This app appeared on the 30th and I haven’t had a chance to take a look yet, but it does seem to have an impressive list of features. Here’s the description:

Launch the Rhythm Trax app, drop in loops, add effects and create your next smash hit. Rhythm Trax takes mobile music production to the next level. Once your audio masterpiece is complete, export it and share. Rhythm Trax is music made easy.

This app is designed for the iPhone 4 only.

Rhythm Trax is a hybrid loop / sample sequencer. On the surface, it is a very easy to use loop sequencer. Digging deeper into the app, you will find very advanced editing features.

With Rhythm Trax, you take loops and drop them into a timeline. No need to worry about loops with different tempos, Rhythm Trax automatically adjusts everything for you in real time. You can drop any loop onto any one of eight tracks. Each track has it’s own mixer channel with dedicated effect. Effects and volume can be automated per loop and per track. Create epic filter sweeps or transforming variations to your sounds. Use the provided loops or easily import your own via iTunes or Intua audiopaste.

If just arranging loops isn’t enough, double tap any loop on the timeline and rearrange the loop slices and pitches to create new remixes. Bounce out loops and entire song steps for even further editing.

With file sharing supported by the latest iOS, importing/exporting between your device and your computer are now easy. The days of file transferring over wifi or some 3rd party software are over.

  1. You can't use this app on the iPad for some reason. It looks interesting but the UI seems a bit confusing. The only A4 based device I own is the iPad so I'm forced to pass on this.

  2. It doesn't look particularly intuitive. Actually I probably mean aesthetically pleasing. It doesn't look nice at all. Does it matter? I can't help but judge a book by it's cover, sorry. Sounds good on paper though.

  3. The only thing I find interesting about this app is the loop slicing. And I wouldn't even bother slicing beats but would rather slice up vocals and field samples.

    But no option for reverse. Pretty limited for 6 clams, imo.

  4. Beyond the look, the sound in that video is tinny and lame. I see some potential in this thing, but feel a high risk I'd be wasting $6 and crowding my device all the more.

    I'm amazed these app people don't create lite versions so you can try it out or provide more thorough demo on their sites or YouTube.

    Most certainly have to pass here but would love some detailed comments from those who've bitten.
