Troubleshooting

No sound

Open Audio / MIDI and confirm the intended audio output device is selected and active.
If your interface provides its own ASIO driver, select that driver rather than a generic Windows audio path whenever possible.
Confirm that the intended sound source/bank is loaded and ready.
Check MASTER, STYLE and the relevant PART MIXER faders. Confirm that Mute/Solo states are not hiding the part you want to hear.
If MIDI keys do not trigger sound, confirm that the correct MIDI input device is enabled and that Stage Arranger is receiving notes.
If the device appears unavailable, close another audio application that may be holding it, reopen Audio / MIDI and select the device again.
Confirm that headphones/speakers are connected to the output you actually selected.

Tip: If the interface works in another application but not in Stage Arranger, compare the selected device, sample rate and driver type in both applications.

Audio latency: the sound arrives late

Latency is the delay between pressing a key and hearing the result. On Windows, use the hardware manufacturer's native ASIO driver whenever one is available. Hardware-specific ASIO drivers are generally the preferred path for low-latency music performance.

The audio buffer is the next major control. A larger buffer gives the computer more time to process audio but increases delay. A smaller buffer reduces delay but raises CPU pressure and can cause clicks, pops or dropouts if the system cannot keep up.

At 44.1 or 48 kHz, try 128-256 samples as a practical starting point for live playing.
If you still feel delay and the system is stable, try a smaller buffer.
If you hear crackles or dropouts, raise the buffer until playback is stable.
Close unnecessary heavy background applications and avoid overloaded USB hubs.
For live playing, use wired headphones/speakers rather than Bluetooth monitoring.

Clicks, pops or audio dropouts

Very small buffers, heavy CPU load, USB problems, unstable drivers or demanding plug-ins can all cause glitches. Raise the buffer first. If the problem remains, test the interface directly on another USB port, remove unnecessary USB hubs, close heavy applications and confirm that the interface driver is current.

MIDI works, but the wrong sound or octave is heard

Check RIGHT1/RIGHT2, OTS, octave/transpose and the active Style. For a User Style, open the relevant mixer channel and verify the selected voice and octave correction. Third-party Styles may require manual tuning.

Auto Voice edits disappeared

Edits remain when switching slots in the current style. Changing styles or banks clears unsaved slot memory. Use SAVE STYLE before leaving, or SAVE CONFIG for a complete setup snapshot.

No compressor gain reduction

Check that compression is on, ratio is above 1:1 and input exceeds threshold. Lower threshold for quiet material. Raising Master or Makeup does not raise detector input.

Unexpected octave

Check the selected part’s VOICE OCTAVE separately from UPPER OCTAVE and TRANSPOSE. Auto Voice can recall its own octave.

Accompaniment mix did not save into the style

SAVE STYLE currently writes supported OTS edits. Use SAVE CONFIG for accompaniment mixer changes and local processing.
