ValhallaDSP ValhallaShimmer VST RTAS v1.02

At its core, ValhallaShimmer is a high quality reverberator, designed to
produce a smooth decay, that is both dense and colorless. There are several
reverberation modes available, to allow the user to dial in reverb decays
of different sizes, ranging from smaller rooms to vast ambiences.

By adjusting the Feedback, Diffusion and Size controls, the attack, sustain
and decay of the reverb signal can be fine tuned.

The modulation controls can be set to produce subtle mode thickening,
glistening string ensemble-esque decays, and the distinctive random
modulation of the older Lexicon hall algorithms.

Two tone controls and the Color Mode selector allow the timbre to be
adjusted from bright and glistening to a more natural dark decay, similar
to that produced by air absorption in large spaces.

In addition, ValhallaShimmer has the ability to pitch shift the feedback
signal. There are 5 pitch shift modes available:

Single, where the feedback is shifted up or down by the Shift value.

By setting the Shift amount to +12 semitones, and the Feedback to 0.5 or
greater, the classic "shimmer" sound is produced, as heard on Eno / Lanois
productions for U2 and others. A wide variety of other sounds can be
created by the algorithm, ranging from spring-esque reverbs to "reverse"
reverbs, to glistening pitch shifted pads that are usually associated with
high end hardware processors.

ValhallaShimmer has been designed to be tweaked in real time. All of the
sliders have a smoothed response, to avoid clicks when changing settings or
automating the controls. At the same time, the algorithm has been highly
optimized, so you get a huge reverb sound without straining your CPU.

The algorithms in ValhallaShimmer are the results of over a decade of
research into both reverberation algorithms and pitch shift algorithms. I'm
proud of the results, and am excited to hear what you will create with this
tool.

Dual, where the feedback is shifted both up and down (in parallel) by the
Shift value.

SingleReverse, where each grain is reversed before it is pitch shifted.
This results in a smoother pitch shifting sound than the Single mode.

DualReverse. Similar to the Dual mode, but with reversed grains, for a
smoother pitch shifting sound.

Bypass, which turns off the pitch shifting (useful for ôstandardö reverb
sounds).
