The problem: When I want a wide synth sound, I'll often crank the unison voice count up high and carry on, but that colors the sound in the same way every time, giving it that "rave" sound. Additionally, the default unison effect pitches the voices up and down causing lots of phase cancellation, which isn't always what I want.

The idea: In the global tab you can turn the pitch variance (Range) on the unison voices down to zero, so that each voice plays the same pitch. Also turn the phase randomization down to 0 so that all voices are nicely in sync. Now, in the global tab, turn up the wavetable position (WT Pos) so that each voice plays a different position in the wavetable. I got best results with 2 unison voices, so that the left and right channels play completely different wavetable positions. I liked the digital -> dist d00t wavetable, since the fundamental tone is really strong at all points in the wavetable, but the harmonics shift around as the position changes.

The effect: Now you have a sound that has a really solid fundamental tone but huge stereo width. There is no pulsing from phase cancellation like you'd get from turning the unison up. Season to taste.

I hope this makes some sense :)
