Setup checklist
Standalone mode
| Check | Pass condition | Action if failed |
|---|---|---|
| Audio device | The correct output device is selected. | SETUP > Open Device Panel, choose output, refresh, then test again. |
| MIDI input | Controller appears and is enabled if needed. | Enable the controller in the device panel or OS MIDI setup. |
| Sample rate and buffer | Stable playback without crackles. | Use a safer buffer size; avoid overloaded sample rates on weak hardware. |
| Master output | Meters move and Master Out is not at silence. | Raise Master Out and track gain gradually. |
| Sound engine | Synthetic or Hybrid plays without requiring an imported bank. | Switch to Synthetic for initial diagnosis. |
Plug-in and DAW mode
| Check | Pass condition | Action if failed |
|---|---|---|
| Plug-in loaded | The VST3 appears on an appropriate instrument and MIDI track. | Rescan plug-ins or confirm the VST3 install path. |
| Track monitoring | The DAW track can output audio. | Enable monitoring or route the track to the master bus. |
| Host sync | Tempo follows the DAW when Host Sync is on. | Start the DAW transport and confirm project tempo. |
| MIDI and audio input | ENGINE receives the intended source. | Route input to the plug-in track; arm the track if the DAW requires it. |
| Bounce and export | The DAW captures the plug-in output. | Use the DAW’s bounce and export and render command unless your build exposes a dedicated export command. |
Symptom checklist
| Symptom | Likely cause | Fix path |
|---|---|---|
| No sound after generation | Muted and disabled mix, wrong output, low gain, or missing audio route. | Check mix enable and arm, Mute and Solo, track gain, Master Out, audio device and DAW routing, then switch to Synthetic. |
| Only some mixes play | Solo and mute state or disabled mix strip. | Clear solo and mute or enable the intended mix strip. |
| Samples do not play | Soundbank missing, registry stale, or mapping failure. | LAB > Verify Installed Banks; rebuild registry; use Hybrid and Synthetic while fixing the bank. |
| Engine buttons are locked | Workflow stage is incomplete. | Capture before analyzing; analyze before Brain generation; generate source before full-track source-dependent actions. |
| Full-track build fails | Missing source material or invalid groove profile. | Generate Mix A to Mix E first, choose current and selected mix source, or complete groove profile. |
| ARRANGE waveform missing | Render and cache not available. | Use Render Selected or Render Dirty; confirm soundbank availability if audio render is required. |
| Imported bank warns | Unknown license, missing checksum, missing samples, or mapping issue. | Do not use for release; review source and license; replace missing files; verify again. |
| Private model unavailable or not armed | The model is not downloaded, not verified, missing an adapter, missing a runtime dependency, or not armed. | Open LAB > Private Models, select the model, complete Download / Install, run Verify and Smoke Test, then ARM MODEL. If the status lists a missing runtime or dependency, install that requirement and refresh. |
| Timing feels too loose | Humanize and swing and density and pocket settings too strong. | Reduce Humanize and Swing, reset timing, or use Groove Lock after a good map. |
| Output distorts | Too much gain or FX and bus drive. | Lower track gain, FX wet amounts, Drive and Bus, Master Out; keep Limiter enabled. |
| Shortcuts fail | Keyboard focus is inside a field or the host. | Click the editor background and grid and try again. |
Support handoff information
When contacting support or preparing an internal issue report, collect the information below. Do not send private source code, licensed third-party samples, or protected research files unless specifically authorized by your support agreement.
| Information | Why support needs it |
|---|---|
| Product version | Confirms the exact build and feature set. |
| Operating system and DAW | Separates standalone, plug-in, and host-specific issues. |
| Standalone or VST3 mode | Device ownership and routing differ. |
| Sound engine mode | Synthetic, Samples, and Hybrid diagnose different layers. |
| Active soundbank and verification status | Identifies missing bank, mapping, or licensing problems. |
| Selected private model and runtime status | Identifies whether the selected model is downloaded, verified, smoke-tested, armed, and connected to the required adapter or runtime. |
| Exact page and button state | Shows whether stage gating or a failed prerequisite is involved. |
| Visible status message | IUS DX-1 status text often states the blocking condition. |
| Steps to reproduce | Allows the issue to be tested reliably. |
Private model troubleshooting
| Model state | Meaning | Customer action |
|---|---|---|
| Available online | The catalog entry is visible and can be downloaded or imported. | Select it in LAB and use Download / Install, or add your own online/local model. |
| Not installed | The model files are not present locally. | Download the model, import a local folder, or choose another installed model. |
| Verify required | The files are present but have not been checked. | Run Verify and review any checksum, manifest or file warnings. |
| Smoke test required | The model is installed but the adapter/runtime has not been tested. | Run Smoke Test. Install any missing adapter, Python package, sidecar runtime or hardware dependency named in the status message. |
| Not armed | The model is selected but generation is not routed to it. | Press ARM MODEL and confirm the right-side status says Armed. |
| Runtime error | The model started to load or run but a technical dependency failed. | Copy Diagnostics and check the missing dependency, model path, adapter, Python runtime or GPU/CPU requirement. |
Emergency audio reset
- Press STOP.
- Press PANIC if notes or playback appear stuck.
- Lower Master Out and track gains.
- Disable extreme FX or return Dry and Wet controls to conservative positions.
- Turn off solo and mute states unless intentionally used.
- Switch to Synthetic engine to verify the core output path.
- In standalone mode, reset the audio device. In plug-in mode, use the DAW device and routing preferences.
