  • Page 15: Frequency

    FREQUENCY Lowpass The frequency determines the operating point of the filter in the spectrum. The lowpass filter removes high frequencies from the signal. All frequencies above the cut off frequency are reduced gradually. For example a low pass filter will cut off all frequencies above its set cutoff frequency (all frequencies below it pass the filter unaltered –...

  • Page 21: Introduction To Drum Synthesis

    INTRODUCTION TO DRUM SYNTHESIS 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. This chapter will introduce you to the very basics of drum synthesis.
  • Page 22 Amplitude envelope Oscillator We want a sharp percussion sound, so the attack will stay at zero. A single white noise oscillator set to its maximum frequency. 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 Filter give you a short hit sound with a nicely decaying noise tail.
