Stereo. Connect two mono cords to the [LEFT/CH.1] & [RIGHT/CH.2] INPUTS of the MidiVerb 4 from a stereo source , and two mono cords from the OUTPUTS of the MidiVerb 4 to a stereo amplification system or two mixer inputs.
-
Page 9: Setting Levels
As a good rule of thumb, it is always best to set both input and output level controls at 3/4 or 75% of full. This will decrease the possibility of overload distortion and keep the amount of background noise to a minimum.
-
Page 10: What’s In The Display
Your First Session with the MIDIVerb 4 – Chapter 1 What’s in the Display? When the MidiVerb 4 is first turned on, the display will look something like this: The MidiVerb 4’s display is divided into 5 sections: Program Number . MidiVerb 4 Programs are numbered from 00 to 127.
-
Page 11: Auditioning Internal Programs
To instantly switch between the Preset and User banks, press the [PROG] button. Each time you press the [PROG] button, the MidiVerb 4 will toggle back and forth between the Preset and User banks. The display will indicate this by reading either “PRESET”…

-
Page 14: Adjusting Effects Mix Levels
The Mix parameter’s range is 000-100å. Dry Defeat When connecting the MidiVerb 4 to a mixing console’s aux sends and returns, it is generally desirable to remove the direct (dry) signal from the outputs of the MidiVerb 4 so that its output signal contains only the effected (wet) signal. The dry signal may then be combined at the mixing console with the returning wet signal.
-
Page 15: Comparing An Edited Program To Its Original Settings
Chapter 1 – Your First Session with the MIDIVerb 4 Comparing an Edited Program to its Original Settings The left side of the display always indicates the currently selected Program. If the [PROG] button is pressed once, the currently selected Program’s name and the Configuration being used both appear in the upper part of the display.
-
Page 16: Storing Edited Programs
Program from memory before storing the edited Program, your changes will be lost forever. Although the MidiVerb 4 has two banks (Preset and User), you can only store Programs in the User bank. To store an edited Program: Press [STORE].
-
Page 17: Bypassing Effects
Bypassing Effects At any time you can bypass the effects, thereby allowing the direct signal to pass through the MidiVerb 4 unchanged. This can be done in two ways: • by simultaneously pressing both the [PROG] and [UTIL] buttons on the front panel;…
-
Page 18: Connections
ONNECTIONS AC Power Hookup The MidiVerb 4 comes with a power adapter suitable for the voltage of the country it is shipped to (either 110 or 220V, 50 or 60 Hz). With the MidiVerb 4 off, plug the small end of the power adapter cord into MidiVerb 4’s [POWER] socket and the male (plug) end into a source of AC power.
-
Page 19: Typical Applications
Alternatively, you could use the inserts on your mixer to “patch in” only the left or right channel of the MidiVerb 4. If using the effect sends of a mixer, you have the advantage of sending any of the mixer’s input channels to the MidiVerb 4’s input(s), and have control over the level of each channel being sent.
-
Page 20
• Stereo. Connect two mono cords to the [LEFT/CH.1] and [RIGHT/CH.2] INPUTS of the MidiVerb 4 from a stereo source , and two other mono cords from the [LEFT/CH.1] and [RIGHT/CH.2] OUTPUTS of the MidiVerb 4 to a stereo amplification system or two mixer inputs. -
Page 21: Using The Aux Sends
(headphone) mix, and individual, post-fader effect sends. Typically, if a mixer has more than two sends per channel (4, 6 or 8, perhaps), the first two sends are reserved for the cue sends, while the remaining sends are used to feed effects, such as the MidiVerb 4.
-
Page 22
Connections – Chapter 2 Mono In — Stereo Out. If you only want to feed the MidiVerb 4 a mono input, but wish to connect both of its outputs back to the mixer, you will need three 1/4″ audio cables. Connect a mono cord from an effect send to the [LEFT/CH.1] input of the MidiVerb 4, another mono cord from the [LEFT/CH.1] output of the MidiVerb 4 to an… -
Page 23: Using Inserts
If you do not hear any audio after making these connections, swap the input and output cables at the MidiVerb 4, as these may be wired backwards. If the cable is color-coded, usually the red jack represents the send (which connects to the MidiVerb 4’s input) and black is the return (which connects to the output).
-
Page 24: Using Main Outputs
Stereo. In the case where a stereo instrument (such as a keyboard or sampler) is con- nected to two separate channels of a mixing console, you will need two 1/4″ TRS cables, one for each channel. The connection is made in a similar fashion as described above.
-
Page 25: Avoiding Ground Loops
In some cases, a “star grounding” scheme must be used, with the mixer at the center of the star providing the shield ground on telescoping shields, which do NOT connect to the chassis ground of other equipment in the system. MidiVerb 4 Reference Manual…
-
Page 26: Midi
Note: It is not necessary to follow step 2 if you intend to only send information to the MidiVerb 4, and do not need to receive information back from it. Example: If you only want to be able to recall Programs using MIDI program change messages, there is no need to connect a cable to the MidiVerb 4’s [OUT/THRU] connector.
-
Page 27
Any momentary single-pole/single-throw footswitch, normally open or normally closed, will work for the three footswitch functions. This should be plugged in prior to power-up so that the MidiVerb 4 can configure itself for the type of footswitch being used. Advance. When the footswitch mode is set to the Advance function, each time the footswitch is pressed the MidiVerb 4 will advance to the next Program number. -
Page 28: Overview Of Effects
A Configuration is an arrangement of one or more effects. Each of the 256 internal Programs in the MidiVerb 4 use one Configuration. There are 32 different Configurations available, each of which fall into one of four categories. The four types of Configurations are: Single, Double, Dual Mono and Multi Chain.
-
Page 29: Double
Note: If Cascade mode is turned on, the [RIGHT/CH. 2] input will be disabled for all Dual Mono Configurations. This is because the channel 2 effect is being fed the output of the channel 1 effect. MidiVerb 4 Reference Manual…

