Orinj Working with session blocks

Orinj version 4.0.0

In the Orinj multitrack session, a wave will appear as a block inside a track, such as the one in the picture below.

An example wave in Orinj

This block displays the actual wave data, with peaks and troughs that align with the time in the Orinj time line. The block may display the full wave or, if you cut out portions of the wave as explained below, only a portion of the wave.

A loop file will appear similar to a wave. Orinj mixes loop files to wave files when displaying and using the loop in the session.

A MIDI file will appear as a similar block, but instead of displaying the wave peaks and troughs, it will show the MIDI notes.

An example MIDI file

For the most part, when working with wave files and MIDI in the multitrack session view in Orinj, you will use commands under Wave in the Orinj menu. What you can do with these commands is described below.

Record wave files

For information on how to record waves, see Orinj Working with sessions or Orinj Working with session tracks.

This version of Orinj does not allow recording of MIDI files.

Loop files cannot be recorded. They are built in the Orinj loop building view.

Insert wave files, MIDI files, or loop files

To insert an existing wave file, MIDI file, or loop file from your hard drive into your session, first select the track in which you want to insert the file by clicking on that track. Click where you want your file to be inserted. Wave files and MIDI files are always inserted at the position of the play cursor (the vertical yellow line).

To insert the file, click on Track and then on Insert From File in the Orinj menu. You will be prompted to browse to the file that you wish to insert. Find the file and open it.

The wave files that you insert in your session must have the same format as the session. If Orinj encounters a file that has a different audio format, it will attempt to convert it. Orinj will create a new file with the proper audio format and will insert that file instead. The original file will not be changed.

If you try to insert an AIF file, AU file, or a non-PCM wave file (such as A-law and U-law compressed wave files), Orinj will attempt to convert this file to a PCM file. A new file will be created and the original file will not be changed.

Mute blocks

To mute a wave, MIDI, or loop block, click on the block to select it and then click on Block and then on Mute in the Orinj menu. If you want to mute the whole track, see Orinj Working with session tracks.

Fade the ends of blocks

If you cut portions of wave or loop blocks, you may end up cutting the audio data at a place where the audio signal wave is not zero. When playing the resulting block, the signal will jump from zero to some other value or from some nonzero value to zero, which may create audible pops and clicks in the playback. To remove these pops and clicks, you can fade the ends of blocks.

This does not apply to MIDI blocks, as the cutting of MIDI blocks does not create pops and clicks.

To fade the ends of a block, click on that block to select it and then click on Block and then on Fade Ends in the Orinj menu. After you do so, during playback, Orinj will gradually increase the amplitude of the signal at the beginning of the block and gradually decrease the amplitude of the signal at the end of the block.

The gradual fading at the ends of blocks is short – e.g., 10 milliseconds – and will not be audible, but will be sufficient to eliminate pops and clicks.

Replace the audio data in blocks

Each block uses an audio file on your hard drive – wave file, MIDI file, or loop file. To see which audio file is used by a block, click the corresponding block to select it and then click on Block and then on File in the Orinj menu. You will see the following dialog.

Block file dialog

To change the audio file used by the block, click on the Replace button in the dialog. Then browse to the new file and open it.

Move blocks

If you want to move a wave, loop, or MIDI block, first click on the move pointer button (Move cursor button) in the pointer toolbar at the bottom of Orinj. Then click on the block and drag it to where you want the block to be. You can drag it both to the left or right in the same track or you can drag it to another track.

When you move the block, it will "snap" at certain places in your session. The snap places could be the beginning of measures in your progression (depending on how you set up the tempo and time signature of your session) or the beginning and end of other blocks. Snapping is there to ensure that the block that you are dragging aligns precisely with the snap places. If, for example, you want to align the block with the beginning of another block, you only need to drag it close enough to that place and release it when you see the vertical red snap line. Orinj will assume that you are attempting to align the two blocks and will place the moved block accordingly. If snapping was not available, you would have to zoom into your session and align the blocks manually. You may in fact have to zoom in very far as even small differences could be audible. If you do not want blocks to snap, you can change the Orinj snap options (see Orinj Preferences).

You can also move wave, loop, and MIDI blocks with the Position command in the Orinj menu. Select the block that you want to move by clicking on it. Then click on Block and then on Position. You will see the following dialog.

Block position dialog

This dialog shows the current position of the block in time in the format minutes:seconds:miliseconds. To move the block, enter a new start or end time and click OK. If you enter a new start time, the end time will adjust accordingly to reflect the length of the block. If you enter a new end time, the start time will adjust.

Remove and cut blocks

To remove a wave, loop, or MIDI block from your session, select it by clicking on it. You will see that the block is selected, as it will become lighter in color. Then click on Block and then on Remove in the Orinj menu.

To cut out a portion of a wave, loop, or MIDI block, select that portion and click on Block and then on Cut in the Orinj menu. When a portion is cut, the underlying wave, loop, or MIDI file residing on your hard drive does not change. Orinj will simply display a portion of that file in the multitrack session, but will not actually remove data from the file.

To select a portion of a block, first click on the select mouse pointer button (Select cursor button) in the pointer toolbar at the bottom of Orinj, and then drag the mouse over the block.

Note that the cursor will snap to the time signature line and to other blocks during selection, similarly to the snapping when moving blocks as described above.

To remove a wave, loop, or MIDI block both from your session and from your hard drive (to delete the corresponding file), select the block and click on Block and then on Destroy in the Orinj menu. The block that you "destroy" cannot be restored. This operation cannot be undone. The files that you may want to destroy are ones that you are sure will never be useful, such as a recording take, in which you made major mistakes.

Loop blocks

To loop a wave, loop, or MIDI file, click on the corresponding block to select it and then click on Block and then on Loop in the Orinj menu. You will see the following dialog.

Loop block dialog

Select the number of times the block should be looped and click OK. The block will be repeated so that each next block will start from the end of the previous one.

All looped blocks will use the same audio file on your hard drive. If you change the underlying file, such as when processing effects, all looped blocks will change at the same time. You can make individual blocks unique (pointing to a unique file) as described below.

Make blocks unique

When looping a wave, loop, or MIDI block as above, all resulting loop blocks will point to the same file on your hard drive. Similarly, if you insert a wave, loop, or MIDI file twice or more times into your session, there will be several blocks that point to the same file on your hard drive.

If you want to make one of the blocks independent of the others and pointing to a separate file, select the block and click on Block and then on Make Unique in the Orinj menu. A separate file will be created on your hard drive and the selected block will now point to this new file.

Examine the meta properties of blocks

Click on the block to select it. Then click on Block and then on Meta Properties in the Orinj menu. You will see a dialog that displays the meta properties of the block. Orinj handles the meta properties of different blocks – wave, loop, or MIDI – differently and what you see will depend on the type of block.

The following dialog is the one that will be shown for wave blocks.

Wave meta properties dialog

In the multitrack session, you cannot change the meta properties of blocks. You can only view them.

Display single waves, loops, and MIDI blocks

To open a wave in the Orinj single wave view, double-click on the wave block or click on it once to select it and then click on Block and then on View Single in the Orinj menu.

To open a MIDI file in the Orinj MIDI roll view, double-click on the MIDI block or click on it once to select it and then click on Block and then on View Single in the Orinj menu.

To open a loop file in the Orinj loop building view, double-click on the loop block or click on it once to select it and then click on Block and then on View Single in the Orinj menu.
