The visualizer shows MIDI events as they occur, displays them on a piano roll, and tracks statistics. This helps you understand exactly what's flowing through your routes.

Route Statistics

Every route displays:

• Messages/sec — Current throughput
• Total messages — Cumulative since route creation
• Latency — Processing time (typically <1ms)
• Last activity — Timestamp of most recent message

Access via:

• Dashboard — Stats on each route card
• Route Editor — Detailed stats panel
• Flow Graph — Hover over edges

Activity Monitor

Tools → Activity Monitor shows:

• Real-time activity across all routes
• Message type breakdown (notes, CC, clock, etc.)
• Per-device throughput
• System load

Activity Graph

• Last 60 seconds of activity
• Color-coded by message type
• Spikes indicate high activity periods

MIDI Monitor

Tools → MIDI Monitor shows raw MIDI messages:

[10:23:45.123] Ch1 NoteOn  60 vel=100
[10:23:45.256] Ch1 NoteOff 60 vel=0
[10:23:45.890] Ch1 CC      1  val=64

Filters:

• Message type (notes, CC, etc.)
• Channel
• Source/Destination

Use for:

• Debugging routing issues
• Understanding what's actually being sent
• Verifying transforms work correctly

Event Visualizer

Tools → Event Visualizer shows:

• Piano roll of note events
• Timeline of CC changes
• Velocity visualization
• Real-time scroll as you play

Interactive:

• Click event for details
• Zoom in/out on timeline
• Filter by channel

Performance Dashboard

Settings → Performance shows:

• CPU usage
• Memory usage
• Thread latency
• Script execution time

Alerts:

• High CPU warning (>80%)
• Memory pressure warning
• Latency spikes

Statistics Export

Export routing stats for analysis:

1. Settings → Statistics
2. Export → Choose format (CSV, JSON)
3. Includes all route stats, timestamps, message counts

Use for:

• Performance analysis
• Troubleshooting
• Session logs

Latency Tracking

Monitor latency per route:

• Input → Output total time
• Per-transform breakdown
• Script execution time

Typical latencies:

• Empty route: <0.5ms
• Route with transforms: 0.5-2ms
• Route with scripts: 1-5ms

High Latency

If latency >10ms, check:

• Script complexity
• Number of transforms
• CPU load
• Background processes

Message Type Breakdown

See what's flowing through each route:

• Note On/Off count
• CC messages by number
• Pitch bend
• Program changes
• Clock ticks

Access: Route Editor → Statistics → Message Types

Troubleshooting Mode

Settings → Advanced → Troubleshooting Mode

Enables:

• Detailed logging
• Step-by-step route execution traces
• Transform input/output capture
• Performance profiling

Warning: Increases CPU usage. Disable for live performance.

Best Practices

• Monitor during setup — Verify routing works correctly
• Disable for performance — Turn off heavy monitoring during shows
• Export stats — Keep logs for troubleshooting later
• Watch latency — Keep routes under 5ms for live play
