Kyra Manual
Octave
A musical interval corresponding to a doubling or halving
of pitch.
OLED
Organic Light Emitting Diode. A relatively new display
technology that offers many improvements over traditio-
nal LCDs (Liquid Crystal Displays). Typical advantages
include faster response times as well as dramatically im-
proved contrast and viewing angles. Kyra features an
OLED display.
Oscillator Group
A grouping of oscillators within the sound source section
of Kyra. Kyra supports two independent Oscillator Groups
providing a total of ten sound sources per voice.
Outboard
Signal processing units in the Kyra signal chain that are
applied externally, i.e. beyond its own internal effects
units.
Oversampling
The technique of operating a digital audio system at a
multiple of the fundamental sample rate (of 48kHz in the
case of Kyra) to avoid aliasing. Kyra's oscillators operate at
32x the fundamental rate and use other techniques as well
to all but eliminate aliasing. The filters and effects units are
two times oversampled. The result is a system with a clean,
bright top end that can support techniques particularly
prone to aliasing such as hard sync, FM, ring modulation
and wavetable playback. Systems that are not oversampled
often suffer from aliasing and/or have muddy or noisy top
end performance where they must use intrusive filtering
to attempt to avoid aliasing or attempt to conceal it when it
has already happened. When configured for 48kHz output
there is a small possibility of aliasing on the USB audio
streams.
Pan
The location of a sound in the stereo field. 'Panning' im-
plies changing the pan value so that the sound 'moves'
within the stereo field.
Part
The configuration of one of the 8 independent sub-
modules of Kyra. It is reasonable to view a Part as a com-
plete synthesizer. Each Part can play a configurable sound
(as determined by the Patch loaded into it) and has its own
set of configurable parameters.
Passband
The range of filters passed (not attenuated) by a filter.
