Orinj version 3.0.0
In the Orinj multitrack session, a wave will appear as a block inside a track, such as the one in the picture below.
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 MIDI file will appear as a similar block, but, instead of displaying the wave peaks and troughs, it will show the MIDI notes.
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.
Insert wave files and MIDI files
To insert an existing wave file or MIDI 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 waves and MIDI files
To mute a wave block or a MIDI block, click on the block to select it and then click on Wave and then on Mute in the Orinj menu. If you want to mute the whole track, see Orinj Working with session tracks.
Rename wave files and MIDI files
To rename a file, click the corresponding block to select it and then click on Wave and then on Wave File in the Orinj menu. You will see the following dialog.
If you change the file name and click OK, you will be prompted to choose whether to rename the existing file or create a copy of the original file (and thus preserve the original file with its original name).
Move wave files and MIDI files
If you want to move a wave or MIDI block, first click on the move pointer button () in the pointer toolbar at the bottom of Orinj. Then click on the wave or MIDI 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 wave or MIDI 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 wave or MIDI blocks. Snapping is there to ensure that the wave block that you are dragging aligns precisely with the snap places. If, for example, you want to align the wave with the beginning of another wave, 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 wave accordingly. If Orinj did not snap, 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 the wave to snap, you have to change your snap options (see Orinj Preferences).
You can also move wave and MIDI blocks with the Block Position command in the Orinj menu. Select the block that you want to move by clicking on it. Then click on Wave and then Block Position. You will see the following dialog.
This dialog shows the current position of the wave or MIDI block in terms of time in the format minutes:seconds:miliseconds. To move the wave of MIDI 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 waves and MIDI files
To remove a wave 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 Session and then on Cut in the Orinj menu.
To cut out a portion of a wave or a MIDI block, select that portion and click on Session and then on Cut in the Orinj menu. When a portion of the wave or MIDI block is cut, the underlying wave 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 wave, first click on the select mouse pointer button () in the pointer toolbar at the bottom of Orinj, and then drag the mouse over the wave.
Note that the cursor will snap to the time signature line and to other waves during selection, similarly to the snapping when moving waves described above.
To remove a wave or a MIDI block both from your session and from your hard drive (to delete the corresponding file), select the block and click on Session and then on Destroy in the Orinj menu. The wave that you "destroy" cannot be restored. This operation cannot be undone. This means, in general, that waves and MIDI files that you may want to destroy are ones that you are sure will never be useful. A recording take, in which you made major mistakes, could be an example.
Loop waves and MIDI files
To loop a wave or a MIDI file, click on the corresponding block to select it and then click on Wave and then on Loop in the Orinj menu. You will see the following dialog.
Select the number of times the wave or MIDI 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 wave or MIDI blocks will use the same wave or MIDI file on your hard drive. If, for example, you modify a wave, such as when processing effects, all blocks for the looped wave will change at the same time. You can make individual blocks unique (pointing to a unique file) as described below.
Create unique waves and MIDI files
When looping a wave or a MIDI block as above, all resulting loop blocks will point to the same file on your hard drive. Similarly, if you insert a wave file or a MIDI file twice or more times into your session, there will be several wave or MIDI 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 wave or MIDI file, select the block and click on Wave 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.
Convert waves from mono to stereo and vice versa
To change the number of channels that are used by a wave file, click on the corresponding wave block to select it and click on Wave and then on Audio Format in the Orinj menu. You will see the following dialog.
Choose whether the wave should have one or two channels and click OK. If you change the number of channels for the wave, Orinj will create a new copy of the wave file and will preserve the original wave file.
If you convert a mono wave to a stereo wave (from one to two channels), both channels in the new wave will contain the same information. If you convert a stereo wave to a mono wave, the mono wave will be the mix of the left and right channel of the original stereo wave.
The wave audio format dialog only displays the wave sampling rate and sampling resolution, but does not allow you to change those. The sampling rate and sampling resolution of waves can be changed in the single wave view of Orinj.
