In this free video tutorial, Pro Tools Expert Team member Julian Rodgers looks at the free Subfilter plugin from Plugin Alliance. This Plug-In offers a resonant high pass filter in combination with an adjustable band pass filter centred on 55Hz which, in combination offer useful control over the bottom end of mixes and individual instruments.
A Free Version Of The Filter Section Of Subsynth
This plug-in is almost identical to the filter section found in the Plugin Alliance Subsynth but adds a three position resonance control, allowing the frequencies just above the cutoff frequency of the high-pass filter to be accentuated, or exaggerated, depending on which setting you choose. Use with care!
