課金するとめちゃくちゃ強くなる。

サウンドパックなどのプリセットに課金することもできるのですがパラメーターが限られているので各パラメーターをエディット出来るようになるモジュールに課金するのがベターです。
そうすることでLFOやEG、FXなど一般的なソフトシンセのようなアビリティになるのでおすすめ。
iPadで使えばより使いやすくなるので、私はLaunchkey mini mk3と併せてステージで使っています。
Ableton Liveとの親和性も高く、この機能でこの価格なら安いと思います。

但し、同一アカウントの複数デバイス間でのプロジェクトのやり取りが出来ず、私用で使っているiPhoneで作ったプロジェクトをショーで使っているiPadへコピー出来ないのが残念。
現状、全く同じ音色とMIDIデータを手打ちでコピーしています(とてもめんどい)
そこがもっと気軽にエクスポートできるようになればKorg gadgetなどにも引けをとらないアプリになるのではないかなと思いました。
(どちらも方向性も出音も違うので単純な比較は出来ませんが)

それと、ドラムモジュールについてはモジュールに課金してもエディット出来る項目等が少なく買うメリットをそこまで感じませんでした。
これならサウンドパックを買うかなという感じ。
セルフサンプルの読み込みが出来たら最高なんですが多分これはサウンドパックを売るという商売なのでそこは文句を言わず気に入ったものを買うようにしています。お布施の意味も込めて。

あとはピアノやエレピなどのPCMシンセのようなモジュールが追加されればもっとお金払うのになぁって思ってます！よろしくお願いします！

Generally, I'm satisfied

It was easy for me to use as a beginner because the features aren't complicated.

Some of the additional instruments are similar to existing instruments and I am reluctant to purchase them.However, if I find an instrument I like from listening, I will buy it.

If I had a request, I'd like to have the ability to connect bars that I've made and make them into one song.

It's a translation, so it may be strange English.

Sequencer’s grid interface needs some serious work

Edit: after getting a reply from the developer, I updated the rating to 5/5

This is probably my most favorite music app on iOS in terms of sound and design, but working with sequencer is _very_ frustrating. I am writing this review in hopes that these features would be fixed in future releases.

Right now I think the sequencer really needs:

* Chromatic mode. You can choose a chromatic keyboard, but you cannot choose a chromatic scale representation in the sequencer grid interface. So basically if you select a wrong key, any note outside this key that you recorded will be shown as a thin line on the grid, which you cannot move or edit. I feel like this is unnecessarily frustrating, and could be easily fixed by adding a chromatic mode to the list of keys.

* A better way to stretch notes. Right now this is very frustrating, I am trying to stretch a note on the grid by putting my finger and swiping on the screen without lifting my finger (as it is supposed to work), but instead it either moves the whole note, or deletes the note. I would say the note stretching gesture works only 3/10 times, even with Apple Pencil, which is _super_ annoying. Is there a way to add a “move/stretch” toggle button so that it wouldn’t confuse the gestures?

* Group select, or at least a “select all” button. I cannot seem to find a “select all” button, thus having to delete every note manually. Again, if you have a lot of notes, this is very annoying.

* A button or a toggle to turn on/off note expression for MIDI keyboard when recording. For instance, currently if I use a MIDI keyboard to record a pattern, the sequencer remembers the velocity of each keypress. However, there is no way to turn that off if I don’t want this feature (or a select button so that I could group change velocity for all notes) - is there any way to add more basic ways for controlling/recording the MIDI input?

Overall, I am a big fan of this app, but I feel like the frustrating sequencer interface really limits its possibilities. I hope the developers could address some of these issues in the next updates.

Hi, thanks for the feedback, it helps us improve the app for future releases.
A chromatic option can be found in the sequencer view by pressing on the grid icon in the top right.
Also you can select multiple notes by pressing and holding within the sequencer until a square animation pops up, and then dragging across the notes you want to change. You can then move, delete, and vary the length & velocity of multiple notes at once using this technique.
