FILT-R is a cross-platform filter modulator based on plugins like ShaperBox and FilterShaper. It includes 6 unique filters, three of them grabbed from Saikes Yutani Bass (303, MS-20 and Linear), a Moog filter which is the JUCEs stock ladder filter adapted to this project and finally an Analog/Sallen Key and Phaser filters which came from Vital synth source code.

Features
6 Unique filters with different slopes and modes
5 Modes per filter (LP, BP, HP, Notch and Peak)
12 patterns for resonance and cutoff triggered by midi notes
Paint mode with user defined shapes
Point type – hold, curve, s-curve, stairs ..
Built-in sequencer and randomizer

Paint mode
Paint mode was remade in version 2, it now works with custom patterns that can be edited like the main audio patterns and rescaled before placing on view. There are 32 patterns that can be used and edited, these patterns are saved in the settings file and shared by any instances of the plugin.

Envelope Followers
Envelope followers for cutoff and resonance can be activated in the Envelope section by setting the amount positive or negative. This feature like many others was introduced by ShaperBox and had to be included in this project.

Self repeating patterns
Patterns are not constrained by start and endpoints like they used to, they can have only one point or no points, this mainly allows patterns to be seamlessly rotated to create new rhythm variations.

Multi-point selections
Multiple points can be selected and moved around, the selections can also be scaled and skewed by holding Alt + drag the leftmost or rightmost handles, this allows to quickly make rising or falling wedges as well as compress or expand sets of points.

Audio Trigger
Audio transients can be used to trigger the envelope or restart its cycle, its heavily based on ShaperBox and includes two modes of detection: Simple – based on envelope following and Drums – based on total energy during a small time window. This feature is also heavily based on ShaperBox and also allows to use sidechain as input.

MIDI Trigger
MIDI can be used to trigger the envelope or restart its cycle, it can also be used to change patterns (defaults to channel 10).

Pattern sync
Pattern changes can be synced to the playback beat position, this allows for to make timely transitions in real time in sync with the song position.

Sequencer
Clicking the Seq button toggles the sequencer mode where patterns can be built and randomized with ease.

Tips
Shift for fine slider adjustments.
Shift toggles snap on/off.
Mouse wheel on view changes grid size
Right click points changes point type.
Alt + drag selection handles skews selected points.
Right click + drag in paint mode changes paint tool tension.
Shift + mouse wheel on sequencer to change step size.
