Add effects to your Logic Pro Sculpture bass sound
Detuning and ensemble effects are normally achieved using a modulation effect or by
combining doubling and detuning. When you are using a fretless bass for a solo part, a
broad chorus effect adds a nice touch.
Because Sculpture can synthesize only one note at a time at any given pitch, simple
doubling isn’t an option. There are, however, alternatives for bringing movement and life
into the sound. Almost all of the type parameters of the different objects can be modulated
by LFOs, resulting in a vast number of possible combinations.
As a rule, basses are mixed without effects (dry), but a small amount of reverb can be quite
appealing on a fretless bass, when used as a solo instrument. Use the Delay section to
emulate this. Heavy delays are, however, used on basses in “dub” style reggae.
Emulate a chorus effect by modulating pickup positions in Sculpture
1. In Logic Pro, make sure the Fretless Roundwound#1 setting is loaded.
2. Adjust the position of PickupB to 0.20.
3. Drag the Spread Pickup semicircle—which is beside the Level knob—upward.
Both of the light blue dots move downward toward the letters L and R.
You can hear how the stereo breadth of the fretless sound has increased. PickupA is
sent out on the right channel, while PickupB occupies the left channel.
Note: Although only modern basses offer such stereophonic features, it’s still fun to
process conventional sounds with this effect. Note that not all pickup positions are
monophonic-compatible. You can check this by returning the Spread Pickup setting to
monophonic—click the Spread Pickup semicircle while pressing the Option key.
Animate the pickup positions in Sculpture
1. In Logic Pro, select LFO1.
2. Click the 1button (next to the RateMod slider, at the upper right) to activate the first
modulation target.
3. Choose PickupPos A-B as the modulation target.
4. Set the Rate knob to 1.00Hz.
5. To hear the effect, you need to set the modulation intensity (amount). Familiarize
yourself with this effect by moving the amt slider gradually to the right. Set it to a final
value of 0.15, a moderate rate that doesn’t wobble too much.
6. Save this setting as Fretless Chorus Dry.
