the Mod Matrix (Glide Time).
Rate When set to Rate, the amount of time it takes to move from one note
to the next depends upon how far apart the two notes are. The further apart
the notes, the longer it will take for the pitch of the first note to reach that of
the following note. This parameter can be modulated using the Mod Matrix
(Glide Time).
Note that the Time/Rate dial itself can either adjust an un-synced time
(thats a constant time, no matter what tempo your DAW is reporting to
Spectral) or (when you click the note icon) a synced time in a wide range
so the timing of Glide is always in sync with the song or project tempo.
Glide Routing
Next are a number of switches allowing you to define in detail how the
Glide is actually working in this specific preset.
First is a line allowing you to define whether or not Glide is affecting the
Oscillator pitch. While this usually is what is most typical in Glide it can be
turned of on an per-Oscillator basis for special effects.
The next line allows this for the Filter frequency, providing the the Pitch
Track parameter of the Filter is set to any non-zero value. Again, while for
the usual Glide effect you will want this to happen, you can turn it off here.
The final line allows to define which of the 4 Modulation Sources will be
glided. Usually when playing successive notes, these Modulation Sources
will change instantly from one note to another, however, with Glide they
gradually change (or not, when switched Off here).
NOT (Note) This is not to be confused with the first line (Oscillator
Pitch), this is about the Note being used as a Modulation
Source in the Matrix.
VEL (Velocity) This affects three points in the signal flow: The effect of
Velocity to the Main Volume, the effect on Filters (when
Velocity Tracking) is set and the use of Velocity in the
Matrix.
ALT (Alternate) The Alternate modulation source in the Matrix
RND (Random) The Random Unipolar and Random Bipolar modulation
sources in the Matrix
