• PW – Pulse width (50-99%), waveform selector middle position only. • PWM – Pulse width LFO amount, waveform selector right position only. • PWM RATE – Speed of the PWM LFO. PROGUE - User Manual - Ver.1.0 - OVERVIEW - 3 -... - Page 4 • KEY TRACK – Controls the amount of keyboard control voltage applied to the filter. CONTOUR GENERATOR SECTION (ENVELOPES) Progue has two Contour Generators (Envelopes): the top one controlling the filter and the bottom one controlling the amplitude (VCA). • ATTACK – Attack time of generated envelope.

• Use GATE SYNC for phase syncing OSC1 and OSC2 to get invariable transients. • For max low frequencies turn EMPHASIS to minimum. • If EMPHASIS is used – overdriving with OSC1 and OSC2 to compensate low-end loss. PROGUE - User Manual - Ver.1.0 - SOUND CHARTS - 9 -... -
