BASIC OPERATIONS - BUILT-IN EFFECTS The Pro Scratch 1™ comes with nine built in effects. These effects can be used one at a time or you may choose to overlap the effects and use up to four at a time. The Built-in effects include Scratch, Fade, Skid, Coast,Flanger, Echo, Robot, Transform, and Pan. It is important to understand that only one effect per an effect bank can be turned on at one time, but all four effects banks can be used at a time. For example the Flanger, Echo, and Robot are all stored in the same effects bank but only one can be used at a time. When any of the effects are activated, the EFFECT (42) icon will display in the LCD (1). You can choose to use the effects with their default setting or you may choose customized each effect by changing the parameters. The parameters values for all the effects will range. Some effects will have more adjustable parameters than others. The parameters have two adjustable values, PR (Parameter Ratio) and PV (Parameter volume). All parameters will be reset to there default values when power is shut off. American DJ® AUDIO • Pro Scratch 1™ INSTRUCTION MANUAL • PAGE 21 SCRATCH/FADE EFFECT: The Scratch effect simulates real time turntable scratching. The fade effect fade the volume in and out. Pressing SCRATCH/FADE BUTTON (4) once will activate the scratch effect (figure 43). When the Scratch Effect is activated the SCRATCH/FADE BUTTON (4) will glow. To activate the Fade Effect, be sure the scratch effect is off and press and hold the SCRATCH/FADE BUTTON (4) until it begins to flash. A flashing button will represent the Fade Effect is active. The fade effect will fade the music out and bring back in. The fade time can be adjusted in the parameters setting from 0010 to 9990. 9990 will give you the longest fade out time. The fade value ranges from 10ms to ten seconds. Figure 43 Figure 42 Activating Parameter Mode: All the effects have adjustable parameters. The parameters change the way the effect will react. To enter the parameter mode for any of effects, press the PARAMETER BUTTON (28) as in figure 42. When the parameter mode is selected the time display in the LCD (1) will change to indicate the parameters. Some effects have more adjustable parameter than others. Pressing the PARAMETER BUTTON (28) more than once will advance you to the next parameter adjustment, if there are no other adjustable parameters pressing the PARAMETER BUTTON (28) will return the time display in the LCD (1). Figure 44 HOLD BUTTON: Use the HOLD BUTTON (2) to lock your customized parameters. If the hold button is not activated any changes to your parameters will be momentary.

BASIC OPERATIONS - BUILT-IN EFFECTS FLANGER/ECHO/ROBOT EFFECT: The flanger effect distorts the output signal and create an effect similar to the frequency phasing in and out of each other. The ECHO effect adds an echo to your output signal. The ROBOT effect distorts the output to simulates a sci-fi robot voice. When the FLANGER effect is selected the FLANGER/ECHO BUTTON (30) will glow. When the ECHO or ROBOT effect is selected the FLANGER/ECHO BUTTON (30) will flash repeatedly. ROBOT EFFECT: The ROBOT effect is activated in the ECHO parameters. To activate the ROBOT effect select the ECHO effect. After the Echo effect is activated enter the PT Parameters and turn the hold function on. Set the Parameter Time (PT) value to 0010 and use the Jog Wheel to create the effect by adjusting the Parameter Ratio (PR). FLANGER EFFECT: The FLANGER Effect has two adjustable parameters, Parameter Time (PT) and Parameter Ratio (PR). The PT will adjust the Flanger Mode and The PR will adjust the Flanger Frequency Range. ECHO EFFECT: The ECHO Effect has two adjustable parameters, Parameter Time (PT) and Parameter Ratio (PR). The PR will adjust the length of the echo (drop off time), and the PT will adjust the echo gap length. TRANS/PAN EFFECT: The TRANS effect simulates a real-time mixer transformer effect. The PAN effect allows you to pan the output from the left channel to the right channel. Pressing TRANS/PAN BUTTON (29) once will activate the TRANSFORMER effect (figure 47). When the TRANSFORMER effect is activated the TRANS/PAN BUTTON (29) will glow. To activate the PAN effect, press and hold the TRANS/PAN BUTTON (29) until it begins to flash. A flashing TRANS/PAN BUTTON (29) will represent the PAN effect. The fade time can be adjusted in the parameters setting from 0010 to 9990. 