Troubleshooting
Low Levels or Noise
As Kyra has such a large dynamic range, single Part playing
will result in relatively low levels. These lower levels are
necessary to ensure Kyra can output up to 128 notes over
8 Parts without using excessive compression. When
playing single Part sounds, you might need to boost the
input gain on your mixer or amplifier, this is normal. Check
that the
Master Volume
control is at its maximum setting;
this will ensure noise is minimised. Kyra has very high-
quality components in its line outputs and significant noise
(hiss) should not be evident if everything is set up cor-
rectly. If you find the need to turn the
Master Volume
control much below 100, consider turning down the trim
on your mixer or the volume of your amplifier and turning
up the
Master Volume
control to get similar levels.
For USB recordings, as the audio bit depth is 24 bits,
boosting the level recorded is unlikely to result in signifi-
cant degradation of the sound quality when normalising
the recorded audio.
Hum
A background hum indicates the likely presence of a
ground loop in your overall system. Use headphones
connected directly to Kyra to confirm the hum is not
present at that output. Solving ground loops is very much
dependent on the set up of your studio and is beyond the
scope of this manual although removing connections in
your setup (not just on Kyra) one at a time in your system
is a good way to find out what is causing the hum. DIN
MIDI can't form a ground loop but USB can, as can the line
outputs if you have them connected to more than one
piece of equipment (e.g. two amplifiers or mixers).
Interference
The presence of digital static, interference or crackling on
the line outputs is likely to be caused by faulty connec-
tions. Check that jack plugs are fully inserted and are in
good condition. Try replacement leads and ensure they are
balanced TRS types - balanced connections considerably
increase tolerance of interference. Ensure Kyra is connec-
ted to balanced line inputs. Don't use microphone, phono
or guitar inputs on your amplifier, mixer or soundcard.
Some mixers and soundcards have switchable inputs -
ensure the switch is in the balanced line level input setting.
Check nothing near Kyra or the leads to your mixer is
