Settings
Open the Settings tab with, or by pressing Tab to cycle through tabs. Settings uses a two-pane layout: a sidebar listing categories on the left and a content pane showing fields on the right.
Project category
The Project category is selected by default when you open Settings. It gives you inline access to all project operations without leaving the tab.Project info
When a project has been saved, the tab shows:- Name — the current project name, with a yellow dot when unsaved changes exist
- Location — the file path on disk (home directory shortened to
~)
Project actions
Paths
The bottom of the Project category shows four directory shortcuts. PressEnter on any path to open it in your OS file manager.
Tempo category
The Tempo category holds the project playback tempo editor. Meiji Sampler infers the session BPM from the first recorded loop; this category lets you override that effective tempo without changing pitch.
The Tempo editor requires at least one recorded loop to establish a timing source unless you set BPM manually first. Until then the page shows
Awaiting 1st loop. Range is available before recording and applies the next time a first loop establishes project tempo. Pressing [R] before the first loop opens First Loop Setup, which defaults to Fixed mode at 90.00 BPM, Quantize OFF, 1 BAR Length, 4 BEATS Count-in, and click REC + PLAY; Fixed mode stops recording automatically at the selected Length, and [ENTER] can end the take early without shortening the loop or starting playback before the fixed interval arrives. Select Mode: AUTO TEMPO when you want the completed take to define tempo by its ending; Auto keeps Length as AUTO while still applying the dialog’s Quantize, Count-in, and Click choices, then continues directly into overdub. Press [ESC] to cancel without arming. A pad or chop key that starts a record count-in plays immediately. Hits during the final count-in beat are recorded at 0:00; earlier hits are consumed as unrecorded start-signal updates when REC begins. The metronome click is routed outside bounce, resample, and internal capture paths, so it guides recording without printing into the sampled audio.
Audio category
Audio section
Smaller buffers reduce latency and increase CPU sensitivity. The millisecond value is calculated from the selected buffer size and sample rate. Audio host, output device, Stereo Channels, buffer size, and sample rate changes are saved immediately, then prompt you when you exit Settings to [Apply Now] or keep the current engine running until [Next Launch]. Stretch Loops on Load affects pad loop setup only; it does not restart the audio engine.
Quantization section
MIDI section
When enabled, Meiji Sampler responds to MIDI transport messages (start, stop, continue).
DJ category
The DJ category stores the pitch-range default for the next track load on either deck, and the DJ output stream’s own buffer size.
Changing Pitch Range does not change the pitch range, pitch, or physical-fader interpretation of either active deck. When you later load a track on deck A or B, that deck adopts the saved default and returns to neutral pitch; the other deck is unchanged. Each active deck keeps its own range. Use
[P] in DJ Mode or the Pioneer DDJ-REV7 TEMPO RANGE button to cycle an active deck’s range and save one global default for the next track load on either deck.
Buffer Size is independent of Audio → Buffer Size. The DJ deck path renders a frame at a time and drains every pending control per frame, so the DJ stream defaults to 128 where the sampler defaults to 256 — about 2.9 ms less control-to-speaker delay at 44100 Hz. Choose 64 for the tightest deck, or climb to 256 or higher as a crackle fallback. There is no audio engine restart prompt; the size applies the next time DJ audio opens, on re-entering the DJ tab or on the next controller hardware attach.
[←] reverses a value. [→] and [L] advance it. [↑/↓] moves between the two fields. [H] returns to the Settings sidebar without changing the value. See DJ Mode and Keyboard Shortcuts.
