I am pleased to announce that DOO-DOo-Doo, a finalist at the BlackBerry 10 Jam App Circus, now has a full-featured trial version (limited to 1 minute of usage per launch). The latest version of the app (version 1.1.4) can record up to 90 seconds of playing and supports 8 different temperaments, making it the most versatile synthesizer for kids and singers available on App World to date.
