Tap Tempo 2

Tap the Stream Deck key to calculate BPM in real-time. Long-press to open a companion browser page with a full tempo display and note duration table, updated live via WebSocket. Designed for audio producers, sound designers, and mix engineers who need tempo-synced timing values in milliseconds.

How it works

1. Tap the key — each press registers a tap. BPM is calculated from the average interval between taps (up to 8 taps buffered).

2. Key icon updates — the Stream Deck key shows the current BPM with an SVG-rendered display.

3. Long-press the key (hold 1 second) — opens the companion page in your default browser.

4. Companion page — connects to a local WebSocket server run by the plugin. Taps from either the key or the browser page are synced bidirectionally.

5. Auto-reset — the tap buffer resets after a configurable period of inactivity (default 5 seconds).

Features

- Real-time BPM on the Stream Deck key (SVG rendering)

- Companion browser page with note duration table (whole, dotted half, half, quarter, eighth, sixteenth + triplets)

- Click any table row to copy the duration in milliseconds

- Preset BPM buttons (60, 90, 112, 120, 140, 160)

- Manual BPM entry via input field

- Keyboard support on the browser page (Space / Enter to tap)

- Bidirectional sync — tap on the key or the page, both update

- Connection status indicator on the browser page

- Configurable auto-reset timer (3s to 60s, or never)

- Configurable WebSocket port (advanced)

- Auto-reconnect if the plugin restarts

- Cross-platform: macOS and Windows

Port

The plugin runs a local WebSocket server on port 9876 by default. If this conflicts with another service, change the port in the Advanced section of the Property Inspector. A Stream Deck restart is required after changing the port.
