Sequential Mopho x4 overview

  • 1Description

The Mopho x4 44-Key Polyphonic Analog Synthesizer from Dave Smith Instruments is a 4-voice polyphonic analog synthesizer with 44 semi-weighted, velocity sensitive keys with aftertouch. Each voice is powered by 2 oscillators that offer a selection between sawtooth, triangle, saw/triangle, and variable pulse width square wave waveforms. In additional to dual oscillators, each voice also has two sub-octave generators designed for creating sub-bass tones. You can alter and shape the voices through their Curtis low-pass filter, 4 LFOs, and 3 envelope generators.

Further sonic sculpting can be done through the voice-independent 16x4 gated step sequencer and arpeggiator. The Mopho x4 offers a variety of connectivity, including a 5-pin DIN MIDI input, output/thru, and poly chain connection that allows you to connect the Mopho x4 to a Mopho, Tetra, or Prophet '08 synth for an increased voice count. While it features a variety of knobs for hands-on control, the free downloadable software editor for Mac and PC allows you to use your computer to edit sounds on the Mopho x4 via its USB port.

Polyphonic Mopho
Building upon the same voice architecture of the Mopho and Mopho Keyboard, the Mopho x4 boasts 4-voice polyphony in a portable package. Use it to create unison basses, leads, sequences, and ethereal pads
4 Times the Voice
Each of Mopho x4's four voices is composed of two analog oscillators, two sub octave generators, a selectable 2- or 4-pole Curtis low-pass filter, three 5-stage envelope generators, four LFOs, a re-latchable arpeggiator, and a 16 x 4 step sequencer. Its voice also comes packed with 20 modulation sources and almost 50 destinations.
Work Less, Play More
Every parameter is fully programmable and editable from the front panel. The controls are designed for quick access so you can tweak knobs without missing a beat

The x4's full-sized, 44-note semi-weighted keyboard has aftertouch and velocity sensitivity. The full-sized pitch and mod wheels are freely assignable
