To initiate recording, first arm some tracks by toggling their record buttons, then toggle the global record-enable button on the transport. Recording will begin when you press play. During recording, the timeline darkens and refuses normal input. Regions being captured are colored bright red. The viewport will automatically follow the playhead as the recording progresses. Recording stops when you stop the transport or toggle the global record-button.

Regions are the most common object on the timeline. Each region represents some portion of an audio source placed at some position in time. Since Non-DAW is non-destructive, regions only <b>represent</b> the source--altering a region does not affect the audio source in any way. Deleting a region does not delete the source--as other regions may still refer to it.

Instead of requiring you to duplicate a small region 100 times to achieve a looping effect, Non DAW supports looping directly. First, adjust the region duration to cover the amount of time you would like it to loop for. Then, position the mouse pointer over the first place the loop should repeat (i.e. the first bar line after the start of the region) and hit <tt>L</tt>. This will set the loop point for this region, which will be indicated by two white arrows. At playback, the portion of the region before the loop point will loop for the duration of the region.

<p>
<i>Control Voltage</i> is similar to control voltages generated by analog equipment. Setting the Control Sequence mode to Control Voltage will create a JACK output port whose contents simulate an analogue Control Voltage signal. This mode can be used to control anything that accepts CV style input. Useful targets include the Non-Mixer, and SpiralSynthModular.

<h5 id="n:1.1.12.1.2.">1.1.12.1.2. Control Signal</h5>
<p>
The <i>Control Signal</i> mode uses a signal routing layer on top of the OSC protocol to intelligently and automatically discover and control any module parameter in Non-Mixer. The output of one Control Sequence may be connected to any number of Control Signal inputs available in Non-Mixer.

<p>
Control Signals are more efficient than Control Voltages when a large number of parameters are being automated.

`Ctrl+]` moves the right range cursor (P2) to the position of the playhead.
The edit cursor defines a region to apply an operation to. The edit
cursor is also used to define the region other cursors, such as
Punch and Playback, are created from.
The range cursors can be set individually with the mouse by positioning the
pointer over the desired location and pressing `[` or `]`. Alternatively,
both may be set at once by holding `R` and left-click+dragging the selection

Cursor.
Hitting `Ctrl+Shift+L` sets the playback cursor to the same
dimensions and position as the Edit Cursor.
