+Each filter can receive an additional filter envelope controlling the cutoff value dynamically. It uses an ADSR envelope similar to the one used for amplitude. There is an additional parameter to control the depth of the filter modulation: `lpenv`|`hpenv`|`bpenv`.

 # Synths

-For now, [samples](/learn/samples) are the main way to play with Strudel.
-In the future, more powerful synthesis capabilities will be added.
-If in the meantime you want to dive deeper into audio synthesis with Tidal, you will need to [install SuperCollider and SuperDirt](https://tidalcycles.org/docs/).
+In addition to the sampling engine, strudel comes with a synthesizer to create sounds on the fly.

-## Playing synths with `s`
+## Basic Waveforms

-We can change the sound, using the `s` function:
+The basic waveforms are `sine`, `sawtooth`, `square` and `triangle`, which can be selected via `sound` (or `s`):

-<MiniRepl client:idle tune={`note("c2 <eb2 <g2 g1>>").s('sawtooth')`} />
+<MiniRepl
+  client:idle
+  tune={`note("c2 <eb2 <g2 g1>>")
+.sound("<sawtooth square triangle sine>")
+.scope()`}
+/>

-Here, we are wrapping our notes inside `note` and set the sound using `s`, connected by a dot.
+If you don't set a `sound` but a `note` the default value for `sound` is `triangle`!

-Those functions are only 2 of many ways to alter the properties, or _params_ of a sound.
-The power of patterns allows us to sequence any _param_ independently:
+### Additive Synthesis

-<MiniRepl client:idle tune={`note("c2 <eb2 <g2 g1>>").s("<sawtooth square triangle>")`} />
+To tame the harsh sound of the basic waveforms, we can set the `n` control to limit the overtones of the waveform:

-Now we not only pattern the notes, but the sound as well!
-`sawtooth` `square` and `triangle` are the basic waveforms available in `s`.
+<MiniRepl
+  client:idle
+  tune={`note("c2 <eb2 <g2 g1>>")
+.sound("sawtooth")
+.n("<32 16 8 4>")
+.scope()`}
+/>
+
+When the `n` control is used on a basic waveform, it defines the number of harmonic partials the sound is getting.
+You can also set `n` directly in mini notation with `sound`:
+
+<MiniRepl
+  client:idle
+  tune={`note("c2 <eb2 <g2 g1>>")
+.sound("sawtooth:<32 16 8 4>")
+.scope()`}
+/>
+
+Note for tidal users: `n` in tidal is synonymous to `note` for synths only.
+In strudel, this is not the case, where `n` will always change timbre, be it though different samples or different waveforms.

+<JsDoc client:idle name="vib" h={0} />

+<JsDoc client:idle name="vibmod" h={0} />

 ## FM Synthesis

+FM Synthesis is a technique that changes the frequency of a basic waveform rapidly to alter the timbre.
+
+You can use fm with any of the above waveforms, although the below examples all use the default triangle wave.

+## Wavetable Synthesis
+
+Strudel can also use the sampler to load custom waveforms as a replacement of the default waveforms used by WebAudio for the base synth. A default set of more than 1000 wavetables is accessible by default (coming from the [AKWF](https://www.adventurekid.se/akrt/waveforms/adventure-kid-waveforms/) set). You can also import/use your own. A wavetable is a one-cycle waveform, which is then repeated to create a sound at the desired frequency. It is a classic but very effective synthesis technique.
+
+Any sample preceded by the `wt_` prefix will be loaded as a wavetable. This means that the `loop` argument will be set to `1` by defalt. You can scan over the wavetable by using `loopBegin` and `loopEnd` as well.

+
+## ZZFX
+
+The "Zuper Zmall Zound Zynth" [ZZFX](https://github.com/KilledByAPixel/ZzFX) is also integrated in strudel.
+Developed by [Frank Force](https://frankforce.com/), it is a synth and FX engine originally intended to be used for size coding games.
+
+It has 20 parameters in total, here is a snippet that uses all:
+
+<MiniRepl
+  client:idle
+  tune={`note("<c2 eb2 f2 g2>") // also supports freq
+  .s("<z_sawtooth z_tan z_noise z_sine z_square>")
+  .zrand(0) // randomization
+  // zzfx envelope
+  .attack(0.001)
+  .decay(0.1)
+  .sustain(.8)
+  .release(.1)
+  // special zzfx params
+  .curve(1) // waveshape 1-3
+  .slide(0) // +/- pitch slide
+  .deltaSlide(0) // +/- pitch slide (?)
+  .noise(0) // make it dirty
+  .zmod(0) // fm speed
+  .zcrush(0) // bit crush 0 - 1
+  .zdelay(0) // simple delay
+  .pitchJump(0) // +/- pitch change after pitchJumpTime
+  .pitchJumpTime(0) // >0 time after pitchJump is applied
+  .lfo(0) // >0 resets slide + pitchJump + sets tremolo speed
+  .tremolo(0) // 0-1 lfo volume modulation amount
+  //.duration(.2) // overwrite strudel event duration
+  //.gain(1) // change volume
+  .scope() // vizualise waveform (not zzfx related)
+`}
+/>
+
+Note that you can also combine zzfx with all the other audio fx (next chapter).
