Error messages

Meiji Sampler surfaces many failures as short UI status messages, confirmations, or logged operation errors rather than one centralized error catalog. This page groups the important user-facing error classes so you know where to look next.

​

Common failure categories

​

File recovery behavior

When a state or project file is corrupt, Meiji Sampler may attempt backup recovery from a .bak file. That is usually the first recovery path rather than an immediate hard failure.

​

Bounce/export errors

Bounce failures usually come from:

• invalid output path
• file creation failure
• video generation cancellation or downstream failure

Check:

• the target folder exists and is writable
• export settings are sensible
• there is enough disk space

​

Recording/input errors

Input failures typically mean:

• no usable input device is available
• the selected device or channel is invalid
• the device changed after the app opened

​

Config save failures

Some features save preferences immediately after changes, including:

• MIDI mappings
• PerformFX bank/profile changes
• settings updates

If these saves fail, your change may work temporarily in-session but not persist after restart.
