# Superdirt synths
A list of available synths compiled from the source code comments and docs. Some synths like `superfm` were missing from the [Tidal documentation](https://tidalcycles.org/index.php/All_effects_and_synths) on synths, so I put together this list for a better personal reference.
Default values are in parentheses. Some undocumented parameters are included without descriptions. I might have forgotten some attributions and other tidbits in the process of editing the documentation, so please fill in what you see it's missing.
In all synths,`sustain` (default 1) affects the overall envelope timescale. The parameters `pan` and `freq` can also be set in all synths. The default value for `freq` is usually 440 -- in synths where it's not, `freq` and its default value for that synth are mentioned in its parameter list below.
## Instruments
### supermandolin
Physical modeling of a vibrating string, using a delay line (CombL) excited by an intial pulse (Impulse). To make it a bit richer, I've combined two slightly detuned delay lines.
- `sustain` (1) changes the envelope timescale
- `accelerate` (0) for a pitch glide
- `detune` (0.2)
### supergong
An example of additive synthesis, building up a gong-like noise from a sum of sine-wave harmonics. Notice how the envelope timescale and amplitude can be scaled as a function of the harmonic frequency.
- `voice` (0) provides something like a tone knob
- `decay` (1) adjusts how the harmonics decay
- `accelerate` (0) for pitch glide
For a demo, try `d1 $ n (slow 2 $ fmap (*7) $ run 8) # s "supergong" # decay "[1 0.2]/4" # voice "[0.5 0]/8"`
### superpiano
Hooking into a nice synth piano already in SuperCollider
- `velocity` affects how hard the keys are pressed
- `sustain` controls envelope and decay time

### superhammond
Hammond B3 sim
* `perc`, `percf` and `decay` are an attempt at the percussion, no idea if it sounds at all reasonable. Vintage Hammonds had percf as 2 or 3 (switchable), two perc levels (maybe roughly 0.7 and 1.2?), and two decay options (roughly 0 and maybe 1ish?)
* `vibrato`, `vrate`, `perc`, `percf` are all new parameters you'll need to define in Tidal if you want to change them
Voices are drawbar presets:
- 0: bass violin 16'
- 1: tibia 8'
- 2: bassoon 8'
- 3: french trumpet 8'
- 4: string ensemble
- 5: Blues

- `accelerate` (0)

- `detune` (0)
### superfm
6-op FM synth (DX7-like). Works a bit different from the original DX7. Instead of algorithms, you set the amount of modulation every operator receives from other operators and itself (feedback), virtually providing an endless number of possible combinations (algorithms).
- `voice` is the preset number: `0` is user-defined; `1-5` are randomly generated presets
- `lfofreq` is the overall pitch modulation frequency
- `lfodepth` is the overall pitch modulation amplitude
Each operator responds to
- `amp` (operator volume - becomes carrier)
- `ratio` (frequency ratio)
- `detune` (in Hz)
- `eglevel` (1-4) (4 envelope generator levels)
- `egrate` (1-4) (4 envelope generator rates)
The syntax for operator arguments is `<argumentName + opIndex>[modulatorIndex | egIndex]`. For example:
- `amp1 1` (op1 as carrier with full volume)
- `ratio2 2.3` (op2 frequency ratio)
- `mod11 0.5` (op1 feedback)
- `mod12 0.78` (op1 modulation amount by op2)
- `detune1 0.2` (op1 detune)
- `eglevel12 0.1` (op1 EG level2)
- `egrate11 0.01` (op1 EG rate1) -- WARNING: higher values go FASTER!
