4.4. Advanced Mode Control Panel

The Advanced Mode Control Panel is accessed by clicking the Advanced Mode (double

arrow) button in the Upper Toolbar. You can also access it by clicking the "PHASER BI-

TRON" label. This control panel contains very important additions that bring extra power and

flexibility to the processor.

In the case of Phaser BI-TRON, this panel features a Hi-Pass Filter, and several controls

for each of the phaser units: a Poles changer control, two LFO right-channel polarity

invert switches (one for each LFO), and a Mix Dry/Wet control. These bring even more

independence and flexibility to each of the two phaser engines.

This is a 12dB/oct high-pass filter. When you're modulating an audio track with a chorus/

flanger/phaser, you may not want your low end to modulate (like for example if you want

to keep your bass and kick drum steady and precise). That's where the Hi-Pass Filter plays

a role. By filtering out the low regions of the sound at the input of the unit, only the high

frequencies will be modulated.

By default, the filter is Off.

This control selects how many poles are going to be used by the All-Pass filters. The values

vary between two and twelve poles, with the default being six poles. The more poles used,

the narrower the bandwidths and the more intense the comb filtering effect will be.



♪: The original unit filters had six poles. This is also the default value for these controls.