9990 will give you the longest fade out time. The Pan Value ranges from 10ms to ten seconds. TRANS EFFECT: The TRANS Effect has two adjustable parameters, Parameter Time and Parameter Ratio. The PT will adjust the Trans Speed and The PR will adjust the Trans Audio Length. The lower the PT value the faster the TRANS effect (PT 0500 = 1/2 second, PT 1000 = 1 second). PAN EFFECT: The PAN effect uses the PT value to pan left to Right. PT 0500 is the default setting which is center pan. Figure 46 Figure 45 Figure 47 American DJ® AUDIO • Pro Scratch 1™ INSTRUCTION MANUAL • PAGE 22 SKID/COAST EFFECT: The Skid effect simulates the sudden platter stop of a turntable, like pressing the stop button on a turntable. The COAST effect simulates a turntable slowly revving up to it's proper speed, or slowly winding down to a stop, like tuning the power off when a turntable is running. When the SKID effect is selected the SKID/COAST BUTTON (3) will glow. When the COAST effect is selected the SKID/COAST BUTTON (3) will flash repeatedly. The fade effect will fade the music out and bring back in. Both the Skid and Coast time parameters can be adjusted from 0010 to 9990. 9990 will give you the longest Skid and Coast times. The SKID/COAST value ranges from a 10ms to ten seconds.
BASIC OPERATIONS - FX MIX American DJ® AUDIO • Pro Scratch 1™ INSTRUCTION MANUAL • PAGE 23 Figure 49 Figure 50 Figure 48 FX MIX MODE: This function allows you to use the effects to transfer from one track to another, one track to a sample, or one sample to another. FX Mix uses the effects and the FLASH BUTTONS (6). The FX Mix function will only work with samples and cue points programmed in the any of the three FLASH BUTTONS (6). The procedure below list the steps to activate the FX Mix Mode. In the following example we will you the SKID Effect to transfer from one track to a programmed sample. STEP ONE: Be sure you have created a sample and stored it in to the FLASH 3 BUTTON (6)(see creating a sample on page). After a sample has been created and store, begin playback on a track. Select the FX MIX BUTTON (11) to activate the FX Mix Mode. STEP TWO: After you have activated FX Mix Mode, select an effect. In this example we will choose the SKID Effect. Choosing the SKID Effect we create a braking effect. STEP THREE: When you are at the point in the track you wish to begin the sample, press the FLASH BUTTON 3 (6). Pressing the FLASH BUTTON 3 (6) will now end the current track and beginning to play the sample stored in the Flash 3 bank. The track will end in a brake effect and then immediately being to play you stored sample in Flash Bank 3. STEP FOUR: To initiate the FX Mix , tap the BOP/ENTER BUTTON (20). At this point you may continue the FX with the current track. If you follow steps one and four, you will initiate the FX mix on the current track. For example; If you used the brake effect for your effects mix, following steps one and four will initiate a brake effect in current track and then continue with the track once the brake effect has ended. You must be in continuos play mode for this effect to operate properly.

MATCHING THE BEATS PER MINUTE (BPM)
Beat matching is the act of finding the BPM’s (beats per a minute) of two different music sources, and
matching them together. After you have matched the BPM’s you use your mixer to fade the volume
in and out of one song to the next without music interruption while retaining the same beat. Use
the PITCH SLIDER (17) to match the BPM’s of one PRO SCRATCH 1™ to that of another PRO
SCRATCH 1™ or other music source. Use your mixer's crossfader to blend them in to each other
seamlessly. This is a function that may take some practice.
