Sine, Triangle, Square, Saw
The Sine, Triangle, Square, and Saw menu items select the
corresponding type of source waveform. (Again, with a stereo file,
this waveform will feed into both the left and right sub-modules.)
Selecting any of these items will bring up some additional pop-up
menus and text fields. Use these controls to select the frequency
and initial phase of the waveform.
Note and Octave Pop-up Menus
Changing the Note or Octave pop-ups (for example, Note A, Octave
4) will automatically enter the corresponding frequency into the
Frequency field (440 Hz.).
Hz/Tempo/bpm Pop-up Menu
Use the Hz/Tempo/bpm pop-up menu to indicate whether you want
to specify a frequency in Hertz (cycles per second), as a multiple of
the host tempo, or in beats per minute (bpm).
To specify a low frequency oscillator in beats per minute, select
“bpm” and enter the tempo in beats per minute.
Use the “Initial Phase” field (labeled ° Phase) to specify the initial
phase of the sine/triangle/square/sawtooth waveform. For the sine
and triangle waves, 0° corresponds to an upward zero-crossing, 90°
corresponds to an instantaneous peak amplitude of +100%, 180° is
a downward zero-crossing, and 270° is the -100% peak.
Setting the initial phase to 0° can help avoid unnecessary initial
pops and clicks, since 0° is a zero-crossing.
For frequencies above 20 Hertz, the square and sawtooth
waveforms are smoothed to avoid aliasing.
