"Where's the midi loopback device in the FreeBSD OSS implementation?" - blubee blubeeme

sndiod is intended for Midi on FreeBSD.

ports/sndio

>From pkg-descr:
    Sndio is a small audio and MIDI framework part of the OpenBSD project.
    
    It provides an lightweight audio & MIDI server and a fully documented
    user-space API to access either the server or directly the hardware in
    a uniform way.  Sndio is designed to work for desktop applications,
    but pays special attention to synchronization mechanisms and
    reliability required by music applications.  Reliability through
    simplicity are part of the project goals.

/etc/group ---> _sndio:* ...
/etc/rc.conf.local ---> sndiod_enable="YES"

The rc.conf.local variable is from:
/usr/local/etc/rc.d/sndiod ---> rcvar=sndiod_enable

See also pkg-plist from its port directory

man sndiod(8) is about the sndio MIDI server daemon
