The Nash - Virtual Organ
To the left of the lower manual are the drawbars. These produce the same ‘footages’ as standard Hammond drawbars, but emit slightly more complex waveforms than the simple sines of the Hammond. The drawbars have to be selected before they become active. Select and make the drawbars active using the yellow U/L/D (Upper/Lower/Drawbars) toggle on the panel just above them. With this toggle set to the D position, the drawbar set becomes active. Draw down a given drawbar with the mouse to increase its volume.
To the left of the upper manual is a control panel. Along the top of this panel are the ‘orchestral voice’ faders for both manuals – divided in the middle by the Vibrato controls.
To the left of the Vibrato controls are the three ‘orchestral voice’ faders for the Lower manual. These will only be active if the Lower manual is selected, by setting the U/L/D toggle in the L position. Vary the positions of the ‘orchestral voice’ faders to increase of decrease their respective volumes.
To the right of the Vibrato controls are the six ‘orchestral voice’ faders for the Upper manual. These will only be active if the Upper manual is selected, by setting the U/L/D toggle in the U position. Vary the positions of the ‘orchestral voice’ faders to increase of decrease their respective volumes.
The tonality of the ‘orchestral voice’ faders is modelled on their analogue equivalents from the home organs of three decades ago, and thus is not intended to represent the real orchestral instruments their labels suggest.
The Vibrato controls incorporate faders for Vibrato and Speed. Vibrato increases or decreases the depth of vibrato. Speed increases or decreases the speed. Vibrato affects all sound from the instrument, regardless of which manual is set, or whether the drawbars or preset tabs are in use.
Below the ‘orchestral voice’ faders are the preset tabs. These provide ‘standalone’ sounds which will override any other tones set on the organ. They must be disengaged manually. That is, they must be switched out (clicked again with the mouse) before another preset tab is selected, or the new tab may not sound.
To the right of the upper manual, the master Volume control is located above the Power switch.
To the right of the lower manual is a control panel for effects. On the top line are the Echo controls. The white Echo tab simply engages or disengages the effect. The Rate fader increases or decreases the time between echo repeats. The Repeat fader determines the number of echo repeats. The Mix fader sets the volume of the echo repeats.
The YNM button works only on the upper manual. YNM simulates a ‘waggling’ back and forth of the ‘orchestral voice’ faders – which is something I sometimes used to do manually when using an old Yamaha home organ with a band I was in. It gives a sort of wah/animation effect by cyclically increasing and decreasing the volume of the voices. The precise effect will depend on how you set the upper manual’s ‘orchestral voice’ faders. The YNM Rate knob increases or decreases the cycle speed of the effect.
The green display above the upper manual offers a few example presets. Click on the display and then select a preset from the drop-down list.
