RV7000 MK II ADVANCED REVERB

Convolution
The zero-latency Convolution algorithm uses impulse response samples to generate effects. Basically, “convolution
effects” are the results of multiplying the frequency spectra of the input signals with the frequency spectra of impulse
response samples, and thus generating a signal with the “character” of the impulse response sample. If the impulse
response sample is a recording of the reflections of a large room, for example, the resulting effect will be “the input
audio signal played back in a large room”.
RV7000 Mk II comes with three built-in preset impulse response samples. You can also use any other samples for
the convolution algorithm, to generate all kinds of reverbs and special effects. You can even sample your own im-
pulse responses and use in the convolution algorithm in RV7000 Mk II.
q Propellerhead have gathered a large number of impulse responses and collected them in a free ReFill, along
with lots of patches for the RV7000 Mk II and the Combinator. The ReFill is called "RV7000 mkII patches" -

Note that in the Convolution algorithm the input signals for the effect are first summed to mono (except in Parallel
Stereo Mode (see “Stereo Mode”)) and then processed with the impulse response sample. The figures below shows
the signal routings in the Convolution algorithm:
In the remote panel, the Convolution algorithm has the following parameters:
Density Density governs the “thickness” of the Reverse effect. If this parameter is turned down to zero, the effect produces
individual delays rather than a dense “wash”, which can be used as a special effect. Worth noting is that if Density
is set to around 50%, this can considerably reduce the CPU load without altering the sound of the effect too much.
Exactly how much the Density parameter can be reduced without altering the sound depends on the source mate-
rial.
Rev Dry/Wet Sets the balance between the “moved” source signal (“dry”, low values) and the reverse reverb (“wet”, high values).
Tempo Sync Determines whether the Length setting should be freely set (“off”) or synchronized to Reason’s tempo (“on”).

Description
Sample Preset Here you select one of the preset impulse response samples - plus your own sample (if you use that, see “Loading
impulse response samples”).
Length Sets the length (end point) of the currently used impulse response sample.
