What’s New

I Thought I Needed This But Then I Got It And It Wasn’t Shat I Expected But Then I Still Needed It ‘Cause It’s Amazing.

I was looking for a better alternative to GarageBand as my hub for music production so I downloaded this program thinking it was a DAW. I was wrong so I was a little off put by the fact that I spent $18 on something I didn’t need... but THEN as I started further playing around with it and checking out features like PolyHymnia I was all like whoa this is freaking awesome. I also found a way to use it with GarageBand - importing and exporting midi files is one, and also I can record live over inter-app audio by setting up an instrument with GarageBand and having a sequence I’ve built on Xequence, or multiple sub sequences (eXtReMeLy helpful feature), control my instrument.

I’d also have to agree with the rest of my fellow reviewers that this app is extremely solid and very easy to use. It works better than any desktop DAW or sequencer I’ve used. Kudos to the developer and may your developership be happy and prosperous! :D

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.

Everything I’ve tried so far has worked very logically and as expected. It’s difficult to imagine how something this complex could be so intuitive. Everything I’ve looked for has been within easy reach, and new features are clearly spelled out in the manual (an absolutely thorough document). I opened it up to try it out (I was previously a version 1 user), and before I blinked I was cutting and pasting pieces and sending MIDI to 4 different synth destinations. Thanks for an EXCELLENT product!
