Quad polyphony-oriented envelope with jammable universal controls

Quantus Trajecta is a quad envelope designed with polyphony in mind. Each control universally adjusts all four envelopes, so keeping separate voices related on the fly is easy. Initially designed to borrow the structure of the envelope from the Cursus and Loquelic Iteritas Percido, we added even more shape control with the addition of Tremolo and ADSR modes. QT is musical, performable, and utilitarian.
