Reflection sound which is usually sacrificed in commercial reverb products in order to reduce costs In practice the Early Reflection sound means the very first reverberated sound that bounces back from walls floors and ceilings of concert halls The entire reverb sound quality depends on this Early Reflection sound and how closely it can resemble the real echo The H F A is an algorithm that enables the effect unit to reproduce a clear and natural Early Reflection sound by applying an ideal harmonic feedback to each delay module H D L P Hi Density Logarithmic Processing The reverb sounds consist of lots of small delay elements combined in a complex way which are produced by many delay modules inside the effect unit In order to obtain smooth and comfortable reverb sounds it is very important to efficiently organize the relationship between each delay module and minimize negative mutual interference The H D L P is a technology which applies efficient logarithmic processing to each delay module so that they can work in the most efficient way in order to eliminate harmful reverb elements and roughness This makes it possible to establish high density and transparent sounds Before operating the EFFECT MODE let s briefly discuss the Reverb Delay Chorus and Flanger effect functions which are integrated in the VM04 Reverb The Reverb effect consists of various reflection echo sounds mixed together Just
