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. On the rear panel of the Midiverb, there are no real surprises: On power up, the 2N transistor is off the raw supply hasn’t raised up far enough yet to bias the transistor on, through R, R, and the zener divider network.

You can send us a note about this article, or let us know of a problem – midivebr the type from the menu above.

Faulty power supply bypass capacitor, particularly the cap at the analog switch U9. If it containsthe data will be copied to the edit buffer, and not stored to any program location. Be on the watch for user error. In order to see these signals properly on the scope, iiii will be necessary to use an external scope sync use U6, pin 9 as the sync source.


Finally, there are Signal present and Clip LEDs to provide visual indication of input levels and the onset of distortion. These two groups are then sub-divided to each provide six mono and six stereo effects, mannual in intensity – from small alesie big depth, as the manual so iiu puts it. Of course, in practice, being restricted to mono delays means little more than not being able to set up those intensely irritating ping-pong’ effects which seem to crop up on most units these days if you think you’ve just unearthed an underlying prejudice of mine, you’d be right.

The product shows an inappropriate change in performance or does not operate normally, alesie e. Exercise caution when examining the output of comparator U Dispose of used batteries according to the manufacturer’s instruction. This is due to the fact that propagation delay times are not only significant, but inherently part of the design.

Reverb programming is a law mamual diminishing returns, and beyond a certain point you can do little to a program which will ultimately benefit the music. This however Diagram 5 doesn’t last long, as the next high-low transition of the 6MHz clock switches the U16 to the A inputs.

The product under service may employ the use of a replaceable fuse.

As with all Alesis units, the Midiverb III uses an external adaptor, which, it should be noted, provides an AC output as opposed to the DC supplied by almost every other make of equipment – so you can’t interchange adaptors.

Accidentally shorting pins 7, and 8 together manhal instantly result in a dead ASIC. If the product is not used for any significant period of time, the product’s AC power supply cord should be unplugged from the AC outlet.

Actually, given the multiple effects of which each of these units is capable, it is perhaps a little odd that Alesis should have stuck with the verb suffix in the naming of their products. Current program number If the logic seems a bit confusing at midivern, it helps to remember that many of the target signals are active low.


Without ever getting too bizarre, the programs are imaginative and cleverly conceived. It achieves this status by virtue of being programmable – which the Midiverb II is not – but having fewer effects and a slightly less impressive spec than the Quadraverb. Any MIDI data received within milliseconds of the completion of this command may be ignored.

A The arrowhead symbol on a lightning flash inside a triangle is intended to alert the user to the presence of un-insulated “dangerous voltage” within the enclosed product which may be of sufficient magnitude to constitute a risk of electric shock to persons. On the next cycle, the reverse will occur. And don’t forget, the judicious application of a little high frequency roll-off courtesy of the EQ section can provide extra interest in terms of sound colouration should it be required.

Smooth, with none of the tendency toward “ringiness” which mars a lot of reverb programs, it moves from small, live rooms to huge empty halls with consummate ease.

We believe that most, if not all of the original boards that went out have been retrofitted, so their occurance in field should be extremely rare.

These should be affixed to the main PCB we recomend using hot glue. Diagram 5 shows the basic timing of these events. As with reverb, the first edit parameter in the chorus section allows you to choose the algorithm which forms the basis of each program. Note that all access to the SRAM from the is memory mapped see section zlesis.

If the address is memory map decoded by U17 to indicate access to the SRAM, it sets up a chain of events.
