Partikl FX Unit: Filter

Filter screenshot, small

Overview

This filter is a very flexible resonant filter. It can work in a variety of different ways depending on how you configure it with the various controls:

  • - Using a fixed filter frequency
  • - Using a built-in frequency sweep
  • - Using a filter frequency that is adjusted dynamically such that it tracks currently playing note pitches.

The main controls in this unit are:

XY checkbox: Checking this will display an XY grid where up/down is Q and left/right is filter cutoff (response times may be slow and "drag memory" long depending on device).

Rate: Determines the rate in Hertz at which the filter sweep moves from minimum to maximum value (and back again) [Sweep check box must be checked].

Range: This value, when added to the Filter Cutoff Min determines the upper frequency for the built-in filter frequency sweep

Cutoff: Determines the minimum frequency for the built-in filter frequency sweep

Filter Type list: Includes Low Pass, High Pass and Band Pass.

Q: the amount of accentuation (resonance) of the filter, 1.0 is the lowest value, and provides low quality filtering with little resonance, 5.0 provides high quality filtering with high resonance, and 10.0 provides the greatest resonance.

Cut: determines the cutoff or center frequency for the filter in Hertz.

Quality: The number of cascaded 12 dB/octave filter sections, defaults to 1. Use a higher value to get sharper cutoff, at the cost of greater CPU consumption.

Phase: determines the phase used by the built-in frequency sweep.

Sweep Checkbox: This checkbox determines whether or not the built-in filter frequency is in use. When not selected, this checkbox disables automatic filter sweeping.

Sync Checkbox: Only relevant when the filter is used with Noatikl part.

Freq Checkbox: When this checkbox is set, the filter frequency actually follows the currently played note pitch, where the note is generated by Noatikl. Tip: setting this checkbox gives a tonal quality to the Filter effect. In this case, the following parameters apply:

  • Octave Offset: This combo-box allows you to specify the octave offset from the current note pitch
  • Semitone Offset: This allows you to select the semitone offset from the current note pitch (taking into account the octave offset above)
  • if Use Notes is set).
  • Micro Offset: This allows you to specify thee microtonal offset in order to 'detune' the filter. The value supplied is in cents (1 cent = 1/100 semitone).

Wet Level: Adjust this value to alter the amount of "wet" (processed) signal in the mix.

Dry Level: Adjust this value to alter the amount of "dry" (unprocessed) signal in the mix.
