Creating Stereo Synth Brass
Here’s another easy-to-construct sound: synth brass, with a classic “pitch
blip” effect on the attack. In this example you’ll learn how to pan the
oscillators hard left and right to create an ultra-wide stereo spread, how
to detune the super saw wave, and how to use an auxiliary envelope to
modulate the pitch of oscillator 2 to simulate an aggressively blown horn
effect.
To create synth brass:
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 super saw and set
shape mod for osc 1 to 45 and osc 2 to -45 to detune and thicken them.
5. With the Mixer parameters shown in the display, press Soft Button 2
to select panning, then set osc1 pan to -64L and osc2 pan to 63R for an
ultra-wide stereo spread.
6. In the oscillators section, set slop 1&2 to 15 to add a little analog-
style oscillator drift.
7. In the filter section, set cutoff to 10, resonance to 5, and drive to 100.
8. In the filter envelope section, set the env amount to 80, the attack to
16, decay to 88, sustain to 58, and release to 90.
9. Enable touch sensitivity by pressing and enabling the velocity button.
10. In the auxiliary envelope section, select envelope 3 and set its
destination to osc2 freq. This routes envelope 3 to modify osc 2 pitch
according to its ADSR (attack, decay, sustain, release) settings. This
will create the slight pitch variation at the beginning of the sound (the
“pitch blip”).
You can quickly assign the mod destination for Envelope 3 by holding down
the envelope’s selector button and turning the Oscillator 2 frequency knob. This will
auto-assign the modulation destination to the envelope.
11. Set the auxiliary env amount to 40 and decay to 30.
12. Play some single notes and chords in the upper range of the keyboard.
Classic synth brass!
13. Experiment with different auxiliary env amount and decay settings to
ne tune the “pitch blip” effect.
Turning the Synth Brass Sound into a String Pad
It’s a simple matter to turn the previous synth brass sound into a string
pad by simply adjusting its envelope and lter settings.
To turn the synth brass into a string pad:
1. In the filter section, set the cutoff to 87.
2. In the filter envelope section, set the env amount to 7.
3. Set lter envelope attack to 52, decay to 102, sustain to 81, and
release to 100
4. Set amplier envelope attack to 73, decay to 62, sustain to 127, and
release to 80.
5. Play some chords. You’ve now got a good basic string pad.
Adding Effects to the String Pad
You can enhance the string pad adding an effect such as phasing for a
retro feel.
To add effects to the string pad:
1. In the effects section, press the effect 1 button.
2. Turn the effect type knob and select phaser.
3. Set mix to 64, then set parameter 1 (depth) to 92, parameter 2 (rate) to
9, and parameter 3 (feedback) to 255.
4. Play some chords. Classic string machine! For even more dramatic
phasing, set mix to 127.
