Audio setup

Audio setup is the only technical hurdle you should solve before making your first beat.

​
Output device

Start with the system default output device unless you already know you need something else. In Settings, Meiji Sampler exposes:
  • audio host
  • output device
  • Stereo Channels
  • buffer size
  • sample rate
  • input device
  • input channel

​
Buffer size

The sampler defaults to 256 frames. Smaller buffers give the audio engine more frequent opportunities to output a new hit, but leave less time to finish each batch of audio. Settings labels these values as samples and shows the duration at the selected sample rate. That duration covers one audio buffer. It does not measure the complete delay from pressing a key to hearing a speaker, which also includes the keyboard, terminal, driver, and output device. For finger drumming, use wired headphones or speakers, try 128, then test 64 with the effects and recording workload you actually use. If you hear crackles or dropouts, move up one buffer size. Bluetooth output can add substantial delay independently of this setting. DJ mode has its own buffer setting, which defaults to 128. See Settings.

​
Sample rate

Available sample rates:
  • 44100 Hz
  • 48000 Hz
  • 88200 Hz
  • 96000 Hz
Recommended starting point:
  • 44100 Hz for most users
  • 48000 Hz if it matches the rest of your setup
Higher rates use more CPU. If playback is unstable, increase your buffer size before reaching for a lower sample rate. At a fixed buffer size, a higher sample rate makes each buffer shorter. Match your interface and the rest of your setup first, then tune buffer size; changing to 44100 Hz by itself is not a latency fix. When you change the audio host, output device, buffer size, or sample rate, Meiji Sampler saves the preference and asks whether to restart the audio engine when you exit Settings. Choose [Apply Now] to use the new settings immediately, or [Next Launch] to keep the current engine running until you reopen the app.

​
Linux audio hosts

On Linux, the audio host can be:
  • Auto
  • ALSA
  • JACK
If Auto is unstable, try ALSA. If you already run a JACK setup, use JACK.

​
Input setup

If you want to sample external audio or use the recording feature:
  1. choose the correct input device in Settings
  2. select the input channel or stereo pair you want to record
  3. test monitoring before starting a real take

Next step

Continue to Make Some Noise. If hits still feel late, follow High Latency.
