Harmonics On/Off
D Click the On/Off LED buttons to activate/deactivate the Harmonics section.
Harmonics selector
D Click the Harmonics name box to bring up a menu of the available harmonic algorithms.
The available Harmonics types are:
•Random Gain
This alters the gain for each of the partials in the signal in a random fashion. Turn the Pos knob to change the
randomization “pattern” and the Amount knob to change the partial gain levels in the “pattern”.
• Harmonic 1-8 Mix
This alters the gain/attenuation for the first eight partials in the signal. Turn the Pos knob to crossfade between
the partials and the Amount knob to change the partial gain/attenuation level. Amount levels below 50% attenu-
ate all partials but the one selected with the Pos knob. Amount levels above 50% attenuate the partial selected
with the Pos knob.
• Odd-Even
This alters the gain/attenuation of the partials in the signal. At Pos=0% the Amount knob controls the mix strictly
between the odd and even partials in the signal. At other Pos values, the gain/attenuation is not strictly on odd and
even partials. At Amount=50% the Pos value has no effect.
•Stretch
This stretches or squeezes all partials (overtones) - except for the fundamental - in the signal, up or down in the
frequency range. Perfect for turning a harmonic signal into a more inharmonic one. Change the stretch amount
with the Amount knob. The Pos knob controls the start phase of all the overtones. At Pos=0% all partials start at
the same phase. When Amount is set fairly high the Pos parameter have little or no influence on the sound.
q Try this with the Karplus-Strong waveform to create really realistic metallic sounds, see “Karplus-Strong”!
•Ensemble
This is the perfect algorithm for really dense pad sounds. The Ensemble algorithm simulates a type of chorus
effect by utilizing noise modulation of the partials. Set the noise frequency with the Pos knob and the mix level with
the Amount knob.
• Ensemble Sparse
The Ensemble Sparse algorithm also utilizes noise modulation of the partials, but here a lot of noise frequency
bands are cut out. This makes Ensemble Sparse sound more animated and less smooth than the Ensemble algo-
rithm described above. Set the noise frequency with the Pos knob and the mix level with the Amount knob.
•HF Noise
This amplitude modulates the high frequencies in the signal with (high-frequency) noise, perfect for adding “breath
noise” to the signal, for example. Set the noise frequency with the Pos knob and the noise mix level with the
Amount knob.
•Harmonic Lag A-R
The Harmonic Lag A-R algorithm is designed especially for use with the User Wave algorithm in the Spectral Filter
(see “User Wave”) to create vocoder effects. The Harmonic Lag A-R algorithm controls the Spectral Filter - so the
Spectral Filter has to be on for this to work!
Note that the Harmonic Lag A-R algorithm works on the filter partials - not the oscillator’s signal partials. Set the
Attack time of the filter partials with the Pos knob and the Release time with the Amount knob. These controls
work similarly to the Attack and Decay parameters on the BV512 Vocoder device.

D Turn the Pos knob to change the frequency of the currently selected Harmonics algorithm.
The frequency spectrum is updated in real-time and shown in the Spectral Filter display.
