Sample Loop/Stop Tab - Clavia Nord Wave User Manual

Sample Loop/Stop Tab

In this tab are the functions that will assist you in finding a
loop for the sample that is currently in focus, as indicated
by the yellow color in the Keyboard Grid. as soon as an
audio file or a selection from an audio file is assigned as a
sample, loop markers will automatically be created by the
Nord Wave Manager.
Looping a sample is very useful in order to be able to play
the sample for a time period that is longer than the actual
sample itself. It also helps conserving the available memory
space, you can have more samples available.
a loop in a sample consists of two positional markers in the
audio, the loop start and the loop end markers. Visualize
the playback of a sample as a horizontal journey from the
start of the waveform at the extreme left, towards the end
at the right.
Somewhere along the line you will pass the loop start
marker, making a mental note of its location. You continue
to travel towards the end of the audio file but when you
reach the loop end marker, you immediately go back to the
loop start marker and resume the path towards the end.
and then you hit the loop end marker again, go back to the
loop start, and so on.
Creating a perfect, seamless loop can sometimes be a
bit difficult. Sometimes the audio at the loop start is very
different compared to the audio at the loop end marker,
which will produce audible and perhaps unwanted arti-
facts in the sound.
In order to minimize certain loop artifacts, a crossfade
function can be used. this uses audio that is before the
loop start marker, and mixes this with audio that is before
the loop end marker when the loop is playing back.
a crossfade has usually several parameters to set the
length of the crossfade, and to adjust the taper of how
these two sound bites will blend into each other during
playback. this can help to smooth things out and create a
better sounding loop.

Any audio data after the loop end point will be auto-
matically discarded by the Nord Wave Manager when
you create the Sample Instrument from the Project.
Waveform graph colors
the waveform graph presents the loop by showing certain
areas in different colors. the position of the loop start
marker is at the left edge of the blue area. the position of
the loop end marker is at the right end of the darker blue
area.
Loop Start Loop End
XFade beg. section XFade end section
a crossfades first section is indicated with the light blue
area that is before the loop start, to the left of the blue
area. the crossfades end section is the darkest area im-
mediately to the left of the loop end marker. as these set-
tings are changed by you, the indication in the graph will
change as well.
You can set the position of the loop start marker by clicking
anywhere in the graph. If you right-click to the right of the
loop start marker, you can set a new loop end marker – and
change the actual loop length.
