Reply to Omni Control and Traktor pro 1.2.4

Hello, everyone! I have such problem: i use my omni control with traktor pro 1.2.4 with standart mapping...I install traktor pro 1.2.4, choose my controller in menu, make audio setup...that's all! All buttons and functions work good except auto loops. What buttons activate autoloops and change loop length (1,2,4...)?
