Edit Parameters
15 Exciter
The Exciter effect adds harmonics as an enhancement to the dry signal. A popular use is to add a
high-end “sheen” to vocals, acoustic guitars, etc.
Parameter 1 (Drive)
– The amount of gain into the exciter, 0-99%. Higher gains produce more
harmonics.
Parameter 2 (Frequency)
– This controls the frequency of a low-cut filter preceding the exciter,
allowing it to generate harmonics based on the higher frequencies.
16 Karaoke
This is a vocal removal effect that cancels any audio (above the crossover point) that is mixed down
the center of the stereo field. Lead vocals are usually mixed this way, whereas instruments (and
some background vocals) are usually panned away from center or stereo-mixed in other ways.
Vocals mixed to center often have stereo effects added to them, so you will hear only the effects in
many cases.
Note:
Due to the nature of this effect, it will only work correctly under the following
circumstances:
• Engine A in series mode (typical usage), or Engine B if Engine A is off
• Engine A or B in parallel mode with the other engine off (muted)
Parameter 1 (Crossover)
– Frequencies lower than this point will not be canceled. Bass and kick
drum are popular choices for mixing down the center, and the goal is for that low end to still be
audible. Increase it for more bass, decrease for more cancellation on low-pitched vocals. Range is
100 Hz –190 Hz (display shows 0.0. – 9.0.).
Parameter 2 (Pan)
– This will control the balance between the left/right mix (treble side, after the
crossover). This could be used to get less cancellation when wanted, or get more cancellation in
cases where the vocal may be slightly panned (or the source left and right signals are not the same
exact level). Range is +/- 9 (default is 0).
Tip:
What happens if you drive a mono signal into this effect? Interestingly enough, it acts as
a drastic midrange scoop. Raising the Crossover point will increase the bass, and moving the
Cancel Amt away from zero will increase the midrange. There is usually a substantial volume
loss, but the output level can add 6 dB, and the other effect block can add more if used in
series. Factory presets 71 and 81 use the Karaoke effect as a mid scoop for guitar.
