32 Effects Dave Smith Instruments
FL2:
This is a vintage flanger without a feedback path and is designed to
emulate the through zero capability of tape deck flanging. Use it to add
a sweeping flanged effect to a sound. Adjustable parameters are rate and
depth.
PH1:
This is a vintage phaser emulation with high resonance. Use it to
add a deep, sweeping, swirling resonant effect to a sound. Adjustable
parameters are rate and depth.
PH2:
This is a vintage phaser emulation with lower resonance. Use it to
add a swirling resonant effect to a sound. Adjustable parameters are rate
and depth.
PH3:
This is a faithful emulation of Tom Oberheim’s original phaser
design. Use it to add a swirling resonant effect to a sound. Adjustable
parameters are rate and depth.
rin:
This is a faithful emulation of Tom Oberheim’s original ring modula-
tor design. Use it to add a complex harmonic effect to a sound. Adjust-
able parameters are the modulation frequency and low note pitch track-
ing on/off.
The ring modulator’s mode of operation is determined by the setting of Param-
eter 2, (pitch tracking) which can be set to either on or off. With this parameter off, the
ring modulator functions like the original Oberheim unit. In this mode, pitch tracking is
off, and Parameter 1 sets the modulation frequency, which remains the same regard-
less of what note you play on the keyboard. With parameter 2 on, the ring modulator
tracks the pitch of the lowest note that you play on the keyboard. In this case the
Parameter 1 sets a ratio between the lowest note that you play and the modulator note
(instead of setting a fixed frequency). The modulation frequency will then change as
you change the lowest note that you’re playing, so that the ratio will remain constant
between the note that you play and note of the modulator. If you are only playing one
note at a time, then the ring modulator will modulate with the same ratio as you play
up and down the keyboard.
Set Parameter 2 to the “on” position to get more musical results from the ring
modulator.
