Lexicon MPX1 Stereo multi-effects processor The Lexicon MPX1 is a professional multi-effects processor renowned for bringing Lexicon's signature, high-quality stereo reverb to a more accessible price point. It utilizes a unique dual-processor architecture to provide uncompromised reverb alongside a wide array of other effects. Key Features and Specifications The Lexicon MPX1 is a 1U rack-mount unit designed for both studio and live applications, featuring comprehensive connectivity and deep programming capabilities. Dual Processing Architecture: Employs a dedicated proprietary Lexichip for world-class stereo reverb and a separate fast-math DSP for other effects, ensuring high performance without compromise. Effects Arsenal: Offers a total of 56 effects, including chamber, hall, plate, gate, and ambience reverbs, as well as delay, chorus, flanger, phaser, EQ, pitch shifting, and overdrive. Connectivity: Features balanced analog I/O (1/4" and XLR), S/PDIF digital I/O at 44.1 kHz, a full suite of MIDI In, Out, and Thru sockets, and dedicated inputs for a footswitch and foot controller pedal. User Interface: Includes an interactive front panel with both an alphanumeric display and a large numeric indicator, dedicated effect block buttons, and a built-in help system (press and hold any button for an explanation). Dynamic Control: Offers extensive modulation capabilities, including two LFOs, an arpeggiator, envelope followers, and the "Dynamic MIDI" feature, allowing parameters to be controlled in real-time via various sources. Memory: Contains 200 preset programs and 50 user-programmable memory locations, which can be organized using a database sorting function. Tap Tempo/A/B Morphing: Front panel "Tap" and "A/B" buttons allow for real-time control over tempo-related parameters and morphing between different parameter settings or effect variations.
