​
Export as audio + video

Bouncing prints your arrangement to files on disk.

​
What the bounce flow can persist

Current bounce settings include:
  • export master
  • export channels
  • export WAV (with configurable bit depth)
  • generate video
  • open folder after export

​
Output location

Bounces are written to:
  • macOS: ~/Documents/Meiji Sampler/Bounces/
  • Windows: Documents\Meiji Sampler\Bounces\
  • Linux: $XDG_DOCUMENTS_DIR/Meiji Sampler/Bounces/ if set, otherwise ~/Meiji Sampler/Bounces/
The app generates date-and-time-based filenames and can create channel-specific files when exporting stems/channels separately.

​
WAV bit depth

The bounce modal lets you choose the bit depth for exported WAV files. When WAV Audio is enabled, use Left/Right on the WAV Audio row to cycle through:
OptionFormatUse case
16-bitSigned integerSmallest files. Standard for final distribution and casual listening.
24-bit (default)Signed integerGood balance of fidelity and file size. Preferred for handoff to a DAW or archiving.
32-bit floatIEEE 754Lossless from the engine’s internal processing. Use when you need maximum dynamic range for post-production.
Meiji Sampler processes audio internally at 32-bit float precision. Choosing 24-bit or 32-bit float preserves more of that precision in the exported file. The setting persists across sessions.

​
Good default export

For most users:
  • export master: on
  • export channels: off
  • export WAV: on (24-bit)
  • generate video: off

​
Exporting stems (channel export)

When Export Channels is enabled, each channel is rendered as a separate WAV file alongside (or instead of) the master. Files are named by channel number and any assigned channel name. Use channel export when you want:
  • a handoff into a DAW for further production
  • separate stems for later mixing or mastering
  • to archive the session in a modular format you can remix later
Channel export can be combined with master export (both get written) or used alone. If you only need stems and don’t want a mixed master, turn off Export Master and enable Export Channels.

​
MP4 visualizer

When MP4 Visualizer is enabled, Meiji Sampler renders a 1080×1080 video alongside the audio. No external tools like ffmpeg are required — encoding is built in. What the video includes:
  • a scrolling waveform for the full duration of the bounce
  • channels color-coded by sample type, matching the mixer output history display
  • CRT-style post-processing (screen curvature, bloom, scanline flicker, subtle burn-in)
  • a spinning Meiji Sampler logo in dot-matrix style
  • H.264 video at 6 Mbps + AAC audio at 192 kbps
The format is square (1080×1080) and intended for sharing on Instagram or other social platforms. The video is written to the same output folder as the WAV files. Video rendering is background work — Meiji Sampler stays usable while it encodes.
Meiji Sampler supports several levels of hardware GPU acceleration.To confirm hardware acceleration enabled, check Settings → General.Exporting video is a slow but worthwhile process. Be patient and let the export complete.
