MIDI communication is by standard MIDI in and out jacks or USB.  Poly Chain Out is a special, dedicated MIDI output to chain multiple instruments for increased polyphony.\u003c\/p\u003e\n\u003cp class=\"bodyindent\"\u003e\u003cstrong\u003eUnder the Hood\u003c\/strong\u003e\u003cbr\u003e The voice architecture is based on the Prophet '08, but with the addition of a sub-octave generator for each oscillator and a fully programmable feedback loop for each voice.  That breaks down to two DCOs, a resonant low-pass filter, three DADSR envelope generators, four LFOS, deep modulation routing, an arpeggiator, and a 16 x four analog-style step sequencer \u003cem\u003eper voice\u003c\/em\u003e.  Feedback is capable of producing effects ranging from mild distortion to fairly extreme harmonic instability.  The possibilities are nearly endless.  And the audio signal path is 100% analog.\u003c\/p\u003e\n\u003cp class=\"bodyindent\"\u003e\u003cstrong\u003eTetra a la Mode\u003c\/strong\u003e\u003cbr\u003e In Program Mode, Tetra is a four-voice, polyphonic synthesizer with four banks of 128 programs.  As with the Prophet '08, each program contains two layers—each layer is essentially a separate patch—that can be used to create keyboard splits or stacked sounds.  Banks one and two are the Prophet '08 factory programs; banks 3 and four are a combination of Mopho and new programs.\u003c\/p\u003e\n\u003cp class=\"bodyindent\"\u003eIn Combo Mode, a different program can be assigned to each of the four voices.  Combos can be used for mammoth unison patches or for triggering up to four different 16 x 4 sequences—each with its own program—simultaneously.  Combos can also be used to create \"modular-style\" polyphonic patches, where each voice plays a different program, with a slight variation on the same sound or even a drastically different sound.\u003c\/p\u003e\n\u003cp class=\"bodyindent\"\u003eIn Multi Mode, Tetra becomes a multitimbral sound module capable of playing four monophonic parts on four MIDI channels, with separate outputs for each voice. Coupled with a MIDI sequencer and DAW, Tetra can play complex arrangements or analog drum parts with each part individually processed and recorded to its own track.\u003c\/p\u003e\n\u003cp class=\"bodyindent\"\u003e\u003cstrong\u003eThis One Goes to 12...and 16\u003c\/strong\u003e\u003cbr\u003e Up to four Tetras can be poly chained for eight, twelve, or sixteen voices total. When used with a Prophet '08, up to two Tetras can be poly chained for a maximum of sixteen voices.  In addition, the Prophet's front panel controls map directly to almost all of Tetra's parameters, so the Prophet acts as a programmer and control surface.  And a Mopho can be connected to Tetra's Poly Chain Out for five-voice operation.\u003c\/p\u003e\n\u003cp class=\"bodyindent\"\u003e\u003cspan style=\"font-weight: bold;\"\u003eFeatures:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul class=\"indentlist\"\u003e\n\u003cli\u003eAffordable, fully programmable poly synth with a 100% analog signal path\u003c\/li\u003e\n\u003cli\u003eClassic, real analog sound—including legendary Curtis analog low-pass filter\u003c\/li\u003e\n\u003cli\u003eFour-part multitimbral capability with four separate outputs\u003c\/li\u003e\n\u003cli\u003eCombo Mode for huge unison patches, stacked sequences, and \"modular-style\" poly sounds\u003c\/li\u003e\n\u003cli\u003eExpandable: poly chain with other Tetras, Prophet '08, and Mopho for expanded polyphony\u003c\/li\u003e\n\u003cli\u003eJust 7.9\" x 5\" (20.07 cm x 12.7 cm)\u003c\/li\u003e\n\u003cli\u003eFree editor for Mac OS and Windows\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dave Smith Instruments","offers":[{"title":"Default Title","offer_id":44449330987111,"sku":"13766","price":575.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/davesmith_tetra_3.jpg?v=1787088583","url":"https:\/\/vintageking.mom\/products\/dave-smith-instruments-tetra","provider":"Vintage King","version":"1.0","type":"link"}
