Yes, I thought someone would want to know what the Reverb Cluster Proportion is. Interestingly, it represents the proportions of the room or 'reverb medium’, to use Dynacord’s term. Let me quote the manufacturer’s descriptions since they are the people who ought to know what the unit is meant to be imitating: &ldquo'Cathedral’ is, acoustically speaking, a very favourable block-shaped room (e.g. church, cathedral. 'Cave’ is a relatively low room (e.g. subterranean garage, cellar). 'Cube’ is an even cube-shaped room (e.g. a small but high room, a high warehouse). 'Tube’ is a long almost cylindrical room (e.g. subway, tunnel, bunker, wine cellar). 'Plate’ simulates the effect of a reverb plate with a quick transient response. 'Room + plate’ is a combination program consisting of reverb plate and room reverberation.” When you know how the clusters are meant to sound, you will interpret the results as realistic. Still, I long for the day when you can sample a real reverberant space in the same way as you can sample a real instrument.
Subjectively the sound of this unit is at the opposite end of the reverb spectrum from the Lexicon PCM 70 that would fit the same rack space. Where, to me, the PCM 70 is warm and dark, even when you try to create a bright clear sound. This unit is sparkling and effervescent, even when you try to dull it down. No, this isn’t the only reverb or multi effects unit you will aspire to own, but I am sure it will prove to be a useful tool in your studio armoury. The modulation effects are good too.
