Dave Smith announces Mopho SE analogue keyboard synth

The Mopho SE's black case is more reminiscent of the Mopho X4 than the standard Mopho.

Small and affordable analogue monosynths are all very well, but how about if you want one that has a decent-sized keyboard that can be used for more than just playing simple bass and lead lines?

Step forward Dave Smith Instruments' Mopho SE, a new version of the Mopho that rocks a 44-note keyboard. This is velocity-sensitive and supports aftertouch.

The synth is powered by the existing Mopho engine, which comprises two analogue oscillators, two sub octave generators, a selectable 2- or 4-pole famed Curtis low-pass filter, three 5-stage envelope generators, four LFOs, a re-latchable arpeggiator, and a 16x4 step sequencer. There are 20 modulation sources and close to 50 destinations.

More specs below. At $949 this isn't the most affordable hardware synth on the market, but if you want a decent keyboard built into your instrument rather than having to plug a controller in, it could be the perfect choice.
