What is a synthesizer ?

Components of a sound :

  • Pitch
  • Tone
  • Volume

OSC

Filter

LFO

Amplifier

Arturia MicroBrute

OSCILLATOR

AMPLIFIER

ADSR Envelope :

  • Sets the maximum volume of the sound

+

FILTER

  • Alter the frequency spectrum of a sound choping frequences, not dealing with bass, mids or highs
  • 3 main types of filters :
    • ​Low Pass Filter
    • High Pass Filter
    • Band Pass Filter

Low Frequency Oscillator

  • Infrasonic : usually below 20 Hz
  • Used to modulate the sound over time
  • It is defined by :
    • a waveforme
    • a frequency (rate)
    • an amplitude
    • and a destination

Attack longer

  • Play long notes 

Raise sustain

  • Note stopping to fast

Add release

  • Copy envelope to filter
  • CutOff at 0
  • Raise the envelope depth
  • Too static

LFO

The Trumpet(2/2)

  • Vibrato
  • Vibrato is instant 

Pitch depth

Fade Time

  • Tremolo

Amp Depth

  • Wha Effect

Filter Depth

You got your trumpet !

More ?

  • No attack / No sustain / a bit more decay

Kind of Banjo 

  • Even more decay

Kind of guitar
