In Master Effect B window theres a 'delay time' setting.
Check this site:
http://deepsound.net/calculs.html
Near the bottom is the Delay and Frequency calculator
enter the bpm of your track
It will give you a choice of settings for the delay time setting!
Also just realized you can sync your LFO's quite closely using this calc - just use the hz settings! Posting seperate topic on that one...
A good calculation page

Any probs, let me know.
