Thesys is an extremely powerful and intuitive MIDI Step Sequencer app, giving you control over just about all aspects of your favorite MIDI devices. Use Thesys to create varied and organic bass lines, screaming leads, pulsating chords, and organic pad sounds in the studio or on stage. For live musicians, Thesys provides an extremely versatile palette of performance options which can be triggered right from your MIDI keyboard: you can transpose, manipulate, twist up, mutate, and mangle your patterns without even getting near your iPad.

Ratings and Reviews
AUv3 update is transformative
The latest update to AUv3 has made it possible to run multiple instances of Thesys inside a NanoStudio 2 session, so you can compose multiple melodic parts together. The desktop interface is quite tiny on an iPad, though—if you have an Apple Pencil, you’ll want to use it.
The best step sequencer, maddeningly tiny interface
This is the best featured step sequencer in iOS, to this day. Has a bunch of modulation lanes, 32 steps, independent lengths for different parameters, scale quantize, scalar transpose, song mode, dj-style midi effects. All amazing, next level stuff, crammed into the most uselessly tiny interface, and ill conceived zoom workarounds. Be ready for bumping adjacent controls all the time and screwing up your sequence. I use it sometimes, and it ends up sounding great, but I loathe the experience. It doesn’t need to be this tiny, there is all kinds of wasted space, and needlessly compacted, dangerous to mix up groups of buttons, in fields of unused white space. It was ported from the desktop, and was never designed for a touch screen. If you could expand the sequencers to fill the screen you would be set, I think. Replace the dreadful PC key modifiers, Cmd, Ctrl, Alt, with traditional touch interface modifiers, like tap and hold, double tap, etc.
In an effort to use the app, I’ve gone to great lengths to midi map the controls to a midi controller, but, there is no way to reuse the midi mappings from one project to another, and there is no default mapping.
I would avoid this app on anything except the 12.9” iPads.
Great AUv3 MIDI Sequencer
The update to the app is an excellent upgrade to the functionality of the app. You can easily create all sorts of musical mayhem by running multiple instances of the app and can change sequences on the fly via the GUI or use MIDI to control the app’s parameters.
With Family Sharing set up, up to six family members can use this app.
