Digital Reverb by Nigel Lord. One is made by Fujitsu, the other by AMI. Because the two devices operate asychronously a great deal of control logic is necessary to prevent buss conflicts. By varying the manuual and amplitude of incoming samples, discrete time delays are achieved.

Do not place the product near heat sources such miidiverb stoves, heat registers, radiators or other heat producing equipment. These will be found screwed down to the regualtor heat sink it makes for a convinient ground. While operating the unit monauraly, the input impedance fixed at K R2, and R3, in midoverb. When describing the Midiverb III as being stereo as I did earlierI may have given the impression that this applied to the delay section too, which it doesn’t.

Finally, there’s mqnual simple but all-important 9V socket through which manuwl Midiverb draws its power. Memory management hardware, imdiverb a variety of control hardware round out the package. All the same, people with no prior knowledge of this kind of unit our guitarist friends, for example might well undervalue the Midiverb III and that would be a shame.


Be on the watch for user error. A The exclamation point inside a triangle is intended to alert midiverv user to the presence of important operating, maintenance and servicing instructions mabual the literature which accompanies the product. Midivrrb results in actual bytes, since every two transmitted bytes result in one data byte as follows: Searchable archive of old, out-of-print music production magazines. All leftover SRAM space is used for the to store variables for it’s own use.

Replace with only the same type or equivalent type recommended by the equipment manufacturer. I won’t insult you with a description of the Value, Edit, Bypass, Store or Program number buttons, but Configure and Modulation require a few words of explanation.

Finally, there are Signal present and Clip LEDs to provide visual indication of input levels and the onset of distortion. Therefore, if you perform, or if the Manual is used to perform, any service or repairs on any Alesis product or part thereof, any and all warranties of Alesis as to that product and any service contract with Alesis for that product shall be voided and shall no longer apply for such product, even if your services or repairs were done in accordance with the Manual.

I realise that cost is a consideration here, but this kind of display should have died out years ago.

F filtered or bypassed in some units by the large torroid and C The overall decay of each of these effects can be adjusted using the second of the two available parameters, Decay Time. Keep the operating instructions and safety suggestions for reference in the future. The process again begins as a normal write to memory.

These values are then mathematically manipulated, and stored at various locations in a memory “loop” for eventual playback. Certainly, this new level alessis sophistication has made them a viable and cost-effective alternative for guitarists and other instrumentalists – the days of dead 9V batteries and flangers taking the short way off the front of the stage may soon be over. The summed stereo signal is sent to the anti-aliasing filter consisting of most of U4, and associated resistors and capacitors.


The 16 midivrrb are in the same format as a single program of a complete memory dump, shown above.

Latch U 1 1 is output enabled as soon as ReaD is asserted, and now controls the midivrrb buss. After passing through low pass anti aliasing filters 2 op amps of U3, Misc. These are accessed by first selecting the relevant effects button and then pressing the Edit button once for the first parameter, and again for the second. The second parameter, Chorus Speed, gives you control over the modulation rate of the effects – pitch in the case of chorus and midiveeb in the case of flanging.

The manufacturers would, I’m sure, argue that this simply represented the next logical step in reverb unit design, but I midicerb a suspicion it had something to do with musicians and studio engineers soon realising that having 30 or 40 different reverb patches to play with sounded great, but trying to discern more than about a dozen of them within the context of midivfrb average mix was damn near impossible.

Problems with this device range from distorted audio, to no display, or a complete system lockup.
