Modulation
LFO 1 is set to modulate the pitch of all four oscillators, but as its initial source
amount is zero, the extent of its eect is controlled by the modulation wheel.
Velocity is set for positive modulation of the lter and amplier envelope
amounts. Hence, the harder a key is played, the louder the sound is produced
--along with increased amounts of the detuned thirteenth harmonic (which
adds to the program's metallic sound).
A small amount of keyboard modulation of the lter cuto frequency evens the
tone of the program across the keyboard.
Voice Control
Program Volume is set at 50, as is the velocity modulation source amount,
allowing key velocity to drive the volume to its maximum. Unison and Glide
are both o, and all voices are panned to the center. Should you want to
arpeggiate with this program, rearranging the voices in the stereo image would
produce lively, constant motion.
Chorus
The chorus is used in a somewhat unconventional manner. The rate is set
quite high, and the depth is very low. This causes a subtle trembling of the
oscillators that is not apparent at rst. If desired, adjust Chorus Amount for a
more exaggerated eect.
In short, this program demonstrates how dierent waveforms may be detuned,
and dynamically-mixed subtly for convincing eects, and how the chorus may
be used for other purposes than thickening the sound.
