About this app

**Pro Metronome — A Precision Metronome for Practice, Rehearsal, and Stage** Pro Metronome combines a sample-accurate click engine, real-time chromatic tuner, structured training tools, setlist playback, and external MIDI control in one focused app for musicians. The metronome is built on a native C++ audio rendering pipeline using Core Audio. Beats are calculated in the audio render thread instead of relying on UI timers, so the click stays stable during long practice sessions, rehearsals, and live use. — Precision Metronome — • Sample-accurate timing with no timer drift • BPM control with nudges, long-press adjustment, and TAP tempo • Rich subdivision patterns for triplets, sixteenths, syncopation, dotted figures, and rest-based rhythms • Per-beat accent control: strong, medium, or weak • Multiple synthesized click sounds, generated in DSP for immediate response • Custom Strings for Tuner * The lowest note for custom tuning can be set to A0. — MIDI Control — Control the metronome without touching the screen: • Bluetooth MIDI support for compatible pedals, controllers, and interfaces • Bonjour network MIDI support for hosts on the same local network • MIDI channel filtering: all channels or CH 1–16 • Learnable mappings for play/stop, start, stop, tap tempo, tempo up/down, absolute tempo via CC, previous song, and next song • Works on the main metronome screen, inside training playback, and during setlist playback Tempo changes are context-aware: MIDI tempo commands update the current metronome preset on the main screen, update the current song during setlist playback, and are ignored during training playback when the training tempo is fixed. — Training & Setlists — Build practice sessions that move with you: • Training mode for structured tempo work and repeatable practice routines • Setlists for saving songs with their own tempo, meter, rhythm pattern, accents, and sound • Previous/next song control for hands-free rehearsal or live performance • Song navigation through on-screen controls or mapped MIDI commands — Built-in Tuner — The chromatic tuner uses YIN pitch detection for fast, stable pitch tracking. It works for guitar, bass, piano, strings, brass, woodwinds, and voice, making it easy to tune before practice without switching apps. — Features Real Players Need — • Left / Center / Right channel output for practice, headphones, and monitoring • Background playback for long sessions • Lock-screen and remote controls • Bar counter for loop practice and long passages • Dark, Light, and System appearance • Keep-screen-on option for rehearsal and stage use • English and Chinese interface support Pro Metronome is built for musicians who treat practice time as quality time.
