Synthesizers
Create sound in oscillator based on waveform which is filtered and modulated.
Circuit - synth
Keystep - keyboard
Oscillator:
Create sound in oscillator: Smooth shape, smooth tone , hard; hard tone
| Sin | Simple | Muted Warm Hollow Bassy | Flute Organ |
| Triangle | Simple few overtones (not as full as square) | Pure, Dull | Chime, Organ |
| Saw wave | Complex excitements and bright at hi end in upper range. | Full Harsh Bright | string |
| Square | Complex harmonics, full sound Can be shape no other can | Hollow Harsh Brass ruddy | Horn |
| Square Pulse | Square with variation in timing | ||
| Noise | very Complex many overtones. Hard Cutting | Asymmetric | Noise |
- 1.00 Hz A frequency of one hertz means that a full oscillation (or cycle) happens once per second
- Pulse width - How long on top and how long down: The wave has its “fullest” sound at the center, where the waveform is symmetrical.
Low Frequencies oscillator LFO:
Low frequency oscillator generate waveform (e.g. sin) like oscillator and using it as control signal modulator
Examples :
- source » destination e.g. LFO can modulate filter frequencies
- can create pitch vibrato
- pulse width modulation with Square wave
Filter
Shape sound and character of waveform
- open, close
- resonance
| Lowpass | Cut off Highend frequencies | (traditional ?) duller | ||
| Highpass | Cut off Lowend frequencies | (more esoteric ? ) | ||
| Bandpass | Low + High | |||
| Resonance | Peak before high cut. Add sharpness. | Laser zaps, Focused sounds | ||
| Sweep | Move resonance center | |||
| Key track | Low same but higher notes have higher filter (more open) frequencies / high-end on high notes | |||
| Envelope | ie: Open and Close filter over time | |||
| Cutoff frequency | Take out of focus | |||
| Drive | ||||
| Env2 Mode | how much filter env modulate filter frequencies |
- if you low pass filter saw wave you will get sth like sin
Envelope ADSR
How fast turn on and down. Determine how much envelop impacts settings. U can modulate: filters, pitch, frequencies, pulse with modulation(shape square wave), amplifier.
envelope’s shape with each new note, some aspect of sound
| - | how long it takes for the envelope to | - | immediate | long |
|---|---|---|---|---|
| Attack | reach its peak at the start of a note | Hit and Hold | drums | wind |
| Decay | decrease from its peak to the sustain level | Hold | sharp change | |
| Sustain | Rest state | Hold Rest state | ||
| Release | decrease to its minimum level after the note is released | Immediately after release |
Modulation
Modulate Wave with additional waves. Using signal to shape aspect of sound over time
