Overview

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.

    Comments about Dave Smith Instruments Mopho x4 Synthesizer Keyboard:

    I tried the Minilogue and Gaia. Both are good for their price, especially a used Gaia. Monologue has analog VCO's, the Gaia is a ROMPER. I prefer full size keys, and instead of getting 2 synths, I picked up a used X4 at GC. Although there are limitations (every synth has limitations), the X4 is intuitive to program and essentially has a patch bay of modulation options which are user selectable and can be routed just about everywhere (4x LFO, 4x Mod sources, 3rd envelope, etc). All are easily accessible from the top panel. The nice feature if that when you are editing a parameter, the original value is displayed on the top line. Neither the Minilogue nor Gaia has this feature (you can get this in there Gaia with s $90 editor). Although a lot of people knock the Gaia, is it actually a great sounding synth, easy to program and play. But if you are going to use the editor to see the actual programmed values, you may as well just get a iPad Synth app or Mac app.... Im still 50/50 on a tetra or a minilogue in the future.

    The presets on the X4 do not seem to be built for the sonic quality, but instead to showcase the vast modulation options. Most of the DSI and YT videos are tweaking the parameters, vs playing the keyboard. You have to trust DSI, they have been building synths for 30 years. You really need to dive into all there options to create excellent sounds from this synth, but this is easy to do. The 44 key keyboard is perfect, 61 is too big at times, 37 comes up just a little short. 4 note poly is OK, it actually fits my style so this is not an issue. I believe you can program around all the "limitations" once you figure out the options.

    This is a quality instrument, I was surprised there are no other reviews for this.