-
Page 31: Reverb Effects
Plate Reverb This is a simulation of a classic echo plate, a 4′ by 8′ suspended sheet of metal with transducers at either end used to produce reverb. Popular in the 1970’s, it still prized for its transparent sound, particularly on vocals and guitars. This algorithm uses the most processing available for a truly realistic reverb plate simulation.
-
Page 32: Reverb Parameters
Overview of Effects – Chapter 3 Reverb Parameters Most of the reverb effects in the MidiVerb 4 operate under the same set of control parameters, which are listed and described in this section. However, reverbs which use more processing power (i.e. the Single Configuration reverbs) provide more parameters which take advantage of their extra processing power;…
-
Page 33: Frequency Damping — Low & High
Gate. This can be set between 10 and 500 ms, and controls both the hold and release times of the gate effect. Alternatively, the Gate parameter can be set to “OFF” when you do not wish to use the gating effect. MidiVerb 4 Reference Manual…
-
Page 34: Delay Effects
An additional parameter, called Note, is used to determine what beat value your tempo represents. For example, if you set the note to 4, then you can set the tempo using quarter-note beats to establish delay time. If instead you set the Note to 4t, the same delay tempo setting will play faster because it is simulating quarter-note triplets in relation to the selected tempo.
-
Page 35: Synchronizing To Midi Clock
The Note parameter determines what note value the MidiVerb 4 should synchronize to. For example, if you set the Note value to 4, then you can synchronize to the quarter-note beats of the incoming MIDI clock. If instead you set the Note value to 8t, you can synchronize to eighth-note triplets relative to the incoming MIDI clock signal.
-

“rhythm” of the phasing. Chorus This is a mono, less processor-intensive version of the Stereo Chorus effect, used in the Multi Chain Configurations Chorus->Realroom and Chorus->Dly->Room, the Double Configuration Realroom+Chorus, and the Dual Mono Configurations Chorus:Chorus and Chorus:Delay. MidiVerb 4 Reference Manual…
-
Page 37: Stereo Flange
The “Thru0” parameter found in the MidiVerb 4’s flanging effects lets you create the appearance of the effected signal passing through the zero point. It does this by actually delaying the uneffected signal by as mush as 12 milliseconds (an amount virtually undetectable to the human ear).
-
Page 38: Flange
The Auto Pan effect alternates the loudness of the signal in opposite channels at a definable rate. Low and high frequency cutting is available, and (like the flange effects) can be triggered by the input signal (either the left or right input, or both). MidiVerb 4 Reference Manual…
-
Page 39
(how long the Auto Pan will wait before it can be retriggered). The Direction parameter can be set to alternate; that is, the Auto Pan will change its start direction with each succesive trigger. MidiVerb 4 Reference Manual… -
Page 40: Editing Programs
A Configuration is made up of one or more effects. Each of the internal Programs of the MidiVerb 4 use one Configuration. When you want to create your own Program, the first thing you must decide is which Configuration you wish to use. Then you need to locate a Program that already uses this Configuration.
-
Page 41: Editing Effect Parameters
Chapter 4 – Editing Programs Editing Effect Parameters Editing Programs is only possible while in Program mode. This means that the [PROG] button must be lit. If the [PROG] button is not lit, press it now. From Program mode, you can edit the currently selected Program by pressing either [EDIT/PAGE] or any of the [A], [B], [C] or [D] buttons.

4 ignores program change messages. When set to on, incoming MIDI program change messages received on the same channel the MidiVerb 4 is set to will recall the same numbered User Program. When set to table, the MidiVerb 4 will use the Program Change Table (see below) to remap incoming program change messages.
-
Page 48: Store Button
There are 128 different possible MIDI program change messages (000 – 127). However, the MidiVerb 4 has 256 Programs to choose from. Therefore, the Program Table allows us to choose which of the 256 Programs will be recalled when certain program change numbers are received.
