Dave Smith announces Mopho SE analogue keyboard synth

A Mopho with a 44-note keyboard

DSI Mopho SE

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.
