•
Scratch: This effect alternates between normal and reverse playback of each beat, creating a
vinyl-scratching effect.
•
SendRtn (send/return): This option will enable the send outputs and receive inputs, allowing
you to use external effects on the signal.
All of the BPM effects are time-based, so the BPM effect module offers several ways for you enter or
detect the tempo it will use.
To adjust the time division of the BPM effect module, do either of the following:
•
Make sure the time division (__ Beat) is selected in the lower display (if it is not, press
the FX Time knob), and then turn the FX Time knob to select another time division.
•
When the Instant button is off, tap an area of the FX touch strip to select a time division.
A corresponding light along the strip will illuminate to indicate the current time division.
To adjust the rate of the BPM effect module in milliseconds, make sure the millisecond rate
(__ ms) is selected in the lower display (if it is not, press the FX Time knob), and then turn the
FX Time knob to adjust it.
To enter a new tempo, press Tap at least 3 times at the desired tempo. This will set the rate of the BPM
effect module for the channel set by the FX Channel Assign knob (the module's rate for other channels
will remain unchanged). The Tap button will be dimly lit when using a BPM manually entered this way.
To detect the tempo automatically, press and hold Tap/-Auto for 1 second. This will synchronize the
rate of BPM effect module with the audio signal of the channel set by the FX Channel Assign knob (the
module's rate for other channels will remain unchanged). The Tap button will be brightly lit when using a
BPM automatically detected this way, and Auto will be shown next to the BPM in the second display.
Note: If you are using an SC5000 Prime unit with Engine Connect, the SC5000 Prime will control
the BPM effect module, and the Engine logo will be shown in the second display.
To adjust the tempo manually, press and hold Tap/-Auto, and then turn the FX Time knob to
adjust the BPM in increments of 1. While still holding Tap/-Auto, press and turn the FX Time knob
to adjust the BPM in increments of 0.1.
You can easily adjust the balance between the "wet" signal (the BPM effect module's output signal)
and "dry" signal (audio without effects applied).
To adjust the balance between the "wet" and "dry" signals, turn the Wet/Dry knob. Alternatively,
use the FX touch strip while in Instant FX Mode (see below).
Normally, you would apply effects to the entire frequency spectrum, but X1800 Prime also lets you
apply them to an isolated frequency band of the audio signal (of the selected channel).
To select the frequency band, turn the FX Frequency knob. Select the center (12:00) position
to apply effects to the entire spectrum of frequencies.
Instant FX Mode enables you to use the FX touch strip to activate the effect and adjust its time
division simultaneously.
To enable or disable Instant FX Mode, press Instant. The button will light up when it is enabled.
To activate the effect, tap and hold your finger on the FX touch strip, and then drag your
finger up or down to adjust the time division of the effect.
Sweep FX
Sweep FX enable you to apply one of four effects to the four channels and "sweep" them using the
Sweep FX knobs. You can apply only one sweep effect at a time.
To activate a sweep effect, tap one of the Sweep FX buttons: Dub Echo, Noise, Wash Out, or
Gate. The button will light up when activated. Only one of these buttons can be enabled at a time.
To deactivate a sweep effect, tap the lit Sweep FX button. Alternatively, press a different Sweep FX
button to activate it, which will deactivate the other.
