MidiVerb 4

The Alesis MidiVerb 4 reverb and effects processor is a low-cost effects unit that functions according to normal professional practice, and therefore can be seen as an ideal introduction to reverb and effects units.

Digital reverb is an effect that is used in just about every recording made. The quality of the Alesis MidiVerb 4’s reverb is comparable with many reverb units used in professional studios, being described as ‘dense’ and ‘natural’. The quality of the digital audio processing is excellent with 18-bit conversion and 24-bit internal processing. (CD, in comparison, uses a meager 16 bits).

Although not a part of normal professional studio practice, this unit features automatic input level sensing, which means that- if you want – you can pretty much stop worrying about optimizing the input signal level and concentrate on the sound you are hearing.

In addition to reverb, the Alesis Midiverb 4 also provides chorus, flange, delay and pitch changing effects. In comparison to some units that can only produce one effect at a time (and remember that you’ll always need reverb), this unit allows up to three simultaneous multieffects.

User comments

  • “When I first was told about this product about all its features and sounds I was impressed. Automatically a steep price came to mind. I also thought it would be complicated to program the effects. As soon as i got it plugged I noticed how simple it was. If you can program your remote control you can work one of these. The most impressive thing to me was the all of the different sounds and clarity. And if that wasn’t enough you can program them to make more, or just to find the right sound for the right feel.I give this product two thumbs up.”
  • “It really fits my style, I’m playing kinda Satriani stuff, I’ve been playing guitar for 3 years and a half so this is my first rack product (i got tired of those farking little noisy pedals) and I’m happy with it. If it were stolen I definitely would buy another one.”
  • “This is a good unit and allows me to create some very individual sounds, the like of which I have never heard, though I think this is more down to my lack of respect for doing things conventionally. It also has MIDI options (you would never guess from the name), but I don’t use these. There are also many other features on it that I have never and probably will never use, but that’s only because I’m very happy with what it does to my sound.”
