What's synthesizer?
It's a machine that uses artificial means to generate music. We synthesize chemicals by putting unnatural chemicals together. We synthesize sounds by putting unnatural sounds together.
Additive / subtractive
Additive: Adding multiple signals together. Some electric organs?
Subtractive: Subtract parts from a rich signal
History of Synthesizer, in one sentence
They kept getting smaller.
MIDI
Uses a clock signal that goes through all components to trigger stuff. Hmm. This might be helpful for recreating a synthesizer web app.
Waves
Filter
Cuts out certain frequency in the sound.
Modulation
Take a signal and use it to modify some other signal. e.g. LFO uses another wave form to control a low cut filter...? There are many different modulators.
Because everything in synthesizer can be described as a set of numbered attributes, these numbers can all be controlled.
