Percussa micro super signal processor

It’s always good to welcome a new app to the mobile music community, especially one that claims to be exactly for making ‘short and simple’ pieces of music. sequencism calls itself a music sketchbook tool, which is nice idea. According to its creator, the app 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, which is a nice feature.

It’s also worth noting that apparently the main goal of this app is to work as a sketchbook, it is not recommended to use sequencism to produce complex songs or to play songs live on stage. Which is a fair warning I guess.

sequencism features:

• Simple track mixer and visual mixer (volume, pan)
• Multitrack editor: MIDI instrument tracks, chord helper tracks
• Support for SF2* and AUv3 instruments (*lightweight SF2 files only)
• AUv3 Effects
• Piano roll editor: add, move, copy notes within blocks
• MIDI keyboard, supports multiple scales, including user-defined scales
• Support for diatonic and chromatic chords
• Automatic transposing when changing chords or scales
• Supports Audiobus 3 and Ableton Link
• Support for MIDI keyboards, including Bluetooth keyboards
• Export to MIDI

Planned features for the future

• Undo, Redo
• Automation
• Import MIDI files (improve existing support)
