LinPlug Spectral - Manual (Page 75)

Precision
The Precision control can be used to set the accuracy of the Spectral's
signal generation. When it is set to less than 100% small inaccuracies are
introduced at many different points in the Spectral's signal chain. This is
useful if you're aiming to replicate the warmth of an old analog synthesizer.
Voice Limit
The Voices control is used to set the number of voices (polyphony)
available. Settings available include Mono and various amount of notes
from 1 to 16.
One thing that may be confusing is the difference between Mono and 1
setting. It can be explained as follows: Say that you hold down one key and
then press and release a second key. In the case of the Mono voice setting,
the first note will sound, and then the second note sounds. When the
second note is released the first note sounds again. This creates a pedal
tone effect typical for monophonic synthesizers. When set to 1 after
releasing the second note, the first will not sound again. In this case only
the amount of voices are limited to 1, just like with any other limit value.
Also, when playing overlapping notes, with “1” Envelopes and LFO's will re-
trigger with each note, while with “Mono” they wont.
Learn
The Learn makes it simple to control Spectral from an external MIDI
controller (either hardware or software).
To access the MIDI Learn click on the MIDI Learn button which is located
on the lower right of the Spectral’s front panel. This opens a popup menu
containing the following items: Off, Learn, Clear, Clear All, Load, Save and
Edit.
To use the Spectral’s MIDI Learn feature, select “Learn” from the popup
menu. Select a Spectral parameter with the mouse by clicking on it and
then move your MIDI Controller (This sends some MIDI messages to
Spectral). You can do this for multiple Spectral parameters in a row, always
click (the parameter) and move (the controller). When done, click on “Off”.
