The Sine Sweep section generates a user-defined frequency spectrum sine wave sweep.
The Time field determines the duration of the sweep. The Start and End Freq(uency)
parameters define the oscillator frequency at the beginning and end of the sine sweep.
The Trigger button behavior can be switched via the edit field below:
• single: pressing the x1 symbol triggers the sweep once.
• continuous: pressing the Infinity symbol triggers the sweep indefinitely.
Tuner
The ET1 Tuner plug-in can be used to tune acoustic instruments. This ensures that
software instruments, existing samples or recordings are perfectly tuned to any new
acoustic recordings you may make.
You would normally insert the ET1 Tuner into an Input fader channel.
Use couldn’t be simpler. There is a single tuning control at the bottom of the ET1 Tuner
interface. To adjust, simply click and drag it to the desired pitch for A. By default, the
ET1 Tuner is set to concert pitch A = 440 Hz.
The Keynote and Octave panels display the incoming note pitch, and the octave that
the incoming note belongs to. This matches the MIDI octave range, with the C above
middle C displayed as C4, and middle C displayed as C3.
The numeric semicircle around the top of the ET1 interface displays the amount of
variance—in cents—from the original pitch. The range is displayed in single semitone
steps ±6 cents, and then in larger increments to a maximum of ±50 cents.
If the incoming note is slightly flat, the indicator segments to the left will be
illuminated. If the incoming note is slightly sharp, the indicator segments to the right
will be illuminated.
When the pitch is perfect, the center segment is lit.
