Behringer's Modulizer Pro is a rather curious device, because although it's clearly aimed at the budget end of the market, it comes with both balanced jack and XLR inputs and outputs. Essentially it is a stereoin, stereoout signal processor designed to create mainly modulationstyle effects. Only one effect algorithm at a time may be used, and there aren't any reverbs, but then what sets this unit apart from most multieffects units is the number of what can best be described as soundmangling effects, such as ring modulators, simulated tube distortion, envelope filters and so on.
Though inexpensive, the Modulizer Pro is a goodlooking unit, solidly built and with a mains power inlet rather than the more usual external supply. It has the full set of MIDI In, Out and Thru sockets for patch changing and realtime parameter control, and the audio ins and outs may be switched for 10dBv or +4dBu operation.
All the effects are based on one of the 24 available effect algorithms, all of which are listed on the front panel, where the user can access the effect type, a Variation parameter, four further individual parameters specific to the algorithm and a pair of high and lowcut filters. There's a separate button to select the algorithm on which the effect is based and there's a frontpanel bypass button. All the buttons have integral LEDs. Though this is the limit of the user control, the same adjustments may be made in real time over MIDI, and if patches are changed via MIDI, you avoid a delay of a second or two that occurs when you change patches from the front panel. A single rotary control takes care of parameter adjustment, where both parameter values and patch numbers are represented as simple numbers in the 7segment numeric display there's no text facility. In addition to the internal modulation LFO, there's a mode where the modulation rate can be controlled directly using the parameter dial or a MIDI input rather than the internal LFO.
