Description
**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.
