## What is D9 Metronome?

Whether you’re keeping a steady beat for daily practice, building up your speed, or mapping out entire songs with your band, D9 Metronome gives you all the tools you need in one clean, easy-to-use app.

From simple clicks to deep groove customization, D9 Metronome adjusts to the way you play.

Key Features:
Intuitive Controls: Spin the tactile 3D wheel to quickly dial in your BPM (from 10 to 400 BPM), use Tap Tempo, or check classic tempo markings like Adagio, Allegro, and Presto.

Flexible Rhythms & Grooves: Go far beyond basic beats. Play with time signatures up to 25 beats per measure, custom subdivisions (including shuffles, gallops, and syncopations), nested tuplets, polyrhythms, and per-beat muting.

Smart Practice Tools:
Speed Trainer: Automatically ramps up the BPM over time to build your speed and accuracy.
Bar Muting (Rhythm Trainer): Drops the click out for selected bars to test and train your internal clock.
Song Automation & Setlists: Build complete arrangements! Chain together segments with custom time signatures, tempo changes, and gradual slow-downs (ritenuto) for live gigs or rehearsals.

SoundLab & Voice Counting: Choose from acoustic drums, woodblocks, synthetic ticks, or human voice counting (male and female). You can even design and tweak your own custom click sounds using the built-in synthesizer!

Visual & Haptic Cues: Practice silently using the smooth visual pendulum, camera LED flash pulses, or device haptics/vibrations.

Expanded View for Larger Screens: Switch to wide views on tablets or desktop to see a massive beat counter, bar numbers, and automation progress at a glance.

Play Together with Easy Sync:
Global Sync: Join bandmates anywhere in the world using a simple 6-digit code.
Ableton Link & MIDI: Jam over local Wi-Fi with Ableton Link or connect your favorite Bluetooth MIDI pedals and hardware.

Save Everything: Save your complete setups, sound tweaks, and song setlists as presets so you can instantly recall them anytime.
