Until now, we produced only static spectra from a single sine wave. Let's change the
spectrum some more, and add liveliness to the sound:
5. Play a note and increase the Formant parameter.
You hear that a formant in the spectrum moves up. A formant is a group of
frequencies in the spectrum that is emphasized. The pitch of the sound does not
change, because the grain duration is not modified. If you take a look at the
waveform display, you see that the higher the Formant setting, the longer the
portion of the sample that is played back within the grain.
6. Play a note, and decrease the Length parameter.
The Length parameter has an effect similar to the Formant parameter. By
decreasing the length, the grain is shortened, but the period at which the grains
repeat stays the same. Therefore, only the spectrum of the sound changes, but not
its pitch.
7. Open the modulation matrix, select "Grain Formant" or "Grain Length" as
modulation destinations, and select a modulation source, for example "Filter
Envelope" or "LFO 1/2".
This adds more liveliness to the sound.
8. Adjust the modulation depth, and listen to the result.
9. Try out your settings with a more complex sample.
10.Click the waveform to change the position of the grain playback. The spectrum
changes accordingly.
11.Adjust the filter, envelope, and effect settings to your liking, and save your sound
as a preset.
The Formantor preset from the factory library is a good example for a pad sound
created using short grains.
Tutorial 3 – Low-Fidelity Time Stretching
1. Select the Cosmic sample from the "Padshop/05 Musical Fx" folder.
2. Set Speed to +100 % and Number to 2.
These settings assure that the sample plays back at its original speed, using two
grain streams that overlap completely.
3. Play C3 to listen to the sample as it was recorded.
4. Play a note, and decrease the Speed setting to +1 %.
The pitch of the sound is one octave above C3. This is because the two grain
streams that play the same sample are 180° out of phase, thereby cancelling out
the root of the sound.
5. Adjust the "Position Offset" parameter.
The two grain streams play at different sample positions and the root is not
canceled out any longer. The pitch returns to C3.
6. Select a different sample and see how it sounds with your settings.
7. Adjust the filter, envelope, and effect settings to your liking, and save the sound as
a preset.
The "Cosmic Bend Down" preset from the factory library is a good example for a
sound that was produced this way.
