title: Jon Audio Zebra Operation Notes
h1:

These are my notes from the [Jon Audio Youtube channel](https://www.youtube.com/@jonaudio).
These are the notes on operation of Zebra, such as what modules do what.
For sound design, [see here](Zebra_JonAudio_SoundDesignNotes).


```glish
Osc Fx
======

We have two effect slots.
You have to play with them
to hear how they sound.

1. Fundamental: amps or attens the fund
2. Odd For Even: to right = odd harmonics, to left = even
3. Brilliance: affects upper harms
4. Filter: sharp slope filter as it acts on spectrum
           before rendering to wave
5. Bandworks: right = bandpass, left = notch
6. Registeriser: emph octaves, atten all else
7. Scrambler: see docs
8. Turbulence: see docs
9. Expander: amp strong harms, atten weak
10. Symmetry: like pwm for general waves
11. Phase Xfer: use wave to mod sine
12. Phase Root: FM thing again
13. Trajector: FM thing again
14. Ripples: see docs
15. Formantzilla: formants, see docs
16. Sync Mojo: sync
17. Fractals: like sync but fills space in self-sim way
18. Exophase: 7 stage phasor applied to orig wave
19. Scale: rel amps of harms scaled
20. Scatter: see docs, noisy
21. ChopLift: negative attens weak harms, pos raises amps harms
22. Hypercomb: a bit like unison, adds 3 copies to wavetable
23. Phase Dist: see docs
24. Wrap: folds down signal above thresh
25. DX: Like Trajector but stronger
26. Smear: Blur spectru

Resonator
=========

FX grid: Res 1.

Res is a filter bank like.
Four bands, each freq, emph, gain.

Color selects analog filter models.

Mode lp, bp, bpi inverts second filt, hp

Bands can be modulated.
```

Ring Modulation
===============

Osc 1 to second lane and mute.
FMO 1 in lane 1. FM by input.
Ring in lane 1. Input from lanes 1 and 2.
Osc 1 sine tree.
