"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: https://gist.github.com/c3a212d0071ed78adf4507d16e74305d 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() [1] https://github.com/SpotlightKid/python-rtmidi
