36 X-Mod Dave Smith Instruments
Pulse Width: (Individually selectable for Oscillator 1 and Oscillator 2)
When Oscillator 1 or 2 are set to square wave, this modulates the pulse
width of the wave. Use a sine wave LFO to create a chorus-like effect
often used to emulate strings.
Amp: Selects the amplitude level as a modulation destination. Use a sine
wave LFO to create a tremolo effect.
Filtr Freq: Selects the lter cutoff frequency as a modulation destination.
Use a sine wave LFO to create an auto-wah effect when in low-pass lter
mode. Modulating the lter at high frequencies can create interesting
timbres.
Filtr Mode: Selects the lter mode as a modulation destination, changing
smoothly between low-pass, notch, and high-pass modes. Modulating the
lter at high frequencies can create interesting timbres.
X-Mod
Although the overall sonic character of the OB-6 is determined by its
analog oscillators and lters, much of its power to make truly unique and
unusual sounds comes from the X-Mod section.
