How to use the Sequencer:
Use xa to drop x-tracker.py into the share.

Ensure SYNTH.BAS is still running on the VNC/SPICE screen.

Open a new terminal on hetzner-native and run the bot:
python3 x-tracker.py

Jump into your #ops IRC channel and paste this exact command to test the
timing engine (it's Beethoven's Ode to Joy mapped to our synth keys):

$track E E R T T R E W Q Q W E E W - W . E E R T T R E W Q Q W E W - Q - Q

The bot will acknowledge the lock, and you will hear perfectly paced hardware
audio stream directly out of QEMU, entirely unaffected by any Tailscale
latency!
