Kyra Manual
de extra bass and body to a sound. Kyra features an inde-
pendently tunable Sub Oscillator in each of its two Oscilla-
tor Groups. The hypersaw also has a sub oscillator feature.
Sustain
The third of the four segments in an ADSR-style envelope
generator. The sustain segment starts when the decay
reaches the configured sustain level and ends when the
key is released. The sustain pedal effectively holds the
sustain period of a note until the sustain pedal is released,
regardless of when the keys themselves are released.
Sustain Pedal
Sometimes shortened to sus or hold pedal. A pedal (and
corresponding MIDI command) to sustain notes regardless
of the lifting of fingers from keys until the sustain pedal is
released.
System Exclusive
Often shortened to 'SysEx'. A part of the MIDI specification
that allows proprietary (non-standard) information to be
exchanged between MIDI devices. Kyra uses System Exclu-
sive messages to allow the saving, configuration and resto-
ring of Patch, Multi and System configuration data. Kyra
also supports certain universal SysEx messages, these are
detailed in the MIDI implementation chart.
Timbre
The tonal quality of a sound.
Tremolo
Amplitude (level) modulation by a periodic source, typical-
ly an LFO
TRS
Tip, ring, sleeve. A type of audio cable that carries a single
channel of balanced audio. On Kyra, two cables are requi-
red for stereo operation. Kyra's line outputs are balanced
TRS-type jacks. Kyra will operate with non-balanced cables
and mixers but you will lose the benefits of balanced audio
(primarily, increased tolerance of interference and noise).
This loss of quality will be more evident with longer
cables.
UAC2
USB Audio Class 2.0. A specification for USB that supports
multichannel, low latency, high quality audio over USB.
macOS supports UAC2 natively but Windows, as at
Windows 10, requires a driver to be installed to handle
UAC2.
