Cross DJ HD for iPad is a powerful mobile DJ-ing application that supports desktop level functions like: beat-match, auto-sync, effects, loops, scratch, headphones monitoring, MIDI and many more

My Role

I was part of a team formed by 2 iOS developers, 1 UX/UI designer (myself) and during the project I also became the project coordinator. My duty was to co-create the interface architecture, develop a new UI language, coordinate the team and act as a bridge between the team and the CxO level.

The Challenge

Release deadline was 2 weeks with a hard deadline; the winter NAMM show.
I learned that colocation is critical when the project has a hard deadline. Working together and directly with the developers was a success.

We managed to develop and implement the first version of the interface in just 10 days even though, at that time, the term “Agile team” was not so familiar to us.

Simplified and cleaned the track header. Added a clear element hierarchy.
Provided intuitive and innovative pitch bend solution. Easy to use, resembling the hardware turntables.
Created a new concept for pitch value display. Intuitively displayed on the control itself and hidden when it is “zero”.
Improved the Record and Eq functions status display by placing them directly in the tab control.
Optimized performance controls. Ergonomically placed allowing to be used together with effects and while scratching.

My Contribution

  • created the first layout structure
  • designed the graphical user interface and provided initial design direction
  • provided regular updates and maintenance for the various functions of the software
  • conducted user testing sessions that validated assumptions before implementation and reduced the risk for the release
  • developed prototypes and created new ideas for the product
  • created roadmaps for planning and estimated the development time and cost (for releases between 2012 and 2013)

Improved features:

 

  • ameliorating the ergonomics and usability of the user interface and it’s structure compared to the competition
    • clear track info header color and layout
    • library design matching the most up to date iOS paradigms
    • improved sync-meter indicator design validated through user testing
    • UX and ergonomics direction resulting in a more usable software by having the correct set of controls visible at any given moment
  • designed new interaction models that were successfully implemented and adapted to the entire product range of the company
    • easy to control pitch bend solution
    • easily accessible pitch value display
    • record and auto-mix indicators integrated in a seamless way
    • simplification for the audio modes in settings
