Using the pencil tool, draw a new shape.
This technique is almost exclusively used for repair of audio
anomalies —
the idea is to correct a problem by drawing a smoother, less jagged waveform than the
original. In our example, the click is drawn nearly flat to get rid of the sound almost entirely.
And so the click has been removed.
NOTE:
This repair technique depends on the very nature of waveform drawing. The taller the
waveform, the louder the sound it represents, thus the shorter the waveform (the nearer to the middle
line —
which is zero) the quieter the sound. With the click example, the idea is to draw the new shape
nearly flat and on the middle line, so that it has almost no amplitude or loudness at all. If the click
exists in the middle of a smooth curve, try redrawing the curve so that the click is smoothed out.
ADDITIONAL NOTES:
The pencil tool cannot be used when the SX-1 is externally synchronized
. This is due to the fact that
mouse edit operations can cause the transport to locate in some situations. Instead of getting the
machine into a mode where a possible problem could ensue (due to locate commands from the external
m a s t e r a n d t h e p e n c i l t o o l f i g h t i n g e a c h o t h e r ) , t h i s o p e r a t i o n w a s d i s a l l o w e d .
It is not possible to perform pencil edits at the extreme edges of a file, during the fade in/fade out area
.
Data cannot be created from silence
. This means that the pencil tool can only modify existing data —
it
cannot create data where none previously existed.

New Level edit operation for simple gain changes
The original Gain/Fade edit op has a beginning value and an end value —
designed for quickly creating
linear fade ins and fade outs. The side effect of having separate beginning and ending values was that it
took a moment or two to get both values the same, if all you wanted to do was raise or lower the level
for the entire event.
Hence, a new edit op named Level was added to give you a simple way to change the volume in
events. It has one parameter —
Gain —
which it will apply to the region selected with the mouse.
