Portamento
Portamento
[Off, On]
Portamento lets the pitch glide smoothly between notes, instead of changing abruptly.
On: Turns on Portamento, so that pitch glides smoothly between notes.
Off: Turns off Portamento. This is the default.
Fingered
[Off, On]
Fingered applies only when Portamento is On.
On: Playing legato will turn on portamento, and playing detached will turn it off again.
Off: Legato/detached playing will not affect portamento.
Type
[Constant Rate, Constant Time]
Constant Rate: Portamento will always take the same amount of time to glide a given distance in pitch—for instance,
one second per octave. Put another way, gliding several octaves will take much longer than gliding a half-step.
Constant Time: Portamento will always take the same amount of time to glide from one note to another, regardless of
the difference in pitch. This is especially useful when playing chords, since it ensures that each note in the chord will
end its glide at the same time.
Time
[0.0000...50.0000 secs or secs/octave]
This controls the portamento time. If Type is set to Constant Rate, the units are secs/octave (seconds per octave). If
Type is set to Constant Time, the units are simply secs (seconds).

Notes on Amp Modulation
Amp modulation scales the Amp Level and Amp Envelope, with an upper limit of 2x the original settings to prevent
uncontrollably loud output. If the original level is low, the maximum modulated volume will also be low.
(For the technically inclined: Amp modulation is multiplicative. Modulation values are offset by +1.0, so that a value
of 0 has no effect. The maximum modulation value—for example, moving the Mod Wheel all the way up—doubles the
volume level if the Intensity is +100%, or brings the level to silence if the Intensity is -100%.)
Tip: To start with a low level (or silence) and then use modulation to raise the level to maximum, use the Filter Output
Level instead.
Level
[0%...100%]
This sets the basic volume of the Program, optimized for per-voice modulation. For adjusting the volumes of Programs
within a Performance, it's better to use the Layer Volume instead.
Amp LFO Intensity
[–100%...+100%]
This controls the amount of modulation from the Amp LFO.
Velocity
[–100%...+100%]
This reduces volume according to velocity.
With positive (+) values, the volume decreases as you play softer.
With negative (–) values, the volume decreases as you play harder.
