Cursus Iteritas
Dynamically generated wavetable oscillator using orthogonal functions.

Interface

All knobs on Cursus Iteritas function as offsets for the input jacks. The controls
function similar to a bandpass filter; center, width, and tilt allow the filter to be
asymmetric.
Pitch
1v/8va pitch control. For more control, see Range below.
Center
selects the center harmonic used to build the wavetable.
Structure
allows selection of harmonics included in the output. In the center
position, all harmonics are included. Fully left only even harmonics; fully right,
only odd.
Edge
controls the oversampling filter of the wavetable. As this is turned to the
right, it will add musical overtones.
Fold
wavefolder. Enough said.
Width
controls how many different harmonics are used to create the wavetable.
Tilt
weights the spread of harmonics. In the middle it is symmetric; at left,
lower harmonics are louder while at right, higher harmonics get more volume.
Sync
triggers oscillator reset. Responds to a rising edge of about 3v.
Mode
selects which orthogonal function set is used to produce the wavetable
Range
two-octave offset pitch ranges
Out
audio output - 10vpp
Voltages
CI's CV ins respond to 0-5v, except the pitch in, which responds to 0-8v.
