Simple music sketchbook tool


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 it is not recommended to use sequencism to produce complex songs or to play songs live on stage.

• Multitrack editor: MIDI instrument tracks, chord helper tracks
• Support for SF2* and AUv3 instruments (*lightweight SF2 files only)

Has potential but not intuitive

I’ve just downloaded this app. It appears to have a great deal of potential but it’s the least intuitive app I’ve ever come across. Thanks for taking the time to create this app but perhaps you can simplify it for us.
