Orinj Working with loops

Not Rated Yet

Orinj version 3.0.0

A loop in Orinj is a collection of tracks. These tracks contain short wave files of drum hits and buttons that tell Orinj when to play these drum hits. The tracks also contain effects (e.g., delays, reverbs), volume and pan settings, and other settings. A loop is not very different from a recording session. However, rather than recording audio data and mixing it into a song as you would normally do in a recording session, you can use the loop tracks to arrange existing audio files – of drum hits.

By arranging drum hits on tracks, you will create drum loops. This helps if you do not own a set of real drums or do not know how to play drums. If, for example, you want to build a standard alternating kick and snare drum loop, you will:

  • Set a 4/4 loop;
  • Add an existing kick drum wave file to the first track;
  • Add two kick beats (hits) to that same track on the 1 and 3 of the rhythm;
  • Add an existing snare hit wave file to the second track;
  • Add two snare beats to that second track on the 2 and 4 of the rhythm;
  • Perhaps, add a high hat or other cymbals; and
  • Mix this loop into a single wave file that you can then import and loop into your multitrack session.

Loops are displayed and controlled by the Orinj loop building view. All of what you can do in this view controls either your loop or individual components of your loop, such as tracks, wave files, and effects. To gain a more complete understanding of loops, see also Orinj Working with loop tracks, Orinj Working with loop hits, and Orinj Working with effects.

Create a new loop

To create a new loop, click on File and then on New in the Orinj menu. The current loop, if there is one, will be closed and a new loop will be ready for use. You may be asked to save the current loop, before it is closed.

Save a loop

To save a loop in a file, click on File and then on Save in the Orinj menu. You may be prompted to give a name to the loop.

If you want to save the loop under a name that is different than its current name, click on File and then on Save As in the Orinj menu.

Open an existing loop

To open a loop, click on File and then on Open in the Orinj menu. You will be prompted to browse to your loop. Find the loop file and open it. All loop files have the extension "klp". This extension may be visible, depending on the settings of your computer.

If the loop that you want to open was used recently, it will be listed under File and then Recent in the Orinj menu. You can click on the corresponding menu command to open that file.

A number of ready loops are included in the Orinj installation. These loops reside in the "../loops/" folder of your Orinj installation. These loops are examples for various music styles.

Close the current loop

To close the current loop, click on File and then on Close in the Orinj menu. You may be prompted to save the loop first.

Choose an output device

During playback, Orinj sends all sound to one output device (soundcard). To choose the output device, to which sound data will be sent during playback, click on Loop and then on Output Device in the Orinj menu. You will see the following dialog.

Output device dialog

This dialog lists all available output devices. The "primary sound driver" device is usually the default sound device chosen through your operating system. Select a device in the dialog and click OK.

Set the tempo / time signature

To set the tempo and time signature of your loop, click on Loop and then on Tempo / Time Signature in the Orinj menu. You will see the following dialog.

Tempo and Time Signature dialog

Use this dialog to determine the tempo and time signature of the loop. Unlike in the multitrack session, the time signature of the loop is important. Each track in the loop building view has notches that are determined by the time signature. In 4/4 rhythm, for example, each track will have 16 notches for each of the 16 quarter notes in the beat. As you add drum hits to a track, you can snap these hits to the track notches, which ensures that the hits will be exactly on beat.

See also Orinj Working with sessions for further detail on the Tempo / Time Signature dialog.

Play, stop playback, pause

To play your loop, click on the play button (Play button) in the player toolbar at the bottom of Orinj, or click on Loop and then on Play in the Orinj menu. To play the loop indefinitely, click on the play loop button (Play loop button) in the player toolbar at the bottom of Orinj, or click on Loop and then on Play Loop in the Orinj menu.

To stop playback, click on the stop button (Stop button) in the player toolbar at the bottom of Orinj, or click on Loop and the on Stop in the Orinj menu. Subsequent playback will start from the beginning.

To pause playback, click on the pause button (Pause button) in the player toolbar at the bottom of Orinj, or click on Loop and then on Pause in the Orinj menu. You can then either resume playback or you can stop it.

Fast forwarding, rewinding, and recording are not available in the loop building view.

Mix

To mix your loop to a wave file, click on Loop and then on Mix in the Orinj menu. You will get the Loop Mix Properties dialog shown in the picture below.

Loop mix properties dialog

Use this dialog to specify the sample rate and sampling resolution of the mix. If, for example, you are creating a drum loop for a 16 bit, 44.1 KHz session, you would want to mix the loop to a 16 bit, 44.1 KHz wave file.

Use the dialog also to specify how the remainder of the loop should be handled in the mix. The remainder is the sound data that extends beyond the length of the loop. Suppose for example that you are creating a 4 sec loop that ends with an open high hat. The sound of the open high hat will probably extend beyond 4 seconds. What you will do with this extended loop depends on how you want to use the loop. If the loop is something that will be played over and over in your song, you will probably want to wrap the remainder. The end of the high hat will then sound over the beginning of the loop (it will be wrapped around). If you then insert the resulting wave file in your song and loop it over and over again, the high hat will sound natural. If this loop is something that will be played only once (a drum fill maybe), you can leave the remainder and create a loop that is longer than 4 sec and incorporates all sound data from the high hat.

Click OK in the dialog to mix the loop. Orinj will create a wave file and switch to the single wave view, where this wave will be displayed.

Note that all individual drum hit wave files are recorded with the 16-bit and 44.1 KHz sampling resolution and sampling rate. Orinj will first mix to these sampling resolution and rate and will then convert the mix to the desired sampling resolution and rate. Also, all drum hits are mono waves. However, they are always converted to stereo waves during playback and mixing, so that effects can be applied appropriately.
