## What is J.J.Breeze AUv3 Plugin?

jj-breeze is a stereo micro-pitch widener with vibrato and a warmth tone stage. It is an Audio Unit (AUv3) effect for iPhone and iPad.

PRICING
Free download. Full effect for 7 days from first launch (no signup). Then unlock permanently for a one-time purchase ($2.99 in the U.S. — price varies by region). No subscription.

Open the app, tap Play, and listen to a built-in demo through the effect. Turn knobs, throw section switches, pick a panel finish (Field Green or Slate), and try factory presets. After you have launched the app once, the same plug-in is available in GarageBand, Logic for iPad, AUM, and other AUv3 hosts as: jj-breeze.

WHAT IT DOES
Shift creates width or a full-band pitch change with independent left and right pitch (±1 octave) and delay, plus a Focus crossover so the low end can stay dry. Vibrato adds a slow delay-based pitch wobble. Warmth is a final tone stage: low-shelf body, low-pass, and gentle saturation.

SECTIONS
• Shift — Pitch L/R, Delay L/R, Focus, Mix
• Vibrato — Rate, Depth, Mix
• Warmth — Tone, Drive, Body, Mix

Each section has its own bat switch. Turning a section off removes it from the sound without wiping the knobs.

PANEL
Retro hardware look with two finishes — Field Green and Slate — chosen with a rotary selector. IN/OUT LED meters in the header. Save As… for user presets; swipe to rename or delete.

FACTORY PRESETS
Default, Stereo Width, JJ Cajun Moon, JJ Lies, JJ Dark Vocal, Octave Width, Deep Baritone, Slapback Twang.

IN A DAW
1. Install and open jj-breeze once (this registers the Audio Unit).
2. GarageBand: Audio FX → Audio Unit Extensions → jj-breeze
3. Logic for iPad: Audio Units → Gerov
4. AUM and other AUv3 hosts: look for: jj-breeze

This app is a working host, not an empty wrapper. You can hear and edit the effect without leaving the app. Microphone input in the host is optional (Demo Loop is the default).

jj-breeze is an original effect. It is not affiliated with any third-party plug-in vendor or recording artist.
