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.

​

DJ master recordings

DJ mode also writes set recordings into Bounces. Press [R] on the DJ tab to start or stop a take. [CTRL+R] opens input recording instead. Each set is a stereo IEEE Float32 32-bit WAV at the actual DJ output rate, named DJ Set YYYY-MM-DD HH-MM-SS.wav. Collisions receive a suffix such as (2). Recordings that approach classic WAV’s size limit continue in numbered files such as Part 2. The DJ recorder always captures Meiji Sampler’s safety-limited post-PerformFX software master. In system-output mode this is the master sent through the software route. In REV7 hardware mode it is the unity-gain sum of the two post-PerformFX deck stems before the physical mixer. Physical EQ, faders, crossfader, microphone or auxiliary input, and hardware master processing are excluded. An interrupted take retains a .partial file for overflow, tap, disk, or finalization failures. Meiji Sampler does not announce or scan that file as a finished bounce. Keep the partial unchanged until you follow the recovery steps.

​

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: 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. The master WAV captures the performed master output, including live PerformFX gestures. Channel exports stay pre-master-FX so stems remain clean for later mixing. 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 video soundtrack uses the same post-PerformFX master audio as the master WAV. Its channel waveforms are still drawn from the pre-master-FX channel captures so the visualizer can show individual channel activity. 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.
