I thought the feedback or number of repeats only pertained when you used the Boomerang as a delay. I'm trying to use the basic loop function (it should keep repeating until I hit stop). I'll try it again and change the feedback setting but I wouldn't think it would make a difference. Thanks, LeonD > Are you using 100% feedback or a finite number of repeats?
