Appendix D: What’s New in the 2.0 “Plus” Upgrade

142 S4 Plus Reference Manual

Among the 6 possible modulation routings, routings 4 through 6 have had their Gate

parameter replaced with a new Quantizing parameter (Program Edit Mode, Mod

Function, Pages 4–6, Quad Knob [4]). These modulations are now referred to as

Quantize Modulation Routings. The “Quantize” parameter can be turned on or off.

When “Quantize” is turned on, the modulation effect will be stepped. When off, the

effect will be smooth, or linear.

Example:

If you were to route the Modulation Wheel to

Pitch with an amplitude of +99, moving the Mod Wheel while the Quantize parameter

was off would cause the pitch of a held note to slide up, much the same way it does

when the Pitch Bend Wheel is used. However, moving the Mod Wheel while the

Quantize parameter was on would cause the pitch of a held note to rise in half-step

increments.

LFO Waveforms

The 3 LFOs, (PLFO, FLFO and ALFO) each have a new waveform. The existing

waveform called “Random” (which is bipolar), is now called “RANDOM +-”. The new

wave form is called “RANDOM+”, and is positive only. Additionally, the Saw waves,

which were formerly bipolar (both positive and negative), are now positive only.

Pitch Envelope Gated Release

The Pitch Envelope Function (PENV) can now have its release stage bypassed. This

is important when you want the Pitch Envelope to remain at its Sustain Level setting

after a note has been released. If the PENV’s “Release” parameter is set above 100,

the display will read “HOLD” indicating that the Pitch Envelope will remain at it the

level indicated by its “Sustain” parameter even after a note is released.

In addition, if the AENV’s “Trigger Mode” parameter is NOT set to either “Reset” or

“Reset-Freerun”, playing legato will cause new notes to begin at the selected Voice’s

loop point instead of its start point. This is important with Voice’s that include attack

transients, such as the breathy attack of a flute sound. By beginning the sound of

these notes at their Voice’s loop point, the attack transients will not be retriggered.

Non-Retrigger Legato

If a Sound’s “Keyboard Mode” parameter is set to “Mono” (Program Edit Mode, Pitch

Function, Page 3, Quad Knob [4]), each of the three envelopes (PENV, FENV and

AENV) will not retrigger when playing legato, except when the “Trigger Mode”

parameter of each envelope is set to either “Reset” or “Reset-Freerun”.

Tracking Generator

The Tracking Generator Function now generates two types of modulation sources:

Normal and Stepped. When selecting the Tracking Generator as a modulation source

in the Mod Function, these two choices will be available.

When “TRACKGEN” is selected as the modulation source, the Tracking Generator

functions normally, scaling its input as determined by its parameter settings. When

“STEPTRACK” is selected as a modulation source, the Tracking Generator’s output

will be stepped, or interpolated. This means that instead of scaling the input linearly

from point to point, the input is kept at each point’s value setting until it goes beyond

the following point’s value setting, at which point it jumps to that setting. This feature

is very useful in creating “mini-sequences” if the modulation destination is set to

“Pitch” and the Tracking Generator’s input is an LFO using an “Up Sawtooth” as its

waveform.
