The delay time of the following three effects is determined by the "Tempo" and "Note" parameters, so you can easily match the delay time to the tempo of the music. Tempo Mono Echo (TmpEchl) Creates a single delay with stereo output. 1in/2out Tempo Stereo Echo (TmpEch2) 2in/2out Produces a separately processed left and right channel stereo echo. Tempo Quad Echo (TmpEch4) 2in/2out This program produces an echo effect that used to be possible only with four delay effect machines. Four delay lines are controlled in pairs. • How to input the "TEMPO" parameter One of the following five methods can be used to input the "Tempo" parameter. • Manual Input You can set the Tempo like any other parameter by inputting a numerical value in the edit mode. • Tap Input (Function Key) The tempo can also be set by pressing a function key twice in succession in the edit mode. The interval between the two key operations determines the Tempo value. • Tap Input (Footswitch) Instead of a function key, a foot switch conected to the rearpanel TRIGGER terminal can also be pressed twice in succession. • MIDI Clock Input The Tempo value may also be set using the MIDI clock of a connected device. • MIDI Control Change The Tempo parameter can also be controlled via MIDI control change messages like any other parameter. The input methods available depend on the setting of the "Trig." parameter. SETTING OF "Trig."

To set a delay time matching the tempo of the music, you just press the foot switch twice for a one-beat interval. This eliminates a troublesome parameter setting in the edit mode. What you actually set by tap input is not the delay time but the tempo. The delay time then is calculated based on this Tempo value and the Note value, which must be set in advance. When you tap input using the "TapKey" display, a bar graph indication shows the time elapsed since the first function key or foot switch operation. One bar equals 250 msec (50 msec per vertical line). Please note that the bars will disappear, if the maximum allowable delay time is exceeded before you press the function key or foot switch a second time. • Tap Input using a function key Tempo EJ=12I3 • A P [ 4,1= 9ci "Tempo" value after Tap Input. Ta F PRESS I The interval between the two key operations determines the delay time. Ta PK orm Indicates the time elapsed since the first function key operation. PRESS I • Tap Input by Foot Switch TAP TAP • The delay time (Tempo) can also be set by pressing a connected foot switch twice. The interval between the two foot switch operations determines the delay time. 34
