Dave Smith Instruments

Tetra takes the award-winning sound and features of Mopho, multiplies them by four, and packs them in a box less than half an inch larger!Tetra has multiple personalities. It is a four-voice, analog poly synth, a sort of “mini Prophet.” It's a four-part, multitimbral synth with separate outputs, essentially four Mophos in one very compact box. And it’s a voice expander for other Tetras or the Prophet ’08.Affordable, fully programmable poly synth with a 100% analog signal path.Classic, real analog sound—including legendary Curtis analog low-pass filter.Four-part multitimbral capability with four separate outputs.Combo Mode for huge unison patches, stacked sequences, and "modular-style" poly sounds.Expandable: poly chain with other Tetras, Prophet '08, and Mopho for expanded polyphonyJust 7.9" x 5" (20.07 cm x 12.7 cm).Free editor for Mac OS and Windows.

The voice architecture of the Dave Smith Instruments Mopho is identical to a single voice of the Prophet '08, but with a couple of unique twists to distinguish it from its award-winning sibling.Dave Smith Instruments have added two sub-octave generators - one per oscillator - for additional girth and crushing basses. It also has an audio input that lets you process external audio and mix Mopho's own audio output back in pre-filter for feedback effects that can range from subtle distortion to extreme skronk.The Push It button is a manual trigger that lets you play a specific note or latch notes and sequences on. It can also step through a sequence to play short melodic lines without a keyboard. Of course, Mopho can also be used with a MIDI controller or external sequencer.Mopho is fully programmable and all the parameters can be tweaked from the front panel. The four Assignable Parameters controls are assignable per program for optimum performance control. A free editor is available for Mac OS and Windows to facilitate programming. (And, if you already have a Prophet '08, most of Mopho's parameters can be controlled from the Prophet's front panel via MIDI!)Mopho is perfect for people who want to learn the ins and outs of real analog synthesis without spending a bundle, DJs looking to add some old school sonic spice to their setups, and musicians who will appreciate a great-sounding, very portable mono synth. Dave Smith Instruments Mopho main features include: Affordable, fully programmable mono synth with a 100% analog signal path.

The Dave Smith Instruments Prophet 08 Module is an eight-voice tabletop "knobby" module with all of the features and controls of the Prophet '08 Keyboard (minus the keyboard, of course) in an even more compact enclosure, with a 100% analog signal path.With real analog oscillators, famed Curtis low-pass filters, and analog VCAs, the Prophet '08 Module is capable of reproducing the familiar sounds of its legendary predecessors. But modern features like a greatly expanded modulation matrix and additional modulation sources—like three envelopes and four LFOs per voice—take it way beyond the vintage gear and make this a worthy and unique addition to the Prophet family tree.Dave Smith Instruments Prophet 08 Synthesizer Module features include a gated 16 x 4 step sequencer, arpeggiator, split or stacked key modes with separate stereo outputs per layer, and rack ears for optional rack-mounting. The Prophet '08 module can also be used as an expander to increase the polyphony of another Prophet '08—keyboard or module—to 16 voices.Dave Smith Instruments Prophet 08 Module main features include: The only affordable, full-featured polysynth with a 100% analog signal path Classic, real analog sound—including legendary Curtis analog low-pass filters—married to a modern feature set Small footprint, huge sound 4U Rack mountable Tons of knobs for direct, real-time editing and performance Used as an expander, increases polyphony of another Prophet '08 to 16 voices Two digitally controlled analog oscillators per voice Classic Curtis analog low-pass filters Extensive modulation routing capabilities Four-on-four splits and layers with separate stereo outputs for each layer Arpeggiator, gated 16 x 4 step sequencer, and LFOs all syncable 2 digitally controlled analog oscillators (DCOs) per voice with selectable sawtooth, triangle, saw/triangle mix, and pulse waves (with pulse-width modulation), and hard sync White noise generator 1 Analog Curtis low-pass filter per voice, selectable 2- and 4-pole operation (self-resonating in 4-pole mode) 3 Envelope Generators: filter, VCA, and assignable (four-stage ADSR + delay); Envelope 3 can loop 4 LFOs Glide (portamento): separate rates per oscillator Analog VCAs MIDI In, Out, Thru, and Poly Chain Main stereo audio output: 1/4" unbalanced Output B stereo audio output: 1/4" unbalanced Sustain pedal input: accepts normally on or normally off momentary footswitch Pedal/CV input: responds to expression pedals or control voltages ranging from 0 to 5 VDC (protected against higher or negative voltages) Headphone output: 1/4" stereo phone jack Includes power supply for 110V – 240V AC operation (13-15 VDC, 400 mA) and operation manual.
