Using the Tap Tempo function The average interval (BPM) at which you press the USER DEFINED key will be calculated, and that value will be applied to the BPM parameter. The average interval will be input to the parameter. (the average of a, b, and c) a b c First tap Second tap Third tap Fourth tap NOTE • If the average value is outside the range of 20-300 BPM, it will be ignored. • If you turn on the MIDI CLK button in the special parameter field, the BPM parameter value will change in relation to the tempo of the MIDI timing clock received from the MIDI port. STEP 1. In the Function Access Area, press the RACK button. 2. Press the EFFECT tab in the VIRTUAL RACK window. 3. Press the rack container in which the effect you want to control is mounted. 4. Press the effect type field in the EFFECT EDIT window. 5. In the EFFECT TYPE window, select an effect type that includes a BPM parameter. 6. Set the SYNC parameter ON in the effect parameter field. 7. At the desired tempo, repeatedly press the USER DEFINED key to which you assigned the Tap Tempo function, to set the BPM parameter. Graphic EQ, effects, and Premium Rack Effects and tempo synchronization Some effects of the QL series can be synchronized with the tempo. There are two such types of effect; delay-type effects and modulation-type effects. For delay-type effects, the delay time will change according to the tempo. For modulation-type effects, the frequency of the modulation signal will change according to the tempo. Parameters related to tempo synchronization The following five parameters are related to tempo synchronization. 1) SYNC 2) NOTE 3) TEMPO 4) DELAY 5) FREQ. SYNC This is the on/off switch for tempo synchronization. NOTE and TEMPO: .... These are the basic parameters for tempo synchronization. DELAY and FREQ.: ..... DELAY is the delay time, and FREQ. is the frequency of the modulation signal. These directly affect the way in which the effect sound will change. DELAY is relevant only for delay-type effects, and FREQ. is relevant only for modulation-type effects. How the parameters are related Tempo synchronization calculates the DELAY (or FREQ.) value*a from the TEMPO and NOTE. Turn SYNC ON Change NOTE DELAY (or FREQ.) will be set In this case, the DELAY (or FREQ.) value is calculated as follows. DELAY (or FREQ.) = NOTE x 4 x (60/TEMPO) Change TEMPO DELAY (or FREQ.) will be set In this case, the DELAY (or FREQ.) value is calculated as follows. DELAY = NOTE x 4 x (60/TEMPO) sec FREQ. = (TEMPO/60) / (NOTE x 4) Hz Example 1: When SYNC=ON, DELAY=250 ms, TEMPO=120, you change NOTE from 8th note to quarter note DELAY = new NOTE x 4 x (60/TEMPO) = (1/4) x 4 x (60/120) = 0.5 (sec) = 500 ms Thus, the DELAY will change from 250 ms to 500 ms.
