Before you start making your first sounds, it's worth understanding the interface layout. It was designed with simplicity, ergonomics, and eye protection in mind (thanks to a modern, dark theme) for late-night production sessions.

Main Toolbar

Anchored at the very top of the screen, the Central Toolbar is precisely divided into 6 functional groups. Below is a documented description of each visible control:

Transport Controls

• Play / Stop: The main button that starts and stops playback. It changes shape (a triangle when idle, a square during playback). In "Stop" mode, it simultaneously resets clips scheduled for playback in Session View and restores effect modulations to their initial state.
• Record (Circle icon): When recording is active, the icon vibrates with a warning color. When used with the built-in drum synthesizer TOMiC, an additional MIDI switch appears on the adjacent bar. This lets you decide whether to send sound to the arrangement view as raw audio (Bounce) or record the hits as a programmable MIDI clip.

Position Display

• A central, darker block displaying the current playback time in the musical format BAR:BEAT:TICK. A Tick operates at a high resolution of 960 PPQ, ensuring super-precise internal engine positioning.

Global Controls

• BPM (Tempo): Allows you to enter the song's speed within the range of 40.0–240.0. Changing the tempo on the fly intelligently maintains correct timeline scaling.
• VOL (Volume): The main knob setting the overall volume level of the entire application (range from 0 to 100%).
• SWING: A digital slider that imparts a rhythmic offset to the meter (from 0% to 100%), providing a "swinging" and "humanized" character to repeating beats.
• Groove Template: A dropdown button for "Groove" presets. Besides the "Straight" (None) option, you can apply algorithmic offsets modeled after legendary samplers MPC: 54%, 60%, 67% and 71%.
• Time Signature: A slider (from 1 to 16) and a separate dropdown list representing the musical denominator (1, 2, 4, 8, 16). E.g., indicated as 4/4 or 3/4.

Project & Export

• New: A clean slate (Shortcut: Ctrl+N). Absolutely clears and resets the entire engine from scratch.
• Save: The save procedure (Shortcut: Ctrl+S). Omni generates its own project file with an .omni suffix in JSON text format, which binds the parameters of each track and connected plugin instruments into one secure document.
• Load: Loads a previously existing project.
• Export: Opens the offline rendering panel ("Bounce to WAV"), unlocking the configuration window (16/24 bit depth, with an enabled algorithm adding TPDF dither and limiting).

Edit & History

• Undo / Redo: Buttons allowing safe step-backs in the history system (Shortcuts: Ctrl+Z and Ctrl+Y). If there is no action in history, they will remain dimmed.

View & External IO

• Sess/Arrange (Toggle Views): Instantly switches OMNI's workflow paradigm from the DJ-like Session View to the linear mode known as Arrangement View (This toggle is often mapped to the "Tab" key).
• ⌨ MIDI (QWERTY Keyboard): Activates support for entering notes using the typing keyboard. The tool will notify you of the starting octave. The 'Z' row is the lower octave, the 'Q' row is the upper one. You control higher layers with 'Ctrl + UP/DOWN Arrows'.
• MIDI IN: Shows the actively attached and listening MIDI keyboard. Port refresh option available.
• Settings: Navigates to system settings (including audio interface buffer size configuration).
