[SOLVED] MIDI input timing is not stable on Linux

The timing of MIDI input in Renoise is not stable in the following situation.
It is stable on REAPER.

What should I do?

Environment:

  • OS: Arch Linux x86_64
  • Kernel: 6.6.3-arch1-1
  • WM: sway
  • pipewire 1:1.0.0-1
  • pipewire-jack 1:1.0.0-1

config:

$ grep -v \# ~/.config/pipewire/jack.conf.d/override.conf
jack.properties = {
      node.force-quantum = 144
}
$
$ cpupower frequency-info
analyzing CPU 5:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 5
  CPUs which need to have their frequency coordinated by software: 5
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 800 MHz - 4.30 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 800 MHz and 4.30 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 2.97 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes

Sorry, it was an elementary mistake. Quantize was just turned on.
