Kyra Manual
Sample Rate
The frequency of the intervals used to represent sound in a
digital audio system. Higher sample rates allow the re-
presentation of higher frequency sounds as well as allo-
wing the system to be more tolerant of out of band signals
that can cause aliasing. Kyra has a native sample rate of
32x (1536kHz) for all sound generation and 2x (96kHz) for
filtering, effects and final audio output. The result of this is
sounds that are virtually alias-free.
Sawtooth
A harmonically-rich waveform that has a trumpet-like
sound. An ideal source for subtractive synthesis owing to
its rich harmonic content which includes odd and even
harmonics. Available as a basic VA waveform in both Oscil-
lator Groups and their Sub Oscillators. Technically, Kyra
produces a ramp waveform but the harmonic content is
identical.
Screen Saver
A timer that reduces the contrast and eventually switches
off the display in order to reduce the risk of image burn or
shortened display lifetime. By leaving the screen saver on
its default settings, there's less chance of damage to the
OLED display if you forget to switch off your instrument as
the screensaver will protect it. The instrument remains
fully functional even if the display has switched off. Mani-
pulating any front panel control will restore the display.
Disabling the screensaver is not recommended as leaving
it on for very long periods may shorten its lifetime. Note
that the screensaver will activate after 24 hours even if it is
disabled.
Semitone
A musical interval representing 100 cents or one twelfth of
an octave. The interval between two keys on a keyboard.
Sequencer
A computer program (or occasionally a standalone hard-
ware device) that allows the recording, arrangement and
replay of MIDI data. A sequencer with the ability to record
and process digital audio is usually referred to as a DAW
(Digital Audio Workstation).
Signal to noise ratio
The 'distance' between the signal (the bit you want to hear,
the music) and the 'noise' (the bit you don't want to hear).
As the noise level in many systems is largely fixed, higher
(and hence better) signal to noise ratios are obtained by
having the signal as loud ('hot') as possible. That is true on
Kyra and you should ensure levels are as high as they can
be without risking distortion. Excessively low signal levels
