Thesys is an extremely powerful and intuitive MIDI stepsequencer 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. No other MIDI sequencer plugin offers you the ease and power of Thesys. It is 100% MIDI compliant and therefore provides the ultimate MIDI sequencing solution.

Powerful sequencer in need of some interface tweaks
I thought long and hard about whether to try out Thesys. Eventually, my curiosity got the best of me. On the plus side, it has a TON of features, but excels at monophonic basslines and leads. There is a chord feature that is pretty neat, but primarily, it is monophonic. The best feature is probably that it has a built-in synth engine within the app. And the sounds aren't half bad. You can audition them, or even export them through AB, etc., as a final product.
But the interface is just largely awful. This is obviously a VST port from PC with little re-imagination done as to how it would control on an iPad. (This is true of all the SugarBytes apps). So, the actual part of the screen the contains which notes play in your sequence probably uses 20% of the screen space. You can double that with a magnifier, but it is clumsy and akward. Also, I'm not sure the app either does "Open In" with MIDI files, nor could I find that it exports raw MIDI data. I could be wrong on the latter point, but those are features that would have been nice for a premium app such as this one. Overall, it's intriguing, but still a bit flawed.
This app really puts a new twist on how midi can be used on iOS. While the port from the desktop plugin doesn't take full advantage of what the iPad can do, you can still get lots of use out of it. I especially like both the Audiobus and Jack support.
I did have some issues with some synth apps that didn't seem to play well with Thesys, but that is par for the course and hopefully they'll be able to work this out in updates.
It will take some time to learn how to use all of the features of the app, but even in the first few minutes of use I could see features that are very useful such as the ability to copy whole or parts of patterns. The ability to access all of the cc messages is much more straight forward than in Genome Sequencer.
Another great(ish) Sugar Bytes app
This is definitively the most encompassing and powerful stepsequencer you'll find on the AppStore. But just as their other Mac/PC port of Turnado the interface didn't go through any design changes for the iPad version. You gonna need to use that double tap to zoom function for sure, and as with Turnado it will constantly keep zooming in when you do not want to use it. And turning it off is not really an option with this one since everything is really tiny. So a slider (or some other solution) that determines how fast/slow you need to double tap is definitely needed here to get rid of this big design miss/frustration generator. Also, the PC buttons need a toggle mode option. 5 stars from me when that's taken care of.
With Family Sharing set up, up to six family members can use this app.
