Review by Nigel Lord. Dispose of used batteries according to the manufacturer’s instruction. Some crystals are shock sensitive. This can help prevent many unhappy returns.
So if, like me, you enjoy writing percussion tracks which use delay as an implicit part of the rhythm, you’re likely to find the Midiverb somewhat restricted, particularly on miidiverb tracks. The ROM programs included on the Midiverb III, despite not being described in the accompanying manual are in all ways representative of the sort of results it is capable of producing.
During write cycles of thedata on the data buss is made available to a series of latches U12, U22, and U A few final notes: The latch ensures that data is good when the samples the buss latches the contents of the buss into itself even though the SRAM itself may be busy with the ASIC.
If you are not authorized, please contact Alesis and destroy all copies of this document.
Qualified service personnel should service the unit in certain situations including without limitation when: Replace with only the same type or equivalent type recommended by the equipment manufacturer.
More on this later. Familiarity with the appearance of this signal on a scope, will greatly facilitate troubleshooting audio problems.
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. Later, the circuit was incorporated into the main PC Board. 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.
On a more positive note, the manual contains individual block diagrams for each of the 15 configurations, and lists the various effects possibilities available from each.

As explained earlier, the maximum ms delay is available only in the last two configurations 14 and 15which do not include any reverb effect. Manuwl through are as follows: 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 kidiverb. Some chokes were found to have broken loose during shipping. The product under service may employ the use of a replaceable fuse.

Beyond that, however, I can think of little to criticise. Problems with this device range from distorted audio, to no display, or a complete system lockup. This is quite straightforward in operation apart from its use with gated reverb effects where it is used to determine the length of the gated sound, and on reverse reverb where, for obvious reasons, it has no effect at all.
Most of these early units have been retrofitted with an extra board containing the newer reset circuit.
But then, I don’t suppose Alesis need any marketing lessons from me. Some important control signals are outlined below. The first of the two reverb parameters, Reverb Algorithm, offers you a choice of 20 different reverb types from a list which includes halls, chambers, rooms, plates, reverse and gated effects.
The stereo signal is then sent to a X10 gain stage U1 etc. The product should only be cleaned as the manufacturer recommends.
Of course, it is finished in a rather alesid shade of black as opposed to the electric puce more familiar to our guitarist friends, but I’m sure even they could learn to live with midkverb. Gear in this article: Timing is so critical throughout this circuit that parts that are even slightly out of spec will cause failures.
Adobe flash cs 5.5 free download for mac. There are three states of operation. There’s no doubt that the specifications of the Midiverb III – the latest in Alesis’ range of budget reverbs – would put your average double bucking, tube screaming, electric cry-baby effects pedal to shame: These two groups are then sub-divided to each provide six mono and six stereo effects, varying in intensity – from small to big depth, as the manual so quaintly puts it.
Damage to the Product.
All Trademarks are property of their respective companies. Being designed primarily for use in studio racks, the Midiverb III is a 1U-high, 19″ rack unit with all controls alessis on the front panel.
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. A small piece of electrical tape on the case top, above the choke, or hot glue applied in a thin layer to the top of the choke should alleviate manula situation. From there, the inputs are buffered by U1, and passed through the input potentiometers.
Alesis show us how to cram big spaces into ever smaller boxes!
The Alesis Picoverb is barely any larger than it's own power adaptor, but it is a surprisingly ruggedly built effects box. Rather than skimp on quality, the designers have thrown many of the features we take for granted overboard, retaining 24-bit conversion and good effects algorithms. You get 16 preset effects broken down into hall reverbs (two), room reverbs (three), plates (three), chorus, flange, delay (two) chorus/room (two), voice canceller and rotary speaker. There are Input and Mix knobs, but no level metering or even a clip LED, so you need to set the input level by ear. Stereo inputs and outputs are provided on unbalanced jacks, with the provision to use the left input only for mono-in use.
Though the effects are entirely preset, they sound surprisingly 'right', especially the reverbs, which vary in sensible steps from a very short, ambient room, through some nice-sounding plates and medium rooms well suited to drums and vocals, right up to warm hall sounds. All the reverbs have a dense, smooth decay and just the right amount of character. While they may not have the finesse of high-end studio reverbs, they're a lot better than I've heard from most budget units and generally much better than you'd hear from even one of the better host-powered reverb plug-ins.

The chorus effects are also very strong, with a six-tap chorus effect plus two further chorus/reverb combinations offering slow and faster speeds. The ratio of depth to speed is well chosen in all cases and the Mix control provides some degree of control over intensity, with the effect sounding particularly good on electric guitar. There's also the obligatory flanger with a nice slow, deep sweep and just the right amount of feedback, plus a couple of delay treatments. The first is a short slapback delay, good for those old John Lennon vocal sounds or Rockabilly guitar tracks, while the second is a stereo reverb where one side is delayed by 291ms and the other by 388ms, providing a credible guitar instrumental sound.
At preset 15 we find a vocal eliminator, which removes all mid-range sounds that are panned dead centre. On most tracks, this drops the vocal level by a significant amount, but leaves any reverb or other stereo treatments at their original level. The degree of cancellation is determined by the Mix setting. Naturally there are side-effects to this process, so while you could get away with using treated tracks for casual Karaoke backings, you couldn't use them in any serious recording context.
Finally comes a rotary speaker simulation at a fixed fast speed, which on guitar makes a credible job of replicating the guitar sound from Cream's track 'Badge'. It is also useful for treating pad sounds, organ patches and even vocals.
While the Picoverb offers no user editing other than mix depth, the sound quality is good and the effect presets are well constructed. I was particularly impressed by the reverb and chorus effects, and the only feature I felt shouldn't have been left off was a peak warning LED. Computer users with multi-I/O soundcards could do worse than configure a Picoverb in a send/return loop, and of course the unit is great as a basic project studio effects box — it still offers more flexibility than the original plate reverbs!
For the UK price of a toy, you get very respectable effect quality, although you have to use the presets created for you. Just because the Picoverb is small, cheap and almost trivially simple, don't dismiss it, because it can do a seriously good job.
