Creating a Hard-Sync Lead
Using the LFO to Sweep the Filter
You can further enhance the string pad by using the LFO to sweep the
lter.
To sweep the lter:
1. In the lfo section, select lfo 2 and make sure its shape is set to the
triangle wave.
2. With the LFO parameters shown in the main display, press Soft Button
3 to select the lfo dest menu tab, then use Soft Knob 1 to select cutoff.
You can quickly assign the mod destination for LFO 2 by holding down the
LFO 2 selector button and turning the Filter Cutoff knob. This will auto-assign lter
cutoff as the modulation destination for LFO 2.
3. With the LFO parameters shown in the main display, press Soft Button
1 to select the lfo shape menu.
4. Set the LFO shape to triangle, frequency to 30, and amount to 50.
5. Play some chords. The LFO sweeps the lter.
6. For fun, experiment with changing LFO 2’s shape, frequency, and
amount parameters.
Creating a Hard-Sync Lead
Here’s another classic sound: a hard-sync lead. A famous example of this
is “Let’s Go” by the Cars (performed on a Prophet-5). In this example
you’ll learn how to hard-sync the oscillators, pitch-modulate one of them
with an auxiliary envelope, then add effects.
To create a hard-sync lead:
1. Press the global button.
2. Use Soft Knob 1 to navigate to basic program and press Soft Button 1
(write now). As a shortcut, hold down the front-panel transpose down
button and press the hold button.
3. In the mixer, turn up Oscillator 2 to 127. (Osc 1 is already at 127.)
4. In the oscillators section, set both oscillators to sawtooth.
5. Enable the sync 2>1 button. (See “Sync 2>1” on page 24 for an
explanation of phase sync.)
6. Set the pitch of Oscillator 1 to C3. This will intensify the sync effect.
7. In the auxiliary envelope section, select envelope 3 and set its desti-
nation to osc1 freq. This routes envelope 3 to modulate osc 1 pitch
according to its ADSR (attack, decay, sustain, release) settings.
8. Set the auxiliary env amount to 127 and attack to 23, decay to 60,
sustain to 100, and release to 65. This will set the amount and “shape”
of the modulation.
9. Play some single notes and in the middle range of the keyboard. Clas-
sic hard-sync lead!
10. To make it a little edgier, set lter drive to 100, lter cutoff to 0, lter
envelope decay to 100, and lter env amount to 127.
Adding Effects to the Lead
You can enhance the sync lead by adding some delay and reverb.
To add effects:
1. In the effects section, press the effect 1 button.
2. Turn the effect type knob and select delay stereo.
3. Set mix to 22, then set parameter 1 (time) to 135, parameter 2 (feed-
back) to 47, and parameter 3 (lpf) to 100.
4. In the effects section, press the effect 2 button.
5. Turn the effect type knob and select super plate.
6. Set mix to 47, then set parameter 1 (time) to 100, parameter 2 (tone) to
138, and parameter 3 (predelay) to 12.
7. Play some notes. Searing hard-sync lead!
