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.

Comments about Dave Smith Instruments Mopho x4 Synthesizer Keyboard:
I can't believe no one has commented on this yet! All I can say is if you rely solely on the multitude of poor demos scattered on youtube, you will never be able to appreciate this synth. Also don't rely on the presets. While some of them are decent, the real magic is getting in there and turning knobs for yourself. I've used VA synths before so the interface is pretty familiar to me and easy to use. The sounds, however, have a certain aggression and warmth that push forward a bit more than any of my previous synths. Despite having only one selectable 2/4 pole lowpass filter, the modulation options overwhelm. I'm getting lovely synth bass with those beautiful pings on the release, buzzy strings, and a cornucopia of those classic synths sounds that all of us 80's enthusiasts try to mimic. Vince Clarke even expresses fondness for the mopho line and that's a man who knows synthesizers!
I very much appreciate the build quality of this product. The knobs have a solid but slightly rubbery grip. The semi-weighted keybed has a nice spring without being too firm and doesn't give that horrible plasticky, clacking sound you get with cheap keyboards. In fact I'd have to say that this probably one the better ones I've played in a long time. My only gripe, and this is minor, is I wish the buttons were rubberized or otherwise not so plastic feeling.
I always wanted a real analog but could never justify some of the over-hyped collector prices the older gear commands. This is a nice balance of all the charm you get from an analog, but also has all the modern technologies like aftertouch, velocity sensitivity, and usb midi. I'll be holding on to this one for a long time!
