Frequently bought together
Key Info
The Mopho x4 is the newest addition to DSI's revered line of analog subtractive synthesizers. 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 the Mopho x4's 4 voices is composed of 2 analog oscillators, 2 sub octave generators, selectable 2- or 4-pole famed Curtis low-pass filter, 3 x 5-stage envelope generators, 4 x 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.
FM the filter to create metallic bell-like sounds and use the feedback path to add subtle or destructive harmonic content to your sound. The Mopho x4's 100% analog signal path is powerful, monstrous, and sonically dynamic.
The 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 the Mopho x4's polyphony using it's poly chain port. The Mopho, the Tetra, and the Prophet '08 can all be connected to the x4 to increase its voice count. You can poly chain up to 3 x Tetras with the Mopho x4 to create a 16 voice analog super synth.
Designed and manufactured in San Francisco, the Mopho x4 has the high quality sound and build for which DSI is renowned. From its feature packed analog voices and unmatched sonic versatility to its refined design and engaging interface, you won't find a polyphonic analog synthesizer like this anywhere else.
