4 phase-aligned formant oscillators
Four phase-aligned formant oscillators. Follows the outline in Puckette's book, adding frequency shift and mix controls for even/odd partials and Cauchy/Gaussian shape. Two versions available, with (for R 6.4) and without (for R 6.2.2) front panel patching.
v1.1: Added controls for frequency sync. See info hints.
v1.2: Changed the way of computing bandwidth. Now it refers to the area concentrating half the output power, as in bandpass filters. Relative bandwidth is now considered symmetrical in frequency (instead of pitch) around the center.
