MIDIFEATURE(N) LOCAL MIDIFEATURE(N)NAME
midifeature — tclmidi command to control hardware specific features on a
MIDI device
SYNOPSIS
midifeature DevID [device_specific_features]
DESCRIPTION
midifeature is a 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 mididevice(n)
command. The first argument is the device identifier, as returned by a
call to mididevice(n). The remaining arguments are device specific.
Currently, the following features are available:
kernel_timing This feature enable kernel based timing on the interface.
This is the default timing mode on all devices.
smpte_timing This feature is only available on the MQX-32 MIDI inter‐
face. 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.
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 per‐
haps less so. It use is discouraged, and is only used for
driver debugging purposes.
get_smpte This feature is only available on the MQX-32 MIDI inter‐
face when that device is in SMPTE mode. It returns the
current SMPTE time. The time is in the form:
hh:mm:ss:fr:ff
RETURN VALUES
Return values are dependent on the feature type. See the list above for
details.
