Tilr has released two open source effect plugins ported from JSFX audio-oriented effects for the Reaper music production software.
GATE1 is an envelope generator for gate/volume control, while TIME1 is a delay modulator similar to plugins like GrossBeat or TimeShaper. It can be used for stutter effects, tape stop, glitch, scratch, reverse, pitch shift and more.
Both plugins come with a multi-segment editor, 12 patterns triggered by MIDI notes, various paint modes and point types, pre and post waveform display, MIDI trigger mode, and more.
GATE1 and TIME1 are available to download as a VST3 plugin for Windows.
