25Prophet X User’s GuideOscillatorsTry using the auxiliary envelope to sweep the pitch of Oscillator 1 when it issynced to generate the classic, hard-edged sync sound.Slop 1&2: 0…127 – Adds randomized detuning to the oscillators toemulate the tuning instability of vintage analog oscillators. This tuninginstability is a big part of what made vintage instruments sound charac-teristically warm and fat. The oscillators in the Prophet X are very stable,and will not drift unless configured to do so. Use slop 1&2 parameter todial in as little or as much drift as you like.Additional Oscillator Parameters (Display Menu)Additional oscillator parameters are accessible through the menus in themain display. To see these menus, adjust any control in oscillators sectionof the front panel.TAB 1 - Osc TuneFREQUENCYFrequency Osc SlopFine Tune Key FollowFINE TUNE0 0C2 KEY FOLLOWOSC SLOPOsc1 MiscOsc1 Tune Osc1 SelectOsc1 ShapeFrequency: Sets the base frequency of Oscillator 1 or 2 over a 9-octaverange from 16 Hz to 8KHz (when used with the Transpose buttons). Adjust-ment is in semitones.Fine Tune: -50...+50—Fine tune control with a range of a quartertone upor down. The 12 o’clock position is centered. Steps are in cents (50 cents =1/2 semitone).Osc Slop: 0…127 – Adds randomized detuning to the oscillators toemulate the tuning instability of vintage analog oscillators.
