1. If it requires two presses of the STOP footswitch to stop the loop, most likely the Fadeout Time is set to a large number. To disable loop fadeout, do the following: Press and release the MODE knob once, the display should blink a letter. Turn MODE until the letter F blinks. Press and release the MODE knob once, a number should now be displayed. Turn the MODE knob until it displays a zero: 0. Now, when you press the STOP footswitch, the loop should stop immediately.

2. It’s possible that the MODE knob is not changing the loop number. Try the following, press and release the MODE knob once, turn MODE until L is displayed. Press and release the MODE knob again, a number should be displayed. This number now represents your Loop number. You change loop number now by turning the MODE knob. Try recording a loop in Loop 1. Then try recording in Loop 2. Go back and forth between them, you should hear the correct loop audio at each loop number.

One quick test that is worth trying is going straight from your bass into the Bass Preacher into the M-Audio Air. Does the hiss noise level change when the tuner and Digitech pedals are removed?

Also, where do you have the SUSTAIN knob set on the Bass Preacher?

We have two foot trigger product suggestions below. Unfortunately we have not actually tested either of them with the Crash Pad or Super Space Drum.
