.Sh NAME
.Nm midifeature
.Nd "tclmidi command to control hardware specific features on a MIDI device"
.Sh SYNOPSIS
.Nm
DevID
.Op device_specific_features
.Sh DESCRIPTION
.Nm
is a
.Xr tclmidi 1
command that
allows you to control features available only on some \%MIDI hardware
interfaces.
The ability to control features common to all \%MIDI interfaces is
done with the
.Xr mididevice n
command.
The first argument is the device identifier, as returned by a call
to
.Xr mididevice n .
The remaining arguments are device specific.
.Pp
Currently, the following features are available:
.Bl -tag -width mpu401_timing
.It kernel_timing
This feature enable kernel based timing on the interface.
This is the default timing mode on all devices.
.It smpte_timing
This feature is only available on the MQX-32 \%MIDI interface.
It enables an external timing mode based on a \%SMPTE tape.
The device will follow the SMPTE tape times, even if the tape
is rewound, or fast-forwarded.
.It mpu401_timing
This feature is available on all fully MPU401 compatible boards.
It puts the board in intelligent mode and uses it as a timing
source.
Due to driver implementation details, it really is no more accurate
than kernel_timing, and perhaps less so.
It use is discouraged, and is only used for driver debugging purposes.
.It get_smpte
This feature is only available on the MQX-32 \%MIDI interface when
that device is in SMPTE mode.
It returns the current SMPTE time.
The time is in the form:
hh:mm:ss:fr:ff
.El
.Sh RETURN VALUES
Return values are dependent on the feature type.
See the list above for details.
