8.1. Kicks
The basis of nearly every kick sound is the simple combination of an oscillator and a decaying
envelope modulating its pitch. The first 3 voices are perfect for this!
Oscillator
A good starting point is a sine oscillator with a pitch around 30 to 35.
Amplitude Envelope
To decide how to set up the envelope, let's think about the kick sound. A kick has a sudden impact,
so we want no attack (set to zero) since the sound starts with its maximum amplitude.
The decay controls the length of the kick sound. For the average kick a decay in the range 20-30
and a slope around 25 (exponential) gives a nice, not too short, not too long kick. For those
booming 808 kicks you may want to set the decay higher.
Pitch Envelope
To get some 'oooomph' and punch into your sound you need to set up the pitch envelope.
Try a decay and slope setting similar to the amplitude envelope as a start. All three parameters,
decay, slope and modulation amount, have a great impact on the sound of the kick.
Click
The attack sound is an important part of a kick. There is no general rule here. Try different transient
generator settings for various clicks and pops or even slightly increasing the amplitude attack to
give some softer bass drums.
Tips and tricks
• You can further shape the attack of the sound using the FM oscillator.
• You want even more clicks in the attack? Why not enhance the click with a peak filter?
8.2. Snare
The snare is a 2 component sound. There is the tonal part from the drum body and the noise part
from the rattles.
Voice 4 of the LXR is designed with these 2 parts in mind. You have an oscillator for the tonal part
and a noise generator with filter for the noise part. Since in most of the cases you want a highpass
filtered noise with an unfiltered drum body, only the noise generator is routed trough the filter.
For most snare sounds you want the noise part to be louder than the tonal part, so try setting the mix
parameter on the oscillator page to a value around 100.
