hen you play a note, the envelope advances the position
through the wavetable, generating different waveforms
over time.
The decay stage would move through these waves in the
opposite direction prior to holding a certain wave during
its sustain stage. When you release the note, the envelope
continues the move back through the waves to the starting
point.
Most wavetables are created so that they start with a hol-
low wave at position 0 and go through increasingly brigh-
ter waves up to maximum position. This results in a beha-
viour similar to a low pass
�
ilter so that they can be conve-
niently controlled by an envelope.
If Attack is 0 and Decay set to a medium value you get a
percussive sound; if you turn up the attack, you get a soft-
sounding start.
You can also use an LFO to modulate the wavetable positi-
on and, depending on the selected
LFO Shape
, you might
get a wave scan that goes back and forth (triangle), in only
ione direction followed by a hard reset to the origin
(sawtooth) or between only two waves (square).
Exceeded Waves of a Wavetable
Of course you can combine envelope and keytrack modula-
tions or add other modulation sources. All these modulati-
ons will be added such that the end or the beginning of a
wavetable might be exceeded. In such cases, the waves will
be cyclically repeated.
