- SYNTHS
- VCO
- voltage controlled oscillator
- varies oscillation based on voltage input
- electronic oscillator
- VCA
- voltage controlled amplifier
- gain varies based on control voltage
- controls output
- LFO
- low frequency oscillator
- also amplitude modulation
- usually below 20hz
- creates rhythmic pulse or sweep
- VCF
- voltage controlled filter
- filter cutoff points based on control voltage
- MIDI= musical instrument digital interface
- a language, NOT an analogue synths
- one of the reasons people now prefer software plug ins
- additive synthesis
- timbre is created by adding sine waves together
- subtractive synthesis
- parts of an audio signal altered or remove by a filter
- automation
- when musical instruments are programmed to do things automatically
- e.g a sequenced trumpet could be automated to pan left- right
- cant do it on analogue synths
- portamento- allows you to slide from one note into the next
- modulation- allows you to 'sculp' the sound
- ADSR
- attack
- how soon the note comes in after hitting the key
- decay
- how quickly the note starts to wear off after you take your finger off the key
- sustain
- how long the note lasts
- release
- how soon the note stops after you take your finger off the key
- attack
- VCO
