Modulation is the process of varying a parameter dynamically over time; the oscillator pitch can be modulated by envelope, keyboa[...]

Editing Programs: Chapter 6 Each voice/filter combination is followed by an amplifier whose level can be controlled by a variety of modulation sources. This allows for creating sounds with percussive or slow attacks, particular types of decays, tremolo, etc. Filter and amp settings can interact. If the filter cutoff is extremely low, then no signal[...]

Chapter 6: Editing Programs LFO (L OW F REQUENCY O SCILLATOR ) The pitch, filter, and amp modules each have a dedicated LFO module for modulation. The term LFO stands for low frequency oscillator, and comes from how modulation was created in the early synth days (an oscillator set to a low frequency could modulate some aspect of the sound; routing [...]

Chapter 6: Editing Programs Sound Overlap (00 to 99) Page 6 This determines how many voices can overlap on the same pitch. Example: If you hold the sustain pedal down and play the same note over and over, Sound Overlap determines how many voices are available for that note, and thus how many voices will overlap (play simultaneously). In the old day[...]

Editing Programs: Chapter 6 PITCH ENVELOPE The Pitch Envelope function (press [90]) can lead to dramatic effects, since it can cause the pitch of a single key to change drastically over time. It’s typically used in special-effect synthesizer programs, but it may also be used more subtly in an acoustic program to simulate the characteristic of som[...]

Chapter 6: Editing Programs Delay (00 to 99, Hold) Page 5 This is the amount of time that the envelope will wait before doing anything; very useful if you want to affect one element of a sound sometime after the sound starts. When the Delay is set to 0, the envelope attacks right away, without any delay. Play some notes while turning up the delay a[...]

Editing Programs: Chapter 6 Sustain Pedal (On or Off) Page 9 This determines whether or not the Sustain Pedal will have an effect on the envelope.

Chapter 6: Editing Programs Time Tracking (On or Off) Page 8 This determines whether or not keyboard position will affect the cycle speed of the envelope. When turned on, playing toward the higher end of the keyboard will result in a faster envelope cycle; playing toward the lower end of the keyboard will result in a slower envelope cycle. However,[...]

Editing Programs: Chapter 6 M OD 1 – M OD 6 About General Purpose Modulation Although there are several dedicated modulators in the QS (e.g., the pitch can always be modulated by the pitch LFO and Pitch Envelope), sophisticated synthesizer programming demands the ability to use as many modulation sources as possible to modulate as many modulation[...]

Chapter 7: Editing Effects Stereo Chorus. In the case of a Stereo Chorus, the signal is split into three parts with a dry signal and a separate Detuning section for both left and right channels. When the left channel is detuned sharp, the right is detuned flat, and vice versa. Once again, this causes the effect to become more pronounced and dramati[...]

Editing Effects: Chapter 7 Stereo Flange. In the case of the Stereo Flange, the signal is split into three parts with a dry signal and a separate Delay section for both left and right channels with one channel flanging up while the other channel flanges down. Once again, this causes the effect to become more pronounced and dramatic. Pitch Detune. A[...]

Editing Effects: Chapter 7 Pre-Delay Mix (<99 to <0> to 99>) Page 8 This allows you to mix the amount of Pre-Delay into the Reverb signal path. This gives you the ability to hear a bit of the Reverb before the loudest part of the Reverb (the Pre-Delayed Reverb) sounds. This makes for bigger and smoother sounding Reverb settings. Input F[...]
