Prologue

This means that you should turn off the Osc 1 output when using frequency

modulation.

• The Freq Mod button activates/deactivates frequency modulation.

• The Ratio parameter determines the amount of frequency modulation.

Portamento

This parameter makes the pitch glide between the notes you play. The parameter setting

determines the time it takes for the pitch to glide from one note to the next. Turn the knob

clockwise for longer glide time.

The Mode switch allows you to apply glide only if you play a legato note. Legato mode only

works with monophonic parts.

Ring Modulation

Ring modulators multiply two audio signals. The ring-modulated output contains added

frequencies generated by the sum of, and the difference between, the frequencies of the

two signals. In Prologue, Osc 1 is multiplied with Osc 2 to produce sum and difference

frequencies. Ring modulation is often used to create bell-like sounds.

• To hear the ring modulation, turn down the output level for Osc 1 and 2, and turn up

the R.Mod level all the way.

• If Osc 1 and 2 are tuned to the same frequency and no modulation is applied to the Osc

2 pitch, nothing happens.

However, if you change the pitch of Osc 2, drastic changes in timbre can be heard.

If the oscillators are tuned to a harmonic interval, such as fifth or octave, the ring

modulated output sounds harmonic, other intervals produce inharmonious, complex

timbres.

• Deactivate oscillator sync when using ring modulation.

Noise Generator

A noise generator can be used for simulating drum sounds and breath sounds for wind

instruments, for example.

• To hear only the sound of the noise generator, turn down the output level for the

oscillators, and turn up the Noise parameter.

• The noise generator level is routed to Envelope 1 by default.
