Alesis MidiVerb 4 Digital Effects Processor Details

Alesis MidiVerb 4’s superb reverb and effects algorithms are the direct result of our ten-year mastery of the art and technology of sound. As the world’s leading designer of full custom VLSIs for digital audio, we put our latest and best efforts into this superior signal processor. Alesis MidiVerb 4 boasts an extremely powerful 20 Bit DSP engine that is so advanced it eliminates massive quantities of discrete circuitry and drives its price/performance ratio to a level unrivalled in the music and audio worlds.

Delivering high performance at an affordable price is what made the original MidiVerbs the leading signal processors of their day. Alesis MidiVerb 4 will extend that lineage for a long time to come. “The best part, as with its predecessors, Alesis MidiVerb 4 will take care of all your signal processing needs without damaging your bank account. No matter what the application – instrument, studio, stage – Alesis MidiVerb 4 is clean, quiet, rich and smart. MidiVerb 4 provides great effects processing for a wide variety of applications. Each effect algorithm was carefully designed to offer advantages that average processors may not include.

When it’s time to choose Reverb effects processing for vocals and instruments, Alesis MidiVerb 4 has some great options to choose from. The Concert Hall algorithm offers a superb simulation of a large hall with many reflective surfaces. like a real concert hall, the reverb’s timbre changes as the reflections diminish.

It’s a classic reverb that sounds equally great on vocals as it does on drums, electric and orchestral instruments. MidiVerb 4’s Real Room algorithm offers a simulation of a medium-sized studio recording room. It’s a very rich sound with a smooth decay. Ambience effect simulates a very small room and is useful to thin sounds without dramatically changing their timbral content. “The Plate Reverb effect in Alesis MidiVerb 4 gives you that classic plate reverb sound.

It’s a great effect to use with lead vocals, snare drum, or rhythm guitar. Also, MidiVerb 4 provides a Nonlinear (reverse) reverb effect that’s great to use with drums or other percussive sounds for an excellent backwards tape effect. The best thing about MidiVerb 4’s Reverb effects is that regardless of your application, you’ll be able to fine-tune the effect for your individual need with an extensive list of parameters. Alesis MidiVerb 4 not only offers standard reverb parameters like Decay and Pre-Delay, but also provides advanced parameters that all effect gives you the classic tunnel sound that you came to know and love in your old stomp boxes… without all the unwanted noise and distortion.

MidiVerb 4’s Stereo Pitch Shift effect, as the name implies, allows you to select individual detune amounts for the left and right channels, for harmonisation on guitars, synths and other instruments. ‘The Mono Pitch Shift can also be combined with Delay for some interesting Doppler-type sound effects. MidiVerb 4 also includes an Auto Pan feature which allows you to alternate the loudness in opposite channels. You can define the panning rate, direction and high/low frequency attenuation of your signal. Auto Pan is not only great for all instrumental applications, but also for audio post-production for film and video purposes.

If you ever use organ patches on your keyboard, you’ll appreciate MidiVerb 4’s Lezlie effect. The Lezlie effect simulates the complex timbral changes of a mechanical rotating speaker. “The resulting sound of MidiVerb 4’s advanced DSP engine combined with this advanced pitch algorithm is astounding. Available parameters for this effect include Motor On/Off, Speed (either slow or fast), and High Rotor level, which attenuates the high frequency volume. Alesis MidiVerb 4 is so smart that it even ramps the Leslie effect rather than changing abruptly when you turn it on or off, or when you change rotor speeds, just like a true rotating speaker system.

Each of MidiVerb 4’s 256 programs use one of 32 configurations, or arrangements of effects. Single configurations consist of one effect and utilise complex effect algorithms both in mono and stereo. Double configurations have two mono-in/stereo-out effects linked together. Dual Mono configurations provide one mono-in/mono-out effect for each channel. Plus, Cascade Mode allows you to route the output of the channel one effect into the input of the channel two effect for great sounding multieffects. Inst, Multi Chain configurations provide two or three stereo effects connected in a series.

MidiVerb 4’s MIDI capabilities provide several different functions: recalling programs using MIDI Program Change messages, sending and receiving Sysex (System Exclusive) dumps of individual programs or program banks, and passing information through to another MIDI device. Plus, Alesis MidiVerb 4 allows you to modulate parameters in real time. via MIDI controllers (pedals, mod wheels, etc.). Each configuration offers two carefully chosen parameters that can be modulated via MIDI. In the middle of a performance, you can alter reverb decay, delay feedback, and flange depth among other parameters, making the MidiVerb 4 an extremely versatile processor for every application.

MidiVerb4 has the unique ability to automatically select the proper levels for the inputs bast on the signal you are routing to it. In Other words, you tell the MidiVerb 4 to auto-adjust levels, and then feed it a signal (by playing your guitar or keyboard or playing back tape); MidiVerb 4 does the rest. All you have to do is press the front-panel Input and Output buttons at the same time. Alesis MidiVerb 4 will listen to your signal for five seconds (or as long as you choose, using a standard footswitch pedal to trigger the Auto level Sensing feature). Your input signal will be set to the optimum level to take advantage of Alesis MidiVerb 4’s wide dynamic range.

Have it in the studio right now. Same core as the Alesis Wedge, which I owned prior to this unit. You get a lot for the budget. Mine seems to be an early unit with no MIDI Clock recognition. I’d recommend to aim for a Wedge as a desktop version. Issue I have with the Rack version is that the display, hence it shines bright, is not readable from any angle.
