Sequencism is an easy-to-use sketchbook app with essential tools for creating music including full support for AUv3 plugins.

Sequencism is a music sketchbook app that allows the creation of short and simple pieces of music. Rodrigo Roman released today version 1.0.50 that brings initial support or AU MIDI in AUv3 effects, support for Solfege notation, and some minor bugfixes.

Already in an early version, the developer added full support for AUv3 instrument and effect plugins. Beside this, it comes with Audiobus 3 and Ableton Link support.


sequencism is a music sketchbook tool that allows the creation of short and simple pieces of music. It is designed to provide a traditional user interface of track and piano roll editors, while taking advantage of the touch-screen capabilities of the iPad. It also includes other helper tools, such as chord helper tracks.

Note that the main goal of this app is to work as a sketchbook, thus I do not recommend sequencism for musicians that want to fully produce a complex song using only this app, or want to play songs live on stage.
