Turn on your BR-1180 and engage the Rhythm Guide feature by pressing and holding the "Stereo Rhythm/Loop Edit" button. The button's LED will become red.
Press and hold the "Stereo Rhythm/Loop ON/OFF" button. The button's light will turn red and the device will begin to play the currently programmed drum loop.
Use the arrow buttons on your BR-1180's directional wheel to select "Arrange," then twist the "Time/Value" dial to your preferred arrangement. Touch "Tap" repeatedly to change the tempo, and slide the "Stereo Rhythm/Loop" lever to raise or lower the volume.
Return to normal operation with Rhythm Guide on by pressing "Stereo Rhythm/Loop On/Off" again. The button's LED light will turn red to go into automatic mode.
Press "Exit/No" and you'll be at the main display.
Press "On/Off," just above the fader. Press "Play." To select another arrangement, press "Stop," then turn the "Time/Value" knob for another drum loop. Press "Zero" to start at the beginning of the song.
Select your final drum arrangement by using the directional arrows to highlight "BPM" (beats per minute). Turn "Time/Value" to tweak the loop's tempo.
