Yamaha's Mobile Music Sequencer enables composers to combine a range of phrase patterns and create musical compositions intuitively, following the flow of composition, from phrases to sections and from sections to songs.
Wherever you are, you can now sketch the outline of a composition. In addition, you can use the ingredients to delicately craft songs on a Yamaha synthesizer, or in Steinberg Cubase.

First, try loading the demo song (a number of demo songs are provided). Tap on the settings icon in the top right of the screen, select [Digital Sympathy] from the Presets under the File tab, and press the Load button to read in the song.

Create a song right away as follows:

Step 1-Create phrases
You can choose from a rich selection of 382 preset phrases (the phrase is the smallest unit in the structure of a composition). Under Phrase in the View screen, tap on a cell in which no setting has been made, then tap on the Select button on the left. To listen to a preset phrase, tap on its name. It is also possible to use real-time recordings made using the keyboard within an application, or user phrases which have been created using piano roll input. Using the powerful Loop Remix function, it is possible to divide selected phrases at specified intervals and then order them randomly, automatically insert rolls or breaks, and thus rework them into new phrases.

Step 2-Create sections
Combine multiple phrases together to create a section. Phrases are arranged in a vertical block and playback is turned on and off using the Section button at the bottom of the screen. The phrases can be managed as a single unit.
By specifying codes for individual sections, you can easily create variations. Using the Create command you can also create a succession of new sections based on the phrase that is currently being played back, which allows production to proceed smoothly.

Step 3-Create Songs
Put together complete songs by pasting together sections. This is easily accomplished by touching the Section area and then just dragging and dropping sections into the data area. Naturally, you can also input sections by recording in real time or by using the piano roll screen.

Not an arranger app! Cool and fun close to professional apps but not one...

In the best comment that this app haz someone said “this is a powerful arranger” - No, its not. Its a powerful and easy to comprehend looping and mixing loops app bot not even close to an arranger. Just because loops can be arranged in groups and steps this app is not an arranger or else Apples Garage Band is an arranger, and all of the music making apps are arrangers. Yamaha, Korg, Casio, Ketron etc. all of them are calling an arranger keyboard the one that control “styles” with one finger in real time. A style has at least four instruments. So far i haven't found a smart phone app that can do that despite the fact that smartphones are in some cases more powerful then laptops now days.

There are so many midi styles that are cool and ready on internet that can spark the next idea and so many music making apps groups ignore having this option in a pocket versions. Like how hard it is to make an app to play and edit any midi style from all kind of old arranger keyboards in a smart phone that already is capable of rolling some extremely hight quality graphics?.. this is just sad because literally i am looking for this kind of app since the iPhone 4s came out.

Huge Potential if you invest the time

This is an absolutely excellent and powerful arranger app that is a secret weapon in my iPad music arsenal. Feature for feature, there are very few iPad apps (if any) that can compete with this programs long list of abilities. So why is it not more popular? While it is daunting as it goes pretty deep, I think the real obstacle of this program is a beyond terrible interface design, and a very limited and dated sound palette. With that said, the ability to export as MIDI, as well as a half a dozen other arranger formats, this app has mojo for those that look beneath its creepy pink surface.

Best music app by far in the app store.

I think this is an excellent app. I enjoy this app every time I use it. I have been making very good songs with it. I just hope that the app will work with the new iOS coming up this fall 2017. With all the new good features in the new iOS. I hope this app is compatible otherwise I would not install it. If I had to choose between new iOS and Yamaha music sequencer. I won't think twice. Clearly I will choose Yamaha.
