Program Play Mode
Envelope Delay Hold
Each of the three envelopes in a single Sound – Pitch (PENV), Filter (FENV) and
Amp (AENV) – can now have their "Delay" parameter set to wait for a note to be
released before continuing on to the other stages of the envelope. This is done by
setting the envelope's "Delay" parameter to 100. When this is done, the value for the
"Delay" parameter will read "HOLD", indicating that the "Hold" parameter has been
enabled.
Normally, the "Delay" parameter determines how long the envelope will wait once a
note has been played before it continues on to the other stages (Attack, Decay, etc.).
When this is set to "Hold", the envelope will wait until the note is released before
continuing on.
Note: The "Hold" feature requires that the "Trigger" function be set to Freerun.
Luckily, Freerun mode is forced to be on whenever "Delay" is set to "Hold",
regardless of the "Trigger" parameter's setting. When setting the "Delay" back to a
value between 0 and 99, Freerun mode is automatically disengaged, so you don't
have to change the "Trigger" mode manually.
"Hole in the Middle" Range Setting
It is now possible to create a "hole" in the middle of the keyboard for a Sound by
setting the Range function so that the Low Limit is higher than the High Limit. The
range of notes between these two pitches will be silent, while notes above the Low
Limit and below the High Limit will continue to trigger the Sound.
This may be additionally augmented when the Program is used in Mix Play Mode,
whereby the Mix's own Range settings can be manipulated to make the Sound
appear to have two isolated keyboard ranges. Example: If the Sound's Range is set
so that the Low Limit is C4 and the High Limit is C3 (thus creating a hole from C3 to
C4), you could then use the same Program in a Mix and set the Mix's Range so that
the Low Limit is C2 and the High Limit is C5. The Program will now play only between
C2 and C3, and C4 and C5; it will not sound below C2, nor between C3 and C4, nor
above C5.
New Pitch Mode
The Keyboard Mode of each Sound in a Program (Program Edit Mode, Pitch Function,
Page 3, Quad Knob [4]) now has a fourth mode, called "1-PMONO". In this mode, the
keyboard is monophonic (triggers only one note at a time) and has no pitch control.
Mod Wheel to Filter Modulation Routing
Formerly, the Pitch Bend Wheel was automatically routed to the Filter (Program Edit
Mode, Filter Function, Page 2, Quad Knob [1]), where you could adjust the amplitude
of its modulation between -99 and +99. This has been replaced with the Modulation
Wheel, for a more usable modulation function. Any Programs which formerly used
this direct modulation to have the Pitch Bend Wheel affect the Filter's cutoff
frequency will now have the Modulation Wheel performing this modulation in its
place. If you prefer to have the Pitch Bend Wheel affect the Filter, you can always
leave this parameter set to "00" and route the Pitch Bend to the Filter in the
Modulation Function.
Quantize Added to Modulation Routings 4 – 6
