The dev is always right.

I got this app a while ago and was like oh cool it’s a sequencer that’s super super easy to use and super stable and has a generative MIDI thing but it was only until I actually BECAME a HARDCORE iOS musician that I was like oh whoa this thing is now a super super essential tool. I actually also find it super handy to link it with all my synthesizer apps and make infinite generative music for my study time. (I could go buy a generative MIDI app but I already spend $18 on this and it works fine.) So anyway - if you’re not a hardcore iOS studio artist (basically if you haven’t gotten to AUv3 or IAA or Virtual MIDI yet and are just working with GarageBand) you’ll find this app nice, but hard to integrate; it’s not until you expand your digital sonic horizons and get a pro DAW running that you’ll fully realize the potential of Xequence.

Best Linear Midi Sequencer for iOS, period.

While other apps like Quantum and Atom are also excellent in their specific areas, Xequence 2 is hands down the best all around midi sequencer for linear arrangements, and has a lot of loop based features as well. The developer is very active in the iOS music community and has done a commendable job at listening to feedback and feature requests for Xequence v1.

Rather than keep adding IAPs, the app has been rebuilt from the foundation up, and anyone who has spent significant time with the initial app will notice the improved responsiveness, streamlined features and simple but much appreciated new features like:
-Importing midi into an existing project
-Being able to easily time stretch parts from different sources to match the same tempo
- Non-destructive trimming of clips and loops from beginning or end (something that is often surprisingly overlooked.)
I could go on, but suffice to say if you do any serious midi editing on your iPhone or iPad, you owe to yourself to check this out.

Equally useful paired with AUM or AB3, or as a more robust arrangement tool for Gadget, BM3 or Cubasis.

Next Generation of a Wonderful App!

Xequence 2 simply the best midi recording, editing, and playback solution on iOS! It’s become the centerpiece of composing for me. I find the experience far superior to any of the several iOS DAW piano rolls and timelines I own - to the point that I do all my composing in Xequence 2 regardless of the app(s) making the sounds. You do need to know or learn the basics of connecting MIDI between apps, but you need that anyway. ;-)

UPDATE: Since release the app has continually gotten even better. But I also want to say that, honestly, everyone I’ve recommended it to has been thrilled with it. Feedback is virtually all positive on the popular Audiobus forum as well. So, it’s not just me.
