The Quinta Pitch Machine is more than your standard octave in that it not only gives you notes an octave up and an octave down, but also gives you a fifth up. Each of the three intervals is dialled in proportion with its own knob, and you get a mix knob to blend dry and pitch-shifted sound, this runs from totally dry to totally pitch-shifted. Your Quinta Pitch Machine comes with 4 knobs. Three of these are used to add in the extra notes. The +1 OCTAVE knob adds a note that is 1 octave higher than the note you play on your instrument. The -1 OCTAVE adds a note that is 1 octave lower than the note you play. The +1 FIFTH adds a note that is a fifth higher than the note you play on your instrument. The last control on your Quinta Pitch Machine is the MIX control. This adjusts the balance between the natural signal coming from your instrument as you play it and the whole configuration of added octaves and fifths you have set up via the other knobs on your Quinta Pitch Machine. SONIC POSSIBILITIES - Octave up, octave down, 5th up - Individual volume controls, plus master mix - Replicate organ, synth or 12-string sound - Play power chords on a single note Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect
