Alesis Microverb III
MICROVERB III has six different general reverb types, all of which simulate a different space orproduce a different effect. They are:
The room programs (Small, Medium, and Large) not only simulate rooms of varioussizes, but rooms with different surface material as well. A room with soft surfaces suchas carpet will produce a reverberant sound with much less high end (warm) than a roomwith hard surfaces (bright). See your program chart for details about specific programs.Rooms can be used for drums, backing vocals, or just about anything that you wish togive a feeling of space in your mix.
Much larger than rooms, halls are characterized by their high ceilings, irregular shapes,and general density of reflections. Due to their size and density, they work well for long,sustaining sounds like keyboard string pads, vocals, horns, etc.
The plate programs simulate an artificial reverb device known as a plate reverb. Largeand heavy, a plate was a 6 foot by 4 foot piece of steel plate (hence the name) with asmall speaker strategically placed on one end and either 1 or 2 transducers placed onthe other end to pick up the sounds reverberating through the steel. Because it is anelectro-mechanical device, a plate must be isolated from outside vibration and noise andconstantly tuned to maintain the integrity of the reverb sound. In the early days ofrecording, plates were extremely popular because they were one of the only ways to addany sort of artificial ambience to a recording. Plates have become quite popular overthe years, especially on vocals and snare drums.
The chamber programs simulate another way that studios produce artificialreverberation, utilizing a device known as an acoustic chamber. The chamber is asealed, tiled room with a speaker at one end and a microphone at the other. Chambersare not seen much these days since they are difficult to build and take up a great dealof expensive real estate. Chambers are useful on all sorts of instruments, from drumsto guitars to vocals to horns.
Gated reverb is a very popular effect on drums first found on English records in the early1980's. The MICROVERB III's gate programs simulate applying a noise gate (a devicethat automatically decreases or cuts off the volume once a signal falls below a certainlevel) across the output of the reverb causing the initial attack of the reverb to sound verybig, but the tail of the reverb to be cut off very quickly. This effect works great for moderndrums, percussion, and any quickly repeating, transient instrument.
The reverse programs are inverted reverbs in which the volume envelope has beenreversed. This means that the signal begins softly but grows louder until it is cut off,rather than loud to soft as in the gate programs. Reverse reverbs are used on manydifferent kinds of instruments as a special effect.
The MICROVERB III's variety of digital delay programs can be used on all types ofinstruments to enhance sound in a variety of ways. Very short delays (20-95ms) can beused to thicken or double vocals or lead instruments. Medium, long, and regenerateddelays can be used to enhance an instrument or even create a whole new type ofmusical sound. Since the delay programs on the MICROVERB III's program chart havebeen timed out in note values at specific tempos, shown in Beats Per Minute, (forexample, 110ms = 1/16 note @ 136 BPM) drums or guitars can be made to repeat intime with the beat of your song. (One example of this is U2's The Edge, who has maderhythmically delayed guitar a trademark sound).
Multitap delays can be best defined as a number of single delay lines with independentpanning and regeneration designed to work with one another to create a composite,spacious effect. This is ideal for getting "space" into horn stabs or background vocalswithout the decay tail of a reverb. Other creative examples of multitap delays can befound on Def Leppard's "Hysteria" LP.
