Switching in synchronization with music
Using the tap (TAP) function to switch images
As an alternative to specifying the BPM numerically, you can use the tap button (TAP) to specify
the timing at which the images will switch.
1. Input images to channels A and B.
Use the channel A and B input selectors to input images into each channel. Input different images
into channels A and B.
2. Press the BPM sync button (BPM SYNC).
Press the BPM sync button. The images will begin switching at the BPM timing shown in the BPM
indicator.
3. Press the tap button (TAP) in time with the music.
Play back the desired background music, and press the tap button in time with the beat. The BPM
readout will be constantly updated to reflect the timing you use while tapping the button, and the
images will switch according to this BPM.
