50 Parameters
Another parameter which affects the response of a room is its geometry; the more complex
the geometry of a room, the more reflexion are observed per unit of time. This quantity is known
as the time density and can be set trough the Diffusion knob. In a concert hall, the time density
is supposed to be quite high in order not to hear separate echoes which are characteristic of poor
sounding rooms.
The last parameter which affects our listening experience in a room, is the distance between
the sound source and the listener. While the room response is quite constant regardless of the
position of the source and the listener, the direct sound (the sound which comes directly from the
source) depends strongly on the position of the listener. The farther we are from the sound source
the quieter is the direct sound relatively to the room response. The ratio between the direct sound
and the room response is adjusted with the Mix knob which in other words is used to adjust the
perceived distance between the source and the listener. In its leftmost position, only the direct
sound is heard while when fully turned to the right, one only hears the room response. Note that
the Mix parameter is also adjustable from the Play view.
4.4 The Play View
The Play view is where the main performance oriented modules are located. Key parameters from
the Edit and FX view are also included for quick access. This view is loaded when starting the
instrument and can be accessed from another view by clicking on the Play button on the top part
of the interface.
The middle section of this view allows one to switch on and off the EQ, Compressor and
Reverb as well as the active effect modules. Key effect parameters are also adjustable as presented
in the description of the different effect modules in section 4.3
4.4.1 The Clock Module
This module is used to control the tempo of the different effects of the FX section
as well as that of the LFO and Arpeggiator modules when their respective sync button
is switched on. When Ultra Analog VA is launched in standalone mode the clock
tempo, in bpm, is set by using the Rate knob. The tempo can also be adjusted by
clicking at the desired tempo on the Tap Tempo pad of the module. Once the new
tempo is detected, the value of the Rate knob is automatically adjusted.
When using Ultra Analog VA in plugin mode, the Tap Tempo pad is replaced by
a Sync To Host switch. In its on position, the rate is synchronized with that of the host sequencer.
When switched off, the tempo is determined by the value of the Rate knob.