Examine the frequency content of waves
To examine the frequency content of a wave, click on the corresponding wave block to select it. Then click on Wave and then on Frequency Content in the Orinj menu. You will see the following dialog.
This dialog is only informational and does not allow you to change the properties of the wave. It shows you which frequencies are prominent in the wave file.
The frequency content will be computed for specific time and frequency intervals, which you can change. You can also choose the channels for which the frequency content is computed as well as the frequency precision. Once you make changes to any of these parameters, click on the Update button to update the dialog graph. If for example you want to see the frequency content of the wave between 2.5 sec and 3 sec from the beginning of the wave, and for every 2Hz frequency between 0 Hz and 1000 Hz, you can enter 00:02.500 as the start time, 00:03:000 as the end time, 2 as the precision, 0 as the start frequency, and 1000 as the end frequency.
The precision used to detect frequencies is important. If, for example, it is set at 20 Hz, Orinj will examine the wave for the frequencies 20Hz, 40 Hz, 60 Hz, and so on, but will not check for frequencies in between. Thus, it may miss some frequencies, the magnitude of which may be significant. It is usually better to use smaller precision numbers (e.g., to check every 1 Hz). The only disadvantage of better precision is that the computations will be slower.
Change the meta properties of waves
First, click on the wave block to select it. Then click on Wave and then on Properties in the Orinj menu. You will get the dialog in the picture below.
Use this dialog to add meta data and to change the meta data of your waves. The comments that you enter here will be placed in the wave file in a standard format so that they can be recognized by other software applications besides Orinj.
There are accepted ways of formatting the information in certain fields. Note for example the way the creation date and copyright statement are entered. Keywords should be separated by semicolons. Move the mouse over the field to see explanations of what the fields mean and, if applicable, to get hints on entering the appropriate information.
The meta properties of a wave are encoded in the wave file. This means that, if you click OK in the dialog above, the original wave file will be overwritten by a new one. The new one will contain the same sound data, but the new meta properties that you specified.
Display single waves and MIDI files
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 Wave and then on View Single Wave 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 Wave and then on View Single Wave in the Orinj menu.
Pitch shift waves
To pitch shift a wave without changing its tempo or length, click on the wave block to select it and then click on Wave and then on Pitch Shift in the Orinj menu. You will see the following dialog.
Use the pitch drop-down box to select the amount of the pitch in half steps up or down. For more precise pitch shifting use the slider and the pitch percent field to adjust the pitch. Both of these controls work together and changing one will change the other one. Use the FFT drop down box to change the precision of the pitch shift computations. This combo box displays the size of the discrete Fourier transform employed by the pitch shifting. A larger transform will result in more frequencies detected, but over larger intervals of the wave. Click OK in the dialog once you selected the proper pitch shift. The wave that you selected will then be converted to reflect this pitch adjustment. The original wave will not be changed. Orinj will create a new wave file.
To stretch a wave without changing its pitch, click on the corresponding wave block to select it and then click on Wave and then on Stretch in the Orinj menu. You will see the following dialog.
Use the slider or type a stretch percent to specify the stretch or shrink ratio. Use the FFT drop-down box to specify the precision of the operation. As with pitch shifting, this is the size of the discrete Fourier transform employed by the stretching computations and a larger transform will result in more frequencies detected, but over larger intervals of the sound data. Click OK in the dialog when you are done. Orinj will create a new wave file, which would be the shrunk or stretched version of the original file. The original file will not be changed.
Stretching and shrinking in the current version of Orinj does not work for selected portions of the wave. Orinj will always stretch or shrink the whole wave.
To reverse a wave, click on the wave to select it and then click on Wave and then on Reverse in the Orinj menu. Orinj will create a new wave that sounds just like the original one played backwards. The original wave file will be preserved. A new wave file will be created.
Split stereo waves
Click on a stereo wave to select it and then click on Wave and then on Split Stereo Wave to create two mono waves from the stereo wave. The first mono wave one will contain the left channel sound data from the original wave and will be inserted instead of the original wave. The second one will contain the right channel sound data from the original wave and will be inserted at the same time as the original one but one track down. The original file will be preserved, but will be removed from the session.
