Q. Where's the time knob? How do I control the decay time / RT60?
A. The decay time was intentionally left out following the reverb's design philosophy that the physical properties such as wall/material absorption, atmospheric attenuation, energy conversation in higher-dimensional spaces are transparent at the expense of some user friendliness (apologies!). To increase the decay-times, decrease (turn right) the dB loss of each dimension's boundary, decrease the low-damp (turn left and set to 0 actually), and increase the geometry scale (turn right).
Q. I want insta diffuse reverb. Early reflections get in the way. How do I remove them?
A. One way is to bias the sampling of the geometry by turning the sampling knob left. This causes earlier reflections in the space to scrunch together in time, removing any build-up time towards the denser tail, giving the impression that the space is like a plate. Conversely, turning sampling towards the late undersamples the early and elongates the late, causing the buildup of reflections to be stretched like a creshendo.
Q. Some settings sound metallic? Where's the modulation knob?
A. No modulation capabilities due to this being part convolution reverb. Metallic parts may occur during the early portions but can be mitigated by increasing the high-frequency damping factor.
Q. What controls can I automate?
A. Controls outside the Misc. panel cause a recalculation of the reverb stream. Although done in a separate thread, the wait-time varies by parameter setting and your rig's compute power. Controls within the Misc. panel are done within the processing buffer and ought to be smooth enough for automation.
Q. Why are there different depth parameters?
A. The depth per spatial dimension represents your (the listener) Cartesian coordinate within that space. Depth = 0 across all dimensions means you're at the voom's center. Depth = max across all dimensions means you're in a corner. In general, a more centered position increases time between direct and onset of early reflections.
Q. So many stereo knobs. What're their signal processing chain?
A. In the processing order: Convolution output -> Haas & Pan -> Phase Offset-> Stereo Mid/Side -> Gain -> Mix. This means that stereo mid/side can either "mono-ize" (turn left) or widen (turn right) left/right delayed & gain adjusted streams from Haas /Pan and phase offset processors.
Q. Are there ways to control CPU usage?
A. Increasing the max FFT block size will decrease the average CPU load at the cost of occasional CPU spikes. The degree of the CPU spike depends on the length of the reverb and your CPU build. Conversely, decreasing the block-size will even-out the CPU spikes at the expense of higher average CPU load. Last, another trick is to gate the reverb tail by raising the onset and reverse knobs to a larger percent. By default, the tail is computed for RT120 unless it hits a 5 sec limit when geometry scale is set to 1 (can be raised to 20 sec by increasing scale). You can cut the impulse response time in half by setting onset and reverse to 50%.
Q. What settings should I use to make super-lush tails for ambient pads
A. A super-dense tail that swells will do the trick. Enable all V1 to V5, increase the listener depth, vary the size of each dimension a bit, drop low-damp to 0, increase high-damp, turn down attenuation a bit and force sampling towards late. Last boost the gain if RMS normalization is on.
Q. Gated Reverb?
A. Bring up onset and reverse knobs towards 100%
