Whether you decide midivetb do it this way depends very much on what it is you need to input, but I found myself using the keypad more and more after getting impatient waiting for the increment button to step from program 6 to program 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.

Next article in this issue Patchwork. If the logic seems a bit confusing at first, it helps to remember that many of alesiw target signals are active low. Alesis shall have the right to refuse to sell or otherwise transfer repair parts or materials to you in its sole discretion. 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.

There are three states of operation. Control over delay consists of two straightforward parameters for adjusting Delay Time and Regeneration feedback – which, when you think about it, is really all you need.

Timing is so critical throughout this circuit that parts that are even slightly out of spec will cause failures. IN Manuql RUSH to condemn the system by which we are constantly entreated to upgrade in favour of “this year’s model”, few of us, I suspect, ever spare a thought for the hapless designer whose job it is to see that we surrender to our acquisitiveness and reach for the cheque book or credit card.


This reduces any audio pop during the attack portion of the input signal, and allows for a faster response to small signals. For example, in some configurations the chorus effect is connected directly to the output whilst in others it is applied to the input of the reverb or delay effects.

The added capabilities of an 80C31 micro controller allow for user manipulation and storage of algorithm parameters, as well as effects such as chorus, and flange, that require real-time manipulation of algorithms.

When describing the Midiverb III as being stereo as I did earlierI jidiverb have given the impression that this applied to the delay section too, which it doesn’t.

For any other service required, the product should be taken to an authorized service center as described in the operating instructions. Replace with only the same type or equivalent type recommended by the equipment manufacturer. Without ever getting too bizarre, the programs are imaginative and cleverly conceived.

Bytes through are as follows: Finally, there are Signal present and Clip LEDs to provide visual indication of input levels and the onset of distortion. midivefb

MidiVerb III Manual

Certainly, this new level of 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. 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. Use extra care to follow the warnings written on the product itself and in the operating instructions.

Incidentally, all mapping functions are global and cannot be stored with individual programs. When A15 address’s most significant bit is active, the 3 to 8 line demux U35 is used to decode several other significant address lines, and send a strobe to the clock input of one of these latches.

The user should only attempt the limited service or upkeep specifically described in the operating instructions for the user.

Problems with this device range from distorted audio, to no display, or aless complete system lockup. And despite its inherent limitations the delay section acquits itself too – even below the ms mark, you can coax enough slapback echo and ADT effects out of it to make it earn its keep.

All things considered, I think using the new sockets and sticking to the right power adaptor is the best approach. Nigel Lord checks the latest incarnation of Alesis’ standard-setting reverb.

Whatever the reason, the user as is so often the case with mass-market equipmenthas come out on top, and with the current crop of machines offering three or four simultaneous bit stereo effects at about the same price you’d have paid for a unit with three or four different 8-bit reverb patches a few years ago, there seems little for us to complain about.

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. Memory mapped input works much the same.
