Please check if these commands work: firewire-request /dev/fwX read c007dedadada 4 firewire-request /dev/fwX write c007dedadada f100123456789abc In theory, you should be able to write MIDI commands by prefixing them with 00, like this for a note-on: firewire-request /dev/fwX write c007dedadada 00912345 > Turning on the SCS.1d then yields: > firewire_core: created device fw2: GUID 0012600100000000, S400 FFADO had only the 1m's ID, so the driver does not yet know about the 1d.
