#What you'll learn

What every slider group in the right panel does, and which ones matter for which sound.
How to build a sound from up to 4 layers that start at different times.
How to use seeds, History and Favourites so you never lose a good sound.
How to use the layer effects and seamless loops for spells, beams and ambience.
How to send sounds to Pixxune, Pixxara and Pixxizi through your Pixx library.

#Before you start

You should be comfortable with the basics in the Pixxibu Beginner guide: presets, Mutate and Export.
Headphones help: small changes to filters and pitch are easier to hear.
Saving to the cloud and the library needs a signed-in account with Pixxibu in your plan.

The right panel shows the selected layer. Each group shapes one part of the sound:

Wave: pick the tone (Square, Saw, Sine, Noise, Triangle, Breaker). Square duty and Duty sweep change how hollow a square wave sounds and let it shift over time. Volume lives here too.
Envelope: Attack, Sustain, Punch and Decay set the length. Each slider shows its value in milliseconds.
Pitch: Start pitch (shown in Hz), Min pitch (a floor the slide stops at; off at 0), Slide and Delta slide (a slide that speeds up or slows down).
Vibrato & arpeggio: Vibrato depth and Vibrato speed wobble the pitch; Arp change and Arp speed jump to another note partway through, the classic power-up step.
Filters: Low-pass cutoff, Low-pass sweep and Resonance dull the sound or make it "wah"; High-pass cutoff and High-pass sweep thin it out.
Effects: Repeat speed restarts the sound quickly (alarms, rapid fire), Phaser offset and Phaser sweep add a swirl, Tremolo depth and Tremolo speed pulse the volume.

Make the first part, for example an Explosion for the crack.
Click + Layer under the waveform (or As a new layer under Presets) to add a second sound made from the current preset type. You can have up to 4 layers.
Click the new layer's tab and shape it, for example a low Noise rumble with a long Decay.
In the Layer section at the top of the right panel, set Starts at (0 to 2 seconds) to delay it, and Layer gain (0 to 2) to balance it. Small marks on the waveform show where each layer starts.
Use M and S on the layer tabs to mute or solo a layer while you work.
Duplicate copies the selected layer, Reset turns it back into a plain square tone, and Remove deletes it.

Every new sound goes into History (the last 20). Click an entry to restore it.
The Seed box in the options bar shows the number behind the last preset. The same seed always makes the same sound, so write it down or type it back in later.
The 🎲 next to the seed keeps the same preset and rolls a new seed.
In Spell kits, click ☆ on any role to add it to Favourites, then switch the filter from All elements to your favourites to see only those.
Your current sound, history and export options are kept on this device automatically, so a reload doesn't lose them.

Open Layer effects in the right panel. Each layer has its own effects:

Pitch shift (semitones): move the whole layer up or down by up to 24 semitones. It works like speeding up or slowing down a tape: +12 is an octave higher and half as long.
Ring-mod depth and Ring-mod pitch: metallic, robotic or bell-like tones.
Drive (saturation): grit and loudness. Bitcrush and Sample-rate crush: lo-fi crunch.
Stutter and Stutter length: random short chunks repeat the chunk before them, a glitchy skip. Stutter length sets the chunk size.
Reverse: plays the layer backwards, great for "sucking in" charge-ups.
Echo mix, Echo time and Echo feedback: a fading echo for caves, big spells and UI confirmations.

Open Layer effects and tick Seamless loop (whole sound).
Pixxibu crossfades the end of the whole sound into its start, so it repeats without a click. The looped sound is slightly shorter than before.
Play it with Space a few times to check the join, then export it as usual.

Click Send to App and choose This sound (WAV).
Pick Pixxune (music), Pixxara (dialogue blips and cues) or Pixxizi (game packages), or save it to your library.
The sound travels with its full Pixxibu recipe. If you later open it in Pixxibu from Library, every layer and slider comes back editable.

In Spell kits, pick one element, for example Storm.
Click each role you need (Cast / charge, Projectile / whoosh, Impact) to load the reference versions.
Adjust each one with the same habits (for example a little Echo mix on all of them) so the set feels consistent.
Star each finished role, then export each one or send them to your library.

Make one good sound.
Click Export and open Batch variations.
Set How many (2 to 50) and Change (1% to 30%), then click Download ZIP. The first file is your original; the rest are small variations.
In your game, pick one of the files at random each time.

Make a short Blip / select for a character's voice blip.
Send to App → Pixxara, and use it as the speaker's blip there.
For the whole scene, export the dialogue from Pixxara to Pixxizi, which packages the sounds with it.

Space play and stop · M mutate · Ctrl+O open · Ctrl+S export · Esc close windows.
Mutate more under Presets makes bigger changes than Mutate.
Turn off Auto-play in the options bar if you want to adjust many sliders without hearing each change.
The readout at the right of the options bar shows the length and number of layers.
Opened WAV files play and export but can't be edited with the sliders. Pick a preset or move a slider to go back to the synth.

The new layer button is greyed out: you already have 4 layers. Remove one first.
The sound got much louder after adding layers: layers add up. Lower Layer gain on each layer, or Drive.
A loop still clicks: make sure Seamless loop (whole sound) is ticked, then lower any long Echo tail, which can make the join audible.
A library sound opens as a plain WAV: it was made outside Pixxibu (or before its recipe was saved), so only playback and export work.
The sliders don't respond: you're playing an imported WAV. Pick a preset or click a slider group to start a new synth sound.
