Monitoring Options

Audio input monitoring behavior is set in the Sequencer's menu: Options > Monitor.

The options are:

  • Off - Never monitor the input
  • Auto - The default; whenever a track is selected, the input will be passed through to the output.
  • Record - Monitor a track's input only when the track is recording
  • Manual - When this is selected, a button appears on audio tracks which lets you manually control the monitoring for each track.

Track Mute vs. Mixer Mute

As the above image shows, the mute buttons on the track header and on the mixer strip do two different things. Muting a track (from the track header) blocks the output from existing parts on that track. This doesn't affect input monitoring, which is controlled separately. The mixer mute button mutes everything, including input monitoring and parts on the track.

Multi-Sample vs. Single-Sample Parts

There are two types of audio parts in energyXT2, which can be confusing. The differences will be outlined below.

Single-Sample Parts

Recording new audio or dragging a wav/aiff/mp3 file to an audio track will create a single-sample audio part.

You can select a range of the audio and do various processing.

Multi-Sample Parts

Multi-sample parts are created by gluing two or more single-sample parts together. The advantage of a multi-sample part is that you can make ghost copies of it. Within the part, you can rearrange, delete, split, and duplicate the slices, and reverse or stretch each slice separately, and the changes will apply to all ghost copies. You can also save the part as an .xtc clip for later re-use.

Copying a slice from a multi-sample part and pasting it to a blank area of an audio track will create a single-sample part.

Audio Recording

First, make sure the correct input is connected to the track you are recording to. By default, audio tracks are connected to the Audio In component, but you can change this in the Object Bar (click on the track header and look under “Input”). Input connections can also be made in the Modular area.

Audio will be recorded to any tracks that are selected. Use Ctrl-Click to select or unselect multiple tracks. You can also use Shift-Click to select a range of tracks.

You can choose to record in Mono or Stereo, using the “Record” dropdown in the Object Bar.

Recording over an existing part does not overwrite it, but instead creates a new part on top of it.

Punch In/Out

You can start and stop recording while XT2 is playing, either by clicking the Record button, using the keyboard shortcut (R by default), or sending the mapped MIDI CC (see Controller Map).

Doing an automatic punch in/out is possible, but slightly tricky.

Audio Editing

Fade In/Out, Crossfade Parts

Each single-sample part and each sample within a multi-sample part can have a non-destructive fade-in and fade-out applied. Fades are set in the Object Bar in units of milliseconds.

To apply a crossfade to two overlapping items, select them and press Shift X. This adjusts the fade-in and fade-out times to the size of the overlap. The Crossfade command is also available in the main Sequencer menu under Part > Process > Crossfade, as well as in the part right-click menu.

Slicing/Splitting Parts

Single-sample parts can be sliced automatically, either according to the snap size (Beatslice) or by detecting transients (Autoslice).

To split a part by hand, use Alt right-click to split at the mouse pointer position, or Ctrl K to split at the play cursor position.

To combine the sliced parts into one multi-sample part, select them all and Glue them with Ctrl G.

You can also split samples within a multi-sample part.

Destructive Editing

Destructive audio editing is done on single-sample parts only (for the moment). Some processing can be done on a whole audio part, or you can select a range of it and process only that range. For every edit, a copy of the audio file is made. When you're done editing, you can remove the intermediate files from the Audio Pool.

Part Processing

When no audio range selection is made, the following processes apply to the entire selected part:

Normalize
Amplifies the part so that it peaks at 0 dB
Reverse
Reverses the part in time
Fade In
Creates a fade-in over the whole part
Fade Out
Creates a fade-out over the whole part
Beatslice & Autoslice
Non-destructively slices the part; see Slicing/Splitting Parts above

Range Processing

To select a range of an audio part, open the in-track or popup editor, and drag across the waveform with the mouse. The selection obeys the snap settings, and you can adjust the selection after making it by dragging the edges.

To process a selected range, right-click and look in the Process menu:

Normalize
Amplifies the selected area so that it peaks at 0 dB
Delete
Silences the selected area
Cut
Removes the selected area, shortening the sample. The removed area can then be pasted with Ctrl V.
Trim
Silences the area outside the selection
Reverse
Reverses the selection in time
Fade In
Creates a fade-in over the selected area
Fade Out
Creates a fade-out over the selected area

You can also cut, copy and paste the selection with keyboard shortcuts (Ctrl X / Ctrl C / Ctrl V by default). The selection is pasted at the mouse cursor location, either as a new audio part, a new sample in a multi-sample part, or as a destructive addition to a single-sample part.
