Sketch Audio’s filter plugin Series 9000 is currently available as a free download!
In this article, we’ll go over the giveaway details and an overview of Series 9000.
What Is Sketch Audio “Series 9000”?
Series 9000 is a filter/distortion plugin that recreates the steep sixth-order (36 dB/oct) low-pass filter sound made famous by rackmount samplers of the late 1980s.
Main Features
- Recreates the sixth-order low-pass filter sound made famous by late-’80s rackmount samplers
- Cutoff: the minimum cutoff sits at around 300 Hz, so the core of your sound stays intact even with the filter fully closed
- Drive: a saturator built into each filter stage — completely clean and linear at 0.0 dB
- Q: filter resonance
- Env: an envelope follower that modulates the cutoff, with adaptive release
- Light and dark color schemes
