If you ever want to run midi(4) out of the giant lock, uncomment MIDI_OUTOFGIANT in midi.h. Confirmed to work for csamidi with WITNESS and INVARIANTS. - midi_info, midi_open and seq_info are now tailqs, allowing arbitrary numbers of devices to be configured. - Do not send an active sensing message to reset midi modules. - Clone /dev/sequencer*. /dev/sequencer0 and /dev/sequencer are generated upon initialization.
