Recording

Cantabile supports audio and MIDI recording, including automatic recording where the recorder starts and stops automatically as you play. Cantabile can be left in auto record mode and it will capture everything you play.

This video walkthrough also demonstrates working with the recorder.

Cantabile Solo and Cantabile Performer Only.

Selecting what to Record

The recorder captures audio and MIDI data from a set of input and/or output ports that you select. For example you might choose to record incoming MIDI from your main keyboard as well as audio sent to the speakers.

To select the ports that should be recorded, from the View menu, choose "Recorder Ports". This will show a small panel at the bottom of the recordings list where you can choose which ports to record.

Recorder Ports

Note that a port doesn't need to be connected to a physical device to record it. This can be handy to record signals from inside the song - simply create an audio or MIDI output port, leave it disconnected, setup a route to send the signal to be recorded and then select the port in the recording ports list.

Manual Recording

To start recording, click the Record button on the main toolbar, use the shortcut key ('R' by default) or choose the "Record" command from the "Control" menu.

Recording will continue until you stop the recording by pressing the Record button again. Once the recording has completed, a new entry will appear in the recording list.

Recordings with a duration of less than 5 seconds will be discarded. You can adjust this duration in Recording Options.

Automatic Recording

To enable automatic recording, from the Control menu choose "Auto Record", or right click on the Record button on the main toolbar and choose "Auto Record".

When auto-record is enabled, the small indicator to the bottom right of the Record button on the main toolbar will light up.

Record Button

For a port to be monitored for activity, it must be both selected for recording and the type of port must be enabled in Recording Options. By default only audio and MIDI input ports are enabled. To enable automatic recording for output ports you must enable those port types in Options.

Auto record will stop recording after 5 second of silence. When monitoring audio ports, there is a noise threshold setting that can be used if ambient noise is triggering the audio recorder. Both of these settings can be adjusted in Recording Options.

Recording Files

Each recording will be saved as one MIDI file and one Audio file (unless no ports of a particular type are enabled).

For MIDI files each port selected for recording will be written to a separate MIDI track. The track will be named using the port name.

For Audio files each port will be written as a consecutivie set of channels. For example, if you have two stereo ports selected the resulting wave file will have four channels.

Pinned and Unpinned Recordings

In the list of recordings, each recording has a "pin". Unpinned recordings will be deleted after 7 days (adjustable in Options). Pinned recordings are never automatically deleted.

By default all recordings are pinned and will be kept indefinitely. In Recording Options, you can choose to not pin new recordings. In this case all recordings will eventually be automatically deleted - unless you manually pin them.

Working with Recordings

The recordings list shows a list of all previous recordings. You can use this list manage your recordings. The right click context menu includes commands to rename, delete, re-order and launch Windows Explorer with the recording selected.

There are also commands to delete all unpinned recordings as well as to clear the list without deleting recordings.

Working with Recordings

Recording Filenames and Locations

You can change where recordings are saved and the name of recording files in Options.

Recording Options

Note that the recording list is independent of the loaded song file and is saved in a special file in the recording folder. If you change the recording folder, a new list is loaded. By using multiple recording folders you can manage multiple sets of recordings.

MIDI Time Format Options

When recording MIDI, several different time formats are available:

Realtime (Compatible)

This is the default recording format that is most compatible with other software. It records in real-time (ie: each event is timestamped with millisecond accuracy). Tempo and time-signature information isn't captured in this mode.

Realtime (SMPTE)

This format is very similar to Realtime (Compatible) except the file is marked as SMPTE time format. This is a more correct format for this type of recording but some software programs don't support it.

Musical (Relative) and Musical (Absolute)

In these formats events are timestamped using musical time format.

This format is best for importing into other software programs where maintaining correct musical time is more important than millisecond accuracy. In this format the tempo and time signature of Cantabile's master transport is also recorded (even if it changes during the recording).

In "relative" mode events will be timestamped such that the recording starts just before the first recorded events. In "absolute" mode events will be timestamped using the exact time of the master transport.

To better understand the difference between relative and absolute modes, consider this scenario: suppose a recording is started when the current master transport is at bar 50 (perhaps because the metronome has been running for a while).

  • In absolute mode, the recording would have 50 bars of silence at the start.

  • In relative mode, the recorded events would be at the start of the recording.

Note that the musical recording formats require a running master transport. If the master transport isn't playing when the recording starts, the recorder will automatically start it (if it can). Similarly, if the master transport stops while a recording is in progress, the recording will also stop.

Bindings

The recorder can be externally controlled using Bindings.

ie: you can assign buttons on your keyboard to start/stop recording, enable/disable automatic recording, pin/unpin the last recording etc...
