Processed signal is mixed with the ‘dry’ one in analog after the conversion MIX button. Digital reverb is an effect that is used in just about every recording made.


Although the pot for adjustment is easily accessible I have no idea how to do this procedure as it would require mkdiverb values 7FFF and down to the DAC but only the DSP can do this so you’d have to grab direct control over the DSP 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’. DSP handles one sample at a time. Actually only bytes required to store a DSP program are addressable.

None that I know of worth checking: And came back with nothing so I had to open the box and take a closer look. This results in 15KHz bandwidth for the processed audio signal after Digital-to-Analog conversion.


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. When MidiVerb II is switched on the first program in the mapping table is read and activated. CD, in comparison, uses a meager 16 bits. Trimpot for MSB error adjustment procedure.

SynthMania PlanetZero lists and forums: Here are my findings based on observations, measurements and some speculation about what’s going on in MidiVerb II. Automatically a steep price came to mind. Further information on the Alesis MidiVerb 4 reverb and effects processor.

In addition to reverb, the Alesis Midiverb 4 also provides chorus, flange, delay and pitch changing effects. Alesis Midiverb 4 Review – Record-Producer.

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. Analog-to-Digital conversion is managed by method of ‘successive approximation’. Datasheets for more ‘interesting’ chips, as well as amnual user manual and program chart can be downloaded below.

All comments, clarifications, corrections, rectifications, amendments and revisions are warmly welcome here. Midiverb II Program Guide. The quality of the digital audio processing imdiverb excellent with bit conversion and bit internal processing. The instruction sequence DSP program manula of bytes is continuously fetched in loop at 8 MHz clock speed from Program store SRAM so that the whole program gets executed during one sample cycle 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.

There is no dedicated ADC device involved. MidiVerb II is an amazing machine – in the era of cheap silicon and huge memory chips it’s still being used widely after 20 years or so in existence. In comparison to some units that can only produce one effect at a time and remember that kanual always need reverbthis unit allows up to three simultaneous multieffects.

This memory consisting of memory locations is only visible to the DSP. I tried to google for schematics, service manual and a datasheet for the DSP chip. I give this product two thumbs up.

There’s not much ‘analog’ in this box, I must admit, but I was just wondering why it sounds so much better than the later MidiVerb III. The most impressive thing to me was the all of the different sounds and clarity.

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 midkverb the input signal level and concentrate on the sound you are hearing.
