wave, higher values widen it. At the extreme values, the pulse goes completely 
flat, which allows for some interesting possibilities with pulse width modulation. 
Glide: 0...127—Sets the oscillator glide (portamento) rate. Glide can be set 
independently for each oscillator. Low values are faster. See also “Glide Mode” 
in Other Oscillator Parameters. 
Sub Octave: 0...127—Controls the level of a square wave pitched one octave 
below oscillator 1 or two octaves below oscillator 2. 
Other Oscillator Parameters 
These additional, less performance-oriented oscillator controls are found in the 
Miscellaneous Parameters section. 
Oscillator Sync: Off, On—Turns oscillator hard sync on. With sync on, 
whenever oscillator 2 resets, oscillator 1 is forced to restart. 
Tip: Try routing an envelope or the mod wheel to oscillator 1 frequency 
for the familiar sync sweep sound. 
Oscillator 1 Keyboard Tracking: Off, On—Turns keyboard tracking off or on 
for oscillator 1. 
Oscillator 2 Keyboard Tracking: Off, On—Turns keyboard tracking off or on 
for oscillator 2. 
Oscillator Slop: 0...5—The amount of random oscillator frequency tuning slop. 
The analog oscillators in Mopho x4 are very accurate, and will not drift. This 
works great for accurate sounds, and allows precise de-tuning. Oscillator Slop 
allows subtle amounts of frequency drift. For larger amounts, use a random LFO 
or white noise mod.
