Chapter 10: MIDI Recording 103
MIDI Thru
To monitor MIDI tracks while recording,
enable MIDI Thru. When enabled,
Pro Tools routes MIDI from your control-
lers to the device and channels assigned to
the MIDI track currently record-enabled.
To enable MIDI Thru:
■ Select MIDI > MIDI Thru.
When using MIDI Thru, you should disable
Local Control on your MIDI keyboard con-
troller. Otherwise, your keyboard may re-
ceive double MIDI notes, which can lead to
stuck notes. If unsure how to disable Local
Control for your instrument, refer to the
manufacturer’s documentation.
▲ When MIDI Thru is enabled, System Exclu-
sive events are echoed to the MIDI device as-
signed to the record-enabled track—but only if
the sysex events are smaller than 256 bytes.
MIDI Input Filter
Use the MIDI Input Filter to filter out cer-
tain MIDI messages from your recordings.
The Input Filter can be set to record “all”
messages, “only” the specified messages, or
“all except” the specified messages.
For instance, to filter out polyphonic
aftertouch and System Exclusive data:
1 Choose MIDI > Input Filter.
2 In the MIDI Input Filter dialog, select the
Only option.
3 Make sure the options for Polyphonic Af-
tertouch and System Exclusive are not se-
lected. Leave all other messages selected.
4 Click OK.
When using the Only option, only the
MIDI messages that are selected will be re-
corded. Conversely, when using the All Ex-
cept option, the selected messages will not
be recorded.
