An extensive music composition and analysis tool. An indispensable resource for any musician or music teacher interested in dodecaphonic and set theory analysis. • Enter a tone row by touching the staff or playing the piano keyboard. • It lets you know if any notes are repeated by highlighting both notes, checking enharmonic values regardless of octave or accidentals. • Automatically creates the Prime, Inversion, Retrograde, and Retrograde Inversion Magic Square. • Constantly updates the Interval Vectors and Circular Analysis of the tone row as you edit it. • Save your rows (rows may contain from 1 to 12 notes), complete with name and current P, R, I, RI matrix markings. Saved rows appear in a list with their name and midi numbers to help you identify them. • Share a pdf of the notation, piano keyboard, and circular analysis. • Watch and listen to your row played with a selected rhythm pattern. • Playback: - Prime - Prime then Retrograde - Retrograde then Prime - Retrograde - Inversion - Inversion then Retrograde Inversion - Retrograde Inversion then Inversion - Retrograde Inversion • Each can be repeated and transposed with each iteration. • The Root is kept within an octave above and below the original pitch when looping and transposing. • Matrix Audio: Hear the pitches as you mark them in the matrix square. The marks indicate the row form in which the pitch belonged; Prime, Inversion, Retrograde, and Retrograde Inversion. • Lock the prime row and transpose it to C to use the Absolute Pitch Method for row labeling in the matrix. Comes preloaded with the following rows: Alban Berg's Lyric Suite Babbitt's Composition for Four Instruments Schoenberg's Variations for Orchestra Op.31 Schoenberg's Piano Piece Op.33a Webern's Concerto Op.24 Webern's Piano Variations Op.27 Webern's String Quartet Op.28

Turn your iPhone, iPad or Mac into a customizable MIDI controller. Plug in your synth, pick parameters by name, and start playing in seconds. Condukt connects to any class-compliant USB MIDI device. No adapters. No manual CC programming. Just plug in and go. ▸ PLUG AND PLAY Connect your synth via USB-C. Condukt recognizes it instantly. Pick parameters from a list, filter cutoff, oscillator pitch, envelope attack, and you're controlling it. No more digging through manuals for CC numbers. ▸ RUNS IN YOUR AUv3 HOST (NEW) Load Condukt as an Audio Unit inside AUM, Loopy Pro, Logic Pro for iPad, Cubasis or Drambo. It follows host transport and tempo, so every sequencer starts on the host's downbeat. Run as many instances as you like, each with its own board, clock and patch cables, and your host project saves and restores all of it. ▸ SEVEN SEQUENCERS Conduktor, Phrase, Drum, Arpeggiator, Turing Machine, Cartesian and Painter. Draw chords with a finger or Pencil, program a XOX drum grid with polyrhythmic track pages, or let a Turing Machine find the pattern for you. One clock runs them all. ▸ POWERED BY midi.guide Condukt uses the midi.guide open-source database with MIDI definitions for hundreds of synths, drum machines, and effects. Community-maintained and constantly growing. ▸ BUILD YOUR OWN BOARDS Create custom control surfaces tailored to your workflow. Sequencers, faders, crossfaders, recall buttons: arrange them however you want. Save multiple boards for different setups. ▸ DO WHAT YOUR HARDWARE CAN'T - Add multiple LFOs to synths that only have one - Shape any parameter with the new Step Modulator - Control the same parameter across multiple tracks with a single fader - Instant snapshot recall for live performance - Sophisticated generative sequencers ▸ MULTI-DEVICE CONTROL One board can control multiple synths simultaneously. A single "Filter" fader can adjust cutoff on your Minifreak, Digitakt, and Moog at the same time. ▸ PERFORMANCE LAYOUTS Switch between layouts on the fly. Page 1 for sound design. Page 2 for performance. Page 3 for mixing. All within the same board. ▸ SNAPSHOT RECALL Store and recall control settings instantly. Tap and hold to save. Quick tap to restore. Perfect for live sets. Add crossfaders and morph between saved scenes. ▸ FULLY THEMEABLE Condukt looks as good as it works. Custom themes make your controller visually distinctive, whether you're performing on stage or filming content. ▸ WORKS WITH Elektron (Digitakt, Syntakt, Octatrack, Analog Four, Model:Cycles, Model:Samples), Arturia (Minifreak, Microfreak, MiniBrute), Moog (Subharmonicon, DFAM, Mother-32, Matriarch), Teenage Engineering, Novation, Korg, Roland, Sequential, and hundreds more. ▸ MADE FOR MUSICIANS Built by synthheads for synthheads.
