One of the things I was wondering, it seems like
there's no way to make
use of the functionality some instruments have to kill all sounds (panic
button) for all instruments in a session.
"Panic" is a colloquial name for the reaction triggered by the
combination of the MIDI "All notes off" and/or "All sound off" and
"Reset all controllers" messages. Devices and software, which have a
panic function usually react to these MIDI messages as well.
Here's a script using python-rtmidi [1] to send "All sound off" and
"Reset all controllers" on all MIDI channels to all available JACK MIDI
outputs:

import rtmidi
from rtmidi.midiconstants import (ALL_SOUND_OFF, CONTROL_CHANGE,
RESET_ALL_CONTROLLERS)
mo = rtmidi.MidiOut(rtapi=rtmidi.API_UNIX_JACK)
print("Sending AllSoundOff and ResetAllControllers on all channels...")
for portnum, portname in enumerate(mo.get_ports()):
print("Port:", portname)
mo.open_port(portnum)
for channel in range(16):
mo.send_message([CONTROL_CHANGE, ALL_SOUND_OFF, 0])
mo.send_message([CONTROL_CHANGE, RESET_ALL_CONTROLLERS, 0])
mo.close_port()
