Info:
Simple FDN slow attack reverb with shimmer feedback loop
The current algorithm topology is:
8 Serial Allpass filters in a feedback loop with Modulation,EQ and PitchShifting - into a 4x4 FDN matrix
FDN is based on the works from
REDUCING ARTIFICIAL REVERBERATION ALGORITHM REQUIREMENTS USING TIME-VARIANT FEEDBACK DELAY NETWORKS By Jasmin Frenette

Reaper JS Version
currently using a small UI/DSP lib: https://github.com/shabtronic/ReaperJSLib
VST2/VST3
uses the marvelous IPlug2 library https://github.com/iPlug2/iPlug2
These use the GPU for UI rendering.
Now working the same as the JS version.
Default
Medium hall type reverb.
Chorus Detune
Poor mans chorus - sounds like a out of tune piano!
Stereo Swell
Medium decay reverb - that pans across the stereo field.
Event Horizon
The classic "Big Space" FDN sound - endless floaty space (almost).
Orchestra Swell
My favourite preset - play with the feedback to control the harmonics and intensity of the swell. Works best with sounds that have low to medium harmonic content (nylon guitar, flute e.t.c.)
Drum Rev
Small reverse rise, that works well with drums and gives a gated reverb effect.
All preset examples are here:

VST2 Version
copy FDNRiser_x64.dll into your normal vst plugins directory, wherever you have previously installed vst2 plugins.
VST3 Version
copy FDNRiser.vst3 into your \Program files\Common Files\VST3 directory (must be this directory apparently).
Reaper JS Version
Simply copy the three files:
"FDN Verb Riser" "FDN Verb Riser.rpl" "stronic-lib.js-inc"
into your \reaper\effects\ directory.
The reverb will then appear in the JS fx list as "FDN reverb riser" once it's been refreshed (either restarting reaper or scan for new plugins).
you may have to import the .rpl into the fx to get the presets.

Add some time change code - resample time, resample pitch or XFade sled - to smooth out any time changes. FPU checks in the VST versions.
