The guys from Xlabz Technologies just posted their new app, Synth Pad, in our forums, so I had to give it go. Synth Pad has a nice UI and feel to in which you'll be able to get making some cool sounds in the first few minutes you try it. I love music creation apps, they are super addicting!
Synth Pad in available for the BlackBerry PlayBook, and you can download it free via App World. If you love the app, be sure to leave a review!
