Capturing Your Ideas, Recording Your Songs,

The microARRANGER is equipped with powerful tools to capture your musical performances; and with different modes optimized for different uses.

There are two ways to record using the sequencer.

Backing Sequencer

There are two ways to record using the backing sequencer. Realtime Recording captures everything in one pass, as you play. Each part you play, and each part the microARRANGER’s Style engine plays, will be captured on a separate sequencer track. This allows any part to be edited independently at a later time.
With Step Recording, the chords can be entered one at a time, and you can tell the sequencer how long to play each chord, specified in beats and measures. Additional parts, fills, variation changes and other musical information can all be entered in this way. This method is ideal for creating a step-by-step foundation for your song, without needing to rely on advanced keyboard skills.

Song Sequencer

This is a conventional one-track-at-a-time sequencer, like those found in a computer program or a workstation keyboard, with 16 tracks and a capacity of 56,000 notes. Using the Song Sequencer, you can layer additional melodic parts onto a song created using the backing sequencer. This is a convenient way to add the finishing touches required for full-fledged song production.

Sequence data created on the microARRANGER is also compatible with Standard MIDI Files, so you can import it into your DAW or software sequencer. In your PC you can perform further editing or add vocal tracks to bring your song data to its final stage of completion.

Compact and Complete

The microARRANGER features 61 Natural Touch mini-keys proportioned for comfortable playing. The stereo speaker system is conveniently contained inside the microARRANGER’s compact body. Lightweight and portable, the overall length is only 87 cm, and the microARRANGER weighs a mere 5 kg.
Just turn the power on, and start turning your ideas into reality immediately; there’s no need to connect any other equipment.

Whether you use it as a convenient musical notepad or as a full-fledged compositional tool, the microARRANGER is a powerful platform for your creativity in many ways.

Interactive Styles Inspire Your Creativity

The microARRANGER provides 304 Styles from such diverse musical genres as jazz, piano ballads, Latin, pop, and rock. Each one can assist you in producing pro-quality songs. Each Style includes intros, endings, fills, and breaks that can be used to accent a section or change the course of the song.

Four variation of each backing Style are provided; each offers a different level of instrumentation or activity, allowing the song to build and alternate between sections. These backing variations can be quickly switched simply by pressing a button on the panel. The microARRANGER’s sophisticated chord scanning function detects not only standard chords such as major and minor, but also complex ones such as 9th or 11th chords – as well as inversions – ensuring that the musical parts generated by the Style will correctly follow the most ambitious chord progressions. You are free to edit these styles, and store up to 48 of them in internal memory. New styles will also be available for free download at By adding your own favorite Styles allows you to “customize” your microARRANGER for even more enjoyment.

Changes, Styles, and Music

Just set the tempo, play a few chords, and the Style Play function will begin to create music. With each Style, the microARRANGER follows your chord changes, voice leading, and the tempo you set to create additional musical parts to enhance your song.This can be something basic like a drum and bass rhythm section, an extra guitar part, all the way up to a stompin’ R & B combo with a full horn section
The choice is always yours. You can develop your song by selecting a Style that’s appropriate for the melody you have in mind, or try selecting various styles and playing around to see what melodies your imagination will come up with. You can also try different Styles with the same melody, to see if a different arrangement may better serve your song. By allowing the microARRANGER to take charge of the accompaniment and arrangement, you’re free to concentrate on your songwriting without losing that initial flash of inspiration. It’s an easy way to complete a rough sketch of your entire song.
