Thesys 4+

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.

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.

How can you how can you delete something, on iPad - on computer it’s right click. Not able to on iOS.

Edit - nvm I figured it out. Long press. Great stuff.
