From Lexicon:

The MPX 110 is a true stereo, dual-channel processor with 24-bit internal processing, analog-to-digital conversion, and digital-to-analog conversion. It offers 240 presets with classic Lexicon reverbs, including Plate, Chamber, Ambience, Tremolo, Rotary, Chorus, Flange, Pitch, Detune, 5.7 second Delay, Echo, and Inverse. Dual-channel processing creates two independent effects in combinations such as Dual Stereo (Parallel), Cascade, Mono Split, and Dual Mono. The front panel Adjust knob allows instant manipulation of critical preset parameters, and the Effects Lvl/Bal knob controls effect level in SINGLE programs or effect balance in DUAL programs. All programs can be selected with the PROGRAM and VARIATION knobs. The PROGRAM knob selects SINGLE, DUAL, or User programs, while the VARIATION knob selects among 16 program variations. Tap Tempo simplifies the once-complicated process of matching delay times and modulation rates between tempo-based presets and other music. Tempo-controlled delays and modulation rates lock to Tap or MIDI clock. In addition, Tap can be controlled using audio input, a dual footswitch, the front panel Tap button, or an external MIDI controller using MIDI Continuous Controller or Program Change messages. The MPX 110 features Learn Mode, a powerful editing tool that allows MIDI patching of five front panel controls. Standard Continuous Controller and Program Change messages provide complete control over Bypass, Effects Lvl/Bal, Mix, Tap, and even Adjust.
