Tonal part
The tonal part is quite similar to the kick but not as pronounced. The typical snare does not need a
loud click, nor that much modulation depth for the pitch envelope. Additionally, since a snare is
smaller than a bass drum, the frequency of the oscillator has to be higher than on the kick.
Noise part
For most cases highpass filtered noise with a moderate resonance setting is sufficient to get good
results.
Amplitude envelope
We want a sharp percussion sound, so the attack will stay at zero.
For the decay it depends on what kind of snare you are after.
•
Longer decay times with a very exponential slope setting as low as 5 to 10 will give you a
short hit sound with a nicely decaying noise tail. The tail acts a little bit like a room reverb
on the perception of the snare sound and gives more natural results.
•
Shorter decay times with a linear or exponential slope will give a very dry, direct snare.
Tips and tricks
•
Not every snare needs tone and noise. Try using only the tonal part with a high pitch
modulation envelope to get the classy Kraftwerk zap.
8.3. Clap
A clap sound is made from noise. What's special about a clap, is the fuzzy attack of the sound.
Imagine a few people clapping a rhythm. They will never all clap at exactly the same time. Each of
them will have small variations in their timing, some will clap a little bit earlier, some a bit later.
Amplitude Envelope
To simulate this behaviour we will use the repeat feature of the amplitude envelope. To get the
classic clap sound, a setting of 3-4 repeats is good. Since the timing differences for the clap are very
small, a short repeat time has to be chosen. An attack value below 10 is good.
Now you will have a short burst in the beginning of the sound.
For the decay we need an exponential slope. A value below 10 is recommended.
Oscillator
A single white noise oscillator set to its maximum frequency.
