Build: 232eca1 | November 8 – November 11, 2026
Hot on the heels of the modular sampler rebuild and the official debut of Omni Drum Synth, the Omni development team has delivered one of the most powerful sound design updates in the workstation's history. Over the past 72 hours, fourteen targeted commits have introduced a complete Instrument Rack engine (builtin://instrument-rack), fundamentally expanding what a single track can accomplish in Omni.
With Build 232eca1, producers can stack, split, crossfade, and temporally sequence up to 32 parallel instrument chains on a single track. Each chain hosts its own dedicated MIDI FX, native synthesizer or third-party plugin (VST3, CLAP, VST2, LV2), and independent insert FX chain. Coupled with a 16-knob macro matrix and a revolutionary TIME Zone sequencer that hands off a single held note between multiple synthesizers over time, Omni unlocks a new paradigm of generative sound design.
Here is the complete deep dive into the new architecture!
🎛️ The Instrument Rack Architecture: Up to 32 Parallel Chains
Previously, playing multiple synthesizers or layering plugins required routing across multiple auxiliary tracks. The new Instrument Rack lives natively in the instrument slot of any track, allowing unprecedented parallel routing within a unified, self-contained instrument device:
1. Fully Autonomous Signal Chains
Every Instrument Rack supports up to 32 independent parallel chains:
- Universal Instrument Hosting: Load any built-in instrument (Omni Synth, Omni Drum Synth, Sampler, Alchemy, Iris 2, physical modeling synths) or third-party VST3 / CLAP / VST2 / LV2 plugin on any chain.
- Per-Chain MIDI FX (Up to 8 Slots): Insert arpeggiators, scale quantizers, chord triggers, and note humanizers directly into a specific chain before its instrument. A single MIDI clip can trigger a straight chord on Chain 1 while generating a running arpeggio on Chain 2.
- Per-Chain Audio FX (Up to 16 Slots): Every chain includes its own dedicated post-instrument insert chain supporting both native processors and third-party plugin hosting with background loading off the audio thread.
- Integrated Channel Mixer: Each chain features tactile controls for Gain, Pan (with center-origin LCD indicators), Mute, Solo, Transpose, stereo L/R peak meters, and glowing LED note activity bars.
2. Multi-Zone Performance Filtering
Determine exactly when and how each chain responds to incoming notes:
- KEY Zones: Split your keyboard into distinct performance zones with adjustable crossfade zones to seamlessly blend between instruments across registers.
- VELOCITY Zones: Trigger different instruments, sample layers, or acoustic models depending on striking force, complete with velocity curve scaling.
- CHAIN Selector Zones: Smoothly crossfade between chains using a dedicated chain selector parameter — ideal for sweeping through distinct synth patches via macro knobs, automation, or modulators.
- One-Click SPREAD: Instantly distribute active keyboard ranges, velocity layers, or selector zones evenly across all loaded chains with a single click or context menu command.
- LAYER / CYCLE / RANDOM Modes: Play all matched chains simultaneously (LAYER), cycle through chains round-robin with each consecutive note (CYCLE), or randomly pick a chain on each trigger (RANDOM).
⏳ Groundbreaking TIME Zones: Temporal Note Sequencing
Perhaps the most innovative addition to the Instrument Rack is the TIME Zone engine (timer.rs), which reimagines notes as evolving journeys through multiple sound generators:
1. Morphing a Single Held Note Over Time
Rather than all instruments sounding simultaneously or choosing one instrument per trigger, TIME zones allow you to paint temporal spans along a timeline:
- Sequential Instrument Hand-off: Paint a time block for Synth A from 0 to 2 seconds, Synth B from 2 to 4 seconds, and Synth A again from 4 to 6 seconds. Pressing and holding a single key plays Synth A, seamlessly transitions into Synth B, and returns to Synth A without releasing the key!
- Sample-Accurate Note Runners: Powered by an allocation-free runner engine on the audio thread, note-offs release the currently sounding span cleanly without triggering future unreached blocks.
2. LOOP Mode & Generative Rhythms
- Continuous LOOP Mode: Toggle
LOOPto repeat a time pattern of lengthLENindefinitely for as long as the key is sustained, transforming held chords into pulsating rhythmic tapestries. - Interactive Timeline Painting: Click and drag on empty space to paint time blocks; overlapping spans merge automatically. Drag handles allow quick resizing, with snap grids down to 1/64 beat (or hold Shift for unquantized freeform drawing).
- Generative RND & ALL Patterns:
- RND: Generates randomized percussive or melodic rhythms of bursts and pauses on the active chain.
- ALL: Distributes a single held note randomly across all loaded chains so that every synthesizer takes its turn in a generative dialogue.
🎚️ 16-Macro Matrix with Deep Parameter Mapping
Tame complex multi-instrument architectures with a centralized macro control deck:
- 16 Assignable Macro Knobs: Group critical parameters across all chains into an accessible 4x4 macro control surface.
- Flexible MAP Mode: A single macro knob can control an unlimited number of destination parameters across any chain's synthesizer, MIDI effect, or audio insert, each with independent minimum and maximum value ranges.
- Full Parameter Integration: Every macro, selector, and mixer control is a first-class node parameter. Modulate them with LFOs and envelopes, record DAW automation, or map them to hardware controllers via MIDI Learn.
🖥️ Rack-in-Row Visual Ergonomics: Full-Height Device Integration
Unlike traditional DAWs that trap complex multi-chain instruments inside tiny, nested sub-windows, Omni seamlessly integrates the Instrument Rack into the track's horizontal device chain:
- Unified Full-Height Cards: The Rack Overview card (Macros + Chain Selector), the selected chain's MIDI FX, its central Instrument, and its Audio FX render as first-class full-height device cards between sleek boundary delimiter brackets. Nothing is squished or clipped vertically.
- Hardware Aesthetic: Features recessed LCD parameter displays, responsive peak meters with level coloration, and channel accent badges matching Omni's modern hardware aesthetic.
- Safe Plugin Hosting: Plugins loaded into chain slots run through Omni's non-blocking loader and project trust gate. Untrusted or missing plugins safely retain their serialized state.
- Full Plugin Delay Compensation (PDC): Omni automatically synchronizes latency across all parallel chains and sleeps silent chains to ensure zero CPU waste.
