Using Sampled Instruments
Use the lter, envelopes, and effects to shape the sound:
To modify the raw Prophet VS waveshape:
1. Set lter cutoff to 100 and lter resonance to 200.
2. Set lter env amount to 23 and set the lter envelope to attack 70,
decay 76, sustain 0, and release 72.
3. Set the amp envelope to attack 110, decay 85, sustain 0, and release 71.
4. To add some chorus, press the effect 1 button.
5. Turn the effect type knob and select chorus.
6. Set mix to 64, then set parameter 1 (depth) to 37, parameter 2 (rate) to
100, and parameter 3 (lpf) to 209.
7. Now, to add some lter modulation, in the lfo section, select lfo 2 and
set its shape to random.
8. With the LFO 2 parameters shown in the main display, press Soft
Button 3 to select the lfo dest menu tab, then select cutoff with Soft
Knob 1.
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.
9. Set LFO 2 frequency to 178 and the LFO amount to -69.
10. Play some chords. The sound is reminiscent of the Prophet VS —
minus the joystick.
Manipulating Samples and Loops
Another way to create something new from an existing instrument is to
edit the sample itself, by changing its sample start, end, loop attributes,
or reversing it. This applies the changes to all samples in the instrument.
Not all samples in the internal library are looped. But you can activate a
sustain loop in any sample/instrument by pressing the
loop button (if it’s
not already on) and adjusting loop attributes as necessary. In a sustain
loop, the loop repeats as long as you hold down a key.
Reversing a sample
One simple way to change the sound of a sample is to reverse it.
To reverse a sample:
1. Recall the Basic Program and turn Oscillator 1 level down to 0.
2. In the Sample Playback section, use the type knob to select percussion.
3. Use the instrument knob to select assorted bongos and play a few
notes.
4. Press the reverse button. Play and hold a few notes again to hear the
difference.
Because most of the samples have long “tails” (which are now the start
of the sample) you have to hold down the keys long enough to hear the
samples now that they are reversed. You can adjust the beginning and
end points of the samples if you want to accommodate for this. You’ll
learn how in the next example.
