Eight columns, eight scenes, sixty-four pads, and a model that fills the empty ones with audio that fits your project: same key, same tempo, same room. A Launchpad-style groovebox with ACE-Step generation built in, running entirely on your Mac.
Set-ready software runs at the venue, on the plane, in the basement, anywhere. OhmsGrid is built like a hardware groovebox should be: launch a clip and it plays. No buffering, no auth check, no “you're offline” modal.
Every pad you launch, every clip the AI generates, every stem you separate is processed on your Mac. No upload step. No cloud rendering queue. No login. The grid works on a plane at 35,000 feet exactly the same way it works at your desk.
OhmsGrid handles audio you imported, audio you generated, project files, and your preferences. None of it is transmitted. The only outbound traffic is the one-time download of the ACE-Step model from a public open-weights mirror, and Ableton Link LAN tempo discovery if you opt into it.
ACE-Step is open-weights. Stems separated via UVR are open-weights too. The clips you bounce out of OhmsGrid carry no platform claim and no per-stream license. Sample them. Sell them. Resample them tomorrow. The app doesn't appear in your release notes unless you put it there.
Columns are instrument categories. Rows are scenes. Each cell is a clip slot you can fill with your own sample or ask the AI to generate for you. Launch a single pad. Or fire an entire row and watch the system play in lockstep: quantized, key-matched, tempo-locked.
Interact with the live offline simulator below. Click empty pads to request ACE-Step to generate audio segments locally. Toggle Play to trigger a synchronized vertical step scan.
Click an empty pad. Type a short prompt (“heavy 808 kick pattern”). Pick a style bubble or two. The model reads your project's key, tempo, and the column's category, then generates a clip that fits. Duration is auto-calculated by column (drums run 2 to 4 bars, pads run 4 to 8). All on device via ACE-Step.
Drop a track into the Separation tab. UVR runs locally. Stems route directly to grid columns (vocals to VX, drums to DR, bass to BS) or save to disk as files. No upload step. No watermarked preview. No platform claim on the stems you extract.
The grid is built for live performance: pads render their waveforms live in canvas at 60fps; FX pads trigger momentarily and snap back; scenes quantize to bar boundaries by default. The same mental model as a Novation Launchpad, without the hardware dependency.
Launchpad-style clip launcher. Each column is a category (Drums, Bass, Lead, Melody, Pad, FX, Vocal, Perc). Each row is a scene. Trigger pads individually or fire whole scenes with quantization.
Browse, search, and drag-drop your own samples by category. Organized by the same column taxonomy as the grid: drums go to drums.
Empty pads auto-fill via ACE-Step. The model picks up project key, tempo, and the column's category. Drums sound like drums, pads sound like pads.
Generate N candidates per empty pad and the app auto-selects the highest-quality result. Audition the rest if you want.
Quick genre/mood tags (Lo-fi, Trap, Ambient, etc.) for AI prompts. Click two or three; the model reads them as additive style hints.
Bundled UVR runtime separates any clip into vocals, drums, bass, and instrumental. Written directly to grid columns or to disk.
Per-column volume, pan, mute, and solo. A master signal scope so you can see what's clipping. The same surface a Launchpad-trained performer would expect.
Every pad renders its waveform live, in canvas, at 60fps. Momentary FX pads. Performance-grade UI built for set-ready use, not just studio mouse work.
