Monophonic analog synths are all the rage these days. Unfortunately, so too are tiny keyboards or few octaves.

The Mopho is what you’ve been asking for. It has 44 keys, semi-weighted, with not only velocity but aftertouch, too. That means you don’t need to relegate your monosynth to tiny basslines and carry another controller.

You also get a metal enclosure, now with artwork screen-printed on directly, plus the soft-touch knobs from the Prophet 12.

And one killer feature, for people who hate yellow, or fear school buses or bees: it’s a tasteful gray color, not the shade of a canary.

MAP: US$949, shipping end of October.

Of course, you could still get a Mopho module (or one of DSI’s other great modules) and use that plus a controller keyboard of your own choosing. But it’s nice to see this all-in-one design.

The Mopho sounds as nice as ever: listen to the original model for an idea.

Specs, as always: analog 2-oscillator, a nice switchable Curtis low-pass filter, fun step sequencer and arp, USB and MIDI. So you get lots of fun in one package, and a package you can easily lift.

Specifics, from DSI:

100% analog signal path
Two oscillators capable of producing sawtooth, triangle, saw/triangle, and variable pulse width square waves, with hard sync
Two sub-octave generators (one octave below oscillator 1 and two octaves below oscillator 2)
One classic Curtis low-pass filter (switchable 2- or 4-pole) with audio rate modulation, self-oscillating in 4-pole mode
Analog VCA
Three envelope generators (ADSR plus delay)
Feedback loop with programmable level and gain
White noise generator
4 LFOs
Gated 16 x 4 step sequencer (one sequence per program)
Glide (portamento): separate rates per oscillator
Full-sized, 44-note (F to C), semi-weighted keyboard action with velocity and aftertouch
Full-sized modulation wheel and spring-loaded pitch wheel
Fully programmable with 3 banks of 128 user programs (384 total)
