Pitcher
Pitcher applies a lter to the input signal which has a series of peaks in the frequency
response.
ese peaks are normally adjusted so that their frequencies are all multiples of a specic,
selectable frequency, which imposes a strong sense of pitch at the selected fundamental
frequency.
Pitch. e fundamental pitch imposed upon the input, in MIDI note numbers from C-1 to
G9. Ptch Ost is an oset from the pitch frequency in semitones, from -12.0 to 12.0. It can
be useful to assign pitch bend, a ribbon, or another continuous controller to this parameter
through a MOD.
Odd Wts, Pair Wts, Quartr Wts, Half Wts are parameters that control the shape of the
frequency response of Pitcher. An exact description of what each one does is, unfortunately,
impossible, since there is a great deal of interaction between them. For more information
and examples, see the KSP8 Algorithm Reference Guide available as a free download at www.

Ring Modulation
Ring modulation multiplies two signals (the “carrier” and the “modulator”) together to
produce unusual, often non-harmonic, overtones. e Ring Modulator eect in the Forte
SE has two modes: “L*R” in which two mono signals are modulated together; and “Osc”,
in which the input is stereo, and it is modulated with the sum of ve waveforms that are
generated from oscillators within the eect itself. Four of these oscillators are sine waves,
while one (Oscillator 1) oers a selection of waveforms.
Wet/Dry. When the eect is in “L*R” mode, this controls how much of the left signal only is
passed dry (the right signal isn’t passed dry at all).
Mod Mode selects between the two modes, L*R or Osc.
Osc1 Lvl is the level of Oscillator 1, from 0 to 100%.
Osc1 Freq is the frequency of Oscillator 1, from 16 to 25088 Hz.
Osc1 Shape is the waveshape of Oscillator 1, selectable from Sine, Saw+, Saw-, Pulse, and
Tri.
Osc1PlsWid (Pulse Width). When Osc1 Shape is set to Pulse, this sets the pulse width as
a percentage of the waveform period. When the width is set to 50%, the result is a square
wave. is parameter has no eect if other waveform types are chosen. Range is 0 to 100%.
Osc1Smooth smooths (removes the higher harmonics from) the Saw+, Saw-, and Pulse
waveforms. A Sawtooth wave becomes more like a triangle wave, and a Pulse wave becomes
more like a sine wave. Range is 0 to 100%.
e other four oscillators, Sine2 through Sine5, each have Lvl and Freq controls.
