The other modulation mode is ÒOscÓ. In ÒOscÓ mode, the algorithm inputs and outputs are stereo, and the
carrier signal for both channels is generated inside the algorithm. The carrier signal is the sum of Þve
oscillators (see Figure 10-60).

Four of the oscillators are simple sine waves and a Þfth may be conÞgured to one of a variety of wave
shapes. With all oscillators, you can set level and frequency. The conÞgurable oscillator also lets you set the
wave shape. Available shapes are Sine, Saw+, Saw-, Pulse, Tri and Expon (Figure 4). Sine is simply another
sine waveform. Tri produces a triangular waveform, and Expon produces a waveform with narrow, sharp
peaks which seems to rise exponentially from 0. Pulse produces a series of square pulses where the pulse
width can be adjusted with the ÒOsc1PlsWidÓ parameter. When pulse width is 50%, the signal is a square
wave. The ÒOsc1PlsWidÓ parameter is only active when the Pulse waveform is selected. Saw+ and Saw-
produce rising and falling sawtooth waveforms. The Pulse and Saw waveforms have abrupt,
discontinuous changes in amplitude which can be smoothed. The pulse wave is implemented as a hard
clipped sine wave, and, at 50% width, it turns into a sine wave when set to 100% smoothing. The sudden
