Dave Smith Instruments Mopho

Dave Smith Instruments Mopho Image

Dave Smith Instruments is back with another excellent and affordable analog monophonic synthesizer. The Mopho is a single voice from the mighty Prophet ’08 with the addition of one sub-oscillator per DCO. It offers a stereo output and an audio input for processing external sound through its fantastic Curtis lowpass filter. The Mopho's 2+2 oscillators, fully analog signal path, extensive modulation capabilities, and characteristic DSI lowpass filter makes big analog sound available at an astonishingly low price!

The desktop module version includes dedicated knobs (detented encoders) for pitch, volume, program selection, filter, and basic envelope controls as well as four knobs that can be assigned to any other parameters the user chooses. The interface is somewhat limited, but easy to learn and navigate. To overcome this limitation, there is a free Mac/Win software editor included, and there are a few third-party software editors available as well. Additional features include four LFOs, a gated 16-step sequencer, three ADSR envelope generators and an arpeggiator. There is also a "Push-It" button which auditions patches, can step through a sequence or function as a tap-tempo button.

The keyboard version adds a USB interface, as well as a 32 key (2.5 octave) semi-weighted keyboard with velocity and aftertouch. With much more front panel real estate available, far more parameters are immediately accessible via 25 knobs as opposed to the desktop version's 10. Pitch Bend & Mod Wheels and classic wooden end panels are nice additions too.

Both versions include a prorietary Poly Chain socket which allows you to connect and control other Dave Smith Instruments synthesizers for expanded polyphony and a much bigger sound. This works particularly well with the Prophet '08, and the Tetra.

The Mopho is an excellent choice for anyone looking for large, aggressive analog sound combined with extreme flexibility at a very low price. It's tempting to make the Pro-One comparison, but it's much more accurate to think of the Mopho as a descendant rather than a reproduction. It shares the same spirit and function, but has a soul and personality that is all its own.

I love the Mopho keyboard. I had absolutely no midi issues with it, I use it also as controller keyboard with pitch/bend/aftertouch/velocity for poyhonic synths. Works brilliant. The tweaking via menu is not optimal, but offers great possibilities. Arpeggio/Sequencer has no Midi out, that's the only Minus. For me, it is not a problem. The OSCs and Curtis Filter sounding great.

Not a terrible synth but I sold mine. Initially I was impressed but in the end I found it a little dull. Also small things really bothered me - like having the Osc Sync function hidden deep in a menu! Crazy. I also found the modulation section unnecessarily complicated. There was also an issue with the MIDI signals sent from the keyboard which sadly made it useless as a controller.

On the other hand, I have retained my DSI Evolver. It can do everything the Mopho can do and a whole lot more. My favorite analog so far. And I've owned a few!

DSI rocks. The analog revolution is in full swing. Bring on the polysynths now!

I love my Mopho KB! It's analog regardless of the DCOs. Analog is has always been what makes a synth. I hope this paves the way for synth companies to understand that analog is the way to go. I'm sick of this analog modeling garbage (Roland, Korg...they are going in the wrong direction!)--Lazy! Get the Mopho Keyboard if you want to tell the market that we demand that a synth be analog. I'm happy that DSI gets it... I mean, just look at eBay--People are willing to pay high prices for analog and it's not hard to see that. Thanks to Dave and his team for understanding the need for analog.

There is a hold function for arpeggiated chords, though it is a little clumsy. You have to hold the hold button down for a second until it blinks once. Then whatever notes you play will be arpeggiated in the pattern you have set. The drawback is that once the hold button has been set you have to release it and press it down again to switch to a different chord. Otherwise any other notes you play will be added to the existing arpeggio.
