18 HX3.5 Mainboard
Gating Mode: The HX3.5 default setting (B3 mode B3/9 Drb) implies mechanical key
contacts, 2 2/3’ or 4’ percussion, and 9 drawbars per manual. This menu item and the
following options require the extended license.
o H100/12 Drb switches to the H100 organ model including 3 additional mixtures. This
activates the respective drawbars. B3 percussion is de-activated in this mode, instead the
H-Perc 16‘ … H-Perc Mixt3 in submenu Voice Upper settings are effective if Perc ON is
selected. By means of this mask you may assign percussion individually to each available
harmonic. Percussion always sounds without vibrato and phasing rotor. This mode may be
combined with all generator models.
o EnvelopeGen (EG) substitutes “mechanical” keying, which generates a key click, by “soft”
electronic keying. This is the way to model the entirely electronic organs of the 80s. In this
mode three additional mixtures are available; the respective drawbars are active. An ADSR
envelope is applied to the harmonics selected by means of the EnvEna 16‘ … EnvEna
Mixt3 settings on the Panel or with TouchOSC.
o EG +PercDrb works like EnvelopeGen (EG), but instead of the ADSR envelope a
percussion envelope is active on the harmonics selected by the EnvEna 16‘ … EnvEna
Mixt3 settings in submenu Voice Upper. The percussion effect amount can be adjusted with
the Envelope Generator Drawbars (EGenvDB 16‘ …Mixt3) on the Panel or with TouchOSC.
o EG +TimeDrb as well works like EnvelopeGen (EG), but in this mode the Envelope
Generator Drawbars (EGenvDB 16‘ …Mixt3) affect the decay and release times of the
ADSR envelope on harmonics selected by the EnvEna 16‘ … EnvEna Mixt3 settings in
submenu Voice Upper. Thus you can create interesting transient and decay effects similar
to a Fourier synthesizer by using time settings depending on the respective harmonics.
TG WaveSet: Determines the content of harmonics in the generated sound. Automatically set
for the selected generator, but can be overridden in this menu:
o B3 25%...38% k2 – B3, clean to rich harmonics (new to old organ)
o Sine 2% k2 – clean LSI/transistor sine generator
o Sawt Fltrd – Sawtooth-like tone
o Sine LC Gen – sine wave generator with moderate k2 content
o Sine TOSGen – square wave generator with sine wave filtering, sounds slighty hollow
TG Flutter: Adjusts tone generator "sloppyness" (spring clutch tension, bearing precision, and
resulting slow phase shifts and pitch changes).
TG Leakage: Sets tone generator leakage (crosstalk noise of adjacent notes, “growl”).
