• Waveform buttons: Set the waveform type used by the LFO. You can choose between
triangle, falling and rising sawtooth, square up and down around zero (bipolar, good
for trills), square up from zero (unipolar, good for changing between two definable
pitches), a random stepped waveform (S&H), and a smoothed random waveform for
each LFO.
• LFO Rate knob and field: Determines the speed of modulation. Values to the left of the
center positions are synchronized with the host application tempo and include bar
values, triplet values, and more. Values to the right of the center positions are non
synchronized and are displayed in Hertz (cycles per second).
Note: The ability to use synchronous bar values could be used to perform a formant
shift every four bars on a cycled one-bar percussion part, for example. Alternatively,
you could perform the same formant shift on every eighth-note triplet within the same
part. Either method can generate interesting results and can lead to new ideas, or add
new life to old audio material.
EVOC 20 TrackOscillator Output Parameters
The Output section provides control over the type, stereo width, and level of signal that
is sent from the EVOC 20 TrackOscillator.
• Signal menu: Determines the signal that is sent to the EVOC 20 TrackOscillator main
outputs. You can choose among the following settings:
• Voc(oder): Choose to hear the vocoder effect.
• Syn(thesis): Choose to hear only the synthesizer signal.
• Ana(lysis): Choose to hear only the analysis signal.
Note: The last two settings are mainly useful for monitoring purposes.
• Level slider: Controls the volume of the EVOC 20 TrackOscillator output signal.
