## What is Bar Sequencer?

Available as a standalone app and an AUv3 plugin for iOS, iPadOS, and macOS, Bar Sequencer presents a unique fusion of metronome aesthetics and sequencer capabilities.

A Seamless Blend of Metronome and Sequencer.

Bar Sequencer marries the simplicity of a metronome with the versatility of a sequencer, creating an unparalleled music creation experience. This compact tool packs a punch by allowing you to effortlessly craft intricate sequences, including polyrhythms and polymeters, all within a minimalist interface.

Efficient and Innovative Design

Bar Sequencer isn't your typical step-sequencer or piano-roll tool. Instead, it employs a blend of proven concepts, combining several patterns in a way that's both innovative and intuitive. Despite its straightforward appearance, Bar Sequencer incorporates smart design choices to enable easy creation of even complex sequences.

Key Features

One Bar, Limitless Possibilities: The app focuses on displaying a single bar at a time, while allowing you to add an unlimited number of bars to your sequence. Each bar can have a distinct meter and beat division, opening doors to diverse rhythms.
Individual segments correspond to specific music notes or sounds. Adjusting segments' attributes is a breeze, thanks to the user-friendly interface.

Multi-Track Magic: Craft your compositions by adding tracks without constraints. Each track corresponds to a MIDI channel, driving various patches or instruments.

Global Tempo Control: While each track operates independently, the tempo remains consistent throughout the entire project. You can choose to sync with your host application or maintain an independent tempo.

Expansive Sound Library: The standalone version features a built-in library of essential sounds. In contrast, the AUv3 plugin serves as a MIDI processor, interacting seamlessly with a wide range of third-party instruments.

Continued Development and Ambitious Goals

Bar Sequencer's current version is just the beginning. The application's potential is poised to expand, with a roadmap featuring an array of ambitious features. These include humanization options, swing adjustments, MIDI file export, and much more.

Demo Version and Beyond

The demo version includes a 4-minute time limit. However, this timer resets upon each plugin reload or when selecting the full sound library in the standalone app settings. This allows you to explore and test the application's capabilities without restriction.

Whether you're a rhythm enthusiast or a seasoned composer, this application empowers you to create exceptional grooves and intricate sequences effortlessly.

*2025-05-21*

Hold down notes to change pitch.  Took me a while to figure this out.  Solid sequencing app, really requires the auv3 purchase as the internal samples are extremely basic

### 5/5 — Very good

*2024-06-27*

I love this app. Initially it was difficult to navigate, but now i have it down it had become very useful for me. I use jt to figure out how to deconstruct my drum parts.  It would have been nice to have a ability to move my creations from one device to another.
