      Dave Smith Instruments Mopho x4 Synthesizer Keyboard (H88625)
Availability:  


Full-sized 44-note analog subtractive synthesizer

Building upon the same award winning voice architecture of the Mopho and Mopho Keyboard, the Mopho x4 boasts huge sound and 4 voice polyphony in an ideally sized, portable, and elegantly designed package. Use it to create huge unison basses, creamy leads, maniacal sequences, and ethereal pads.

Each of Mopho x4's four voices is composed of two analog oscillators, two sub octave generators, selectable 2- or 4-pole famed Curtis low-pass filter, three 5-stage envelope generators, four LFOs, a relatchable arpeggiator, and a 16 x 4 step sequencer. Its voice also comes packed with 20 modulation sources and almost 50 destinations. You can FM the filter to create metallic bell-like sounds and use the feedback path to add subtle or destructive harmonic content to your sound. Mopho x4's 100% analog signal path is powerful, monstrous, and sonically dynamic.

Work less, play more
Mopho x4 is intuitive and inviting. Every parameter is fully programmable and editable from the front panel. The controls are logically laid out, lending themselves to 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 sturdy full-sized pitch and mod wheels are freely assignable and sport smooth reliable action.

Expand your sonic horizon
Expand Mopho x4's polyphony using it's Poly Chain port. Mopho, Tetra, and Prophet '08 can all be connected to the x4 to increase its voice count. You can Poly Chain up to three Tetras with Mopho x4 to create a 16 voice analog super synth.
