Note that while this kind of real-time playing can be fun, the most common filter application is to add dynamic effects by controlling it with a signal such as input dynamics or an envelope. This routing would be done in the Modulation Matrix.
MODE GENERAL EFFECT WHAT FREQ DOES WHAT Q DOES
lowpass 4 pole
reduces highs
rolls off highs at 24dB/octave starting at the selected cutoff freq rolls off highs at 12dB/octave starting at the selected cutoff freq
boosts response at the cutoff frequency and slightly lowers the level of frequencies below the cutoff frequency boosts response at the cutoff frequency (but more gently than 4 pole mode), and slightly lowers the level of frequencies below the cutoff frequency boosts a range of frequencies centered at the freq parameter narrows/widens the range of frequencies
lowpass 2 pole
reduces highs more gently than 4 pole mode
bandpass 4 pole
boosts a range of frequencies
boosts a range of frequencies centered at the freq parameter boosts a range of frequencies centered at the freq parameter rolls off lows at 24dB/octave starting at the selected cutoff freq rolls off lows at 12dB/octave starting at the selected cutoff freq
bandpass 2 pole
boosts a range of frequencies, but with a wider slope reduces lows
highpass 4 pole
boosts response at the cutoff frequency and slightly lowers the level of frequencies above the cutoff frequency boosts response at the cutoff frequency (but more gently than 4 pole mode) and slightly lowers the level of frequencies above the cutoff frequency
highpass 2 pole
reduces lows more gently than 4 pole mode
The Active button turns the filter on and off. If you don�t need a filter, turn it off to reduce the stress on your hard-working CPU. This will cause it to like you.
