はファイルとして持ち出せる 曲は端末内に譜面ファイル(.musil)として保存され、「ファイル」アプリからも見えます。 共有シートで他のアプリへ渡せます。同じ作者の「プログラマブルメトロノーム」に読み込めば、 書き写した譜面をそのままテンポの設計に使えます。 ■ 書きかけを失わない 編集中の内容は自動的に退避され、アプリを閉じても次の起動で続きから再開できます。 すべて端末内で動作し、ネットワーク通信は行いません。広告もアカウント登録もありません。
