• Feedback. Adjusts the amount of the filtered output signal to be fed back into the
input. Variable from 0 to 95%.
• Stages. Adjusts the number of allpass filter stages for the phaser. Variable from 2 to
20.
• Spread. Adjusts the spread of each delay stage from 0 to 100%
• Depth. Adjusts the mix of the processed phaser output with the original dry input
signal. Variable from 0 to 100%.
13.9.5 X-Trem
X-Trem is a tremolo effect that applies amplitude modulation at a varying amount and rate
over time. The X-Trem features tempo sync and a variable LFO with selectable 16-step and 16-
gate sequencers, as well as auto-pan capability. Use Tremolo on any track to create anything
from subtle shifts in amplitude to tempo-synced, glitchy, gated drums; trancy, gated pads;
panned hi-hats; and other popular sounds.
The following parameters are available for the Tremolo:
• Depth. Adjust the relative amount of maximum amplitude modulation. Variable from
0 to 100%.
• Speed/Beats. Adjust the speed of the LFO.
o
Sync. Click to engage LFO tempo sync. Time will be expressed as Beats.
o
Speed. Variable from 0.01 Hz to 30 Hz.
o
Beats. Select from 4/1 to 1/64 with triplet and dotted-time variants.
• Pan/Trem. Click to switch the mode of the Tremolo to affect overall amplitude (Trem)
or the left- and right-channel balance (Pan). Pan is only selectable on stereo tracks.
• LFO Mode. Select from triangle, sine, sawtooth, or square LFO waveforms or a 16-step
or 16-gate sequencer.
o
16 Steps. Click in the LFO display to adjust each step. The steps divide the current
Speed/Beats time value; the value of each step represents amplitude/pan at that
step from 0/hard left to 100%/hard right.
