Exp fades the audio out with an exponential curve. An exponential curve will fall quickly in
the beginning, and then flatten out as it reaches the end.
• PITCH SHIFT changes the pitch of the sample without changing its length. This is useful
when you want to change the pitch of the phrase sample in the sequence without changing
the tempo. The pitch can be set in a range from + / - 12 semitones. Keep in mind that the
audio quality will decrease with more extreme settings.
• TIME STRETCH can lengthen or shorten the sample without changing its pitch. This is
useful when you want to match one sample to another which has different tempo. You can
enter the original tempo of the sample and the desired tempo after processing. If you want
to change the sample length in percent, you can use the following method: For example, if
you wish to lengthen the sample by 20%, you set the original tempo to 100, then set the
new tempo to 80. This way you will obtain a sample that is 20% longer.
• GAIN CHANGE allows the volume of a sample to be raised or lowered by up to 18dB. Note
that this function is different than Normalize because it will allow volumes beyond clipping
level. This may be a desired effect, but please make sure to watch your output level.
• COPY makes a copy of the selected sample and adds a consecutive number after the
sample name.
• BIT REDUCE diminishes the bit resolution of a sample, effectively lowering its degree of
faithful reproduction. A common application is achieving a dirty "old school" sizzle on drum
loops, but with a digital "edge." The sound is similar to the Resampler effect, but it will
permanently alter the sample. You can reduce the bit rate down to 1 bit.
• STEREO > MONO converts a stereo sample to a new mono sample. The following options
are available: Left will only use the left channel for conversion; Right will only use the right
channel for conversion; Sum will combine the left and right audio channels to a single
mono channel. You can also enter a name for the new mono sample. The new sample will
be added to the current Project.
The PROJECT INFORMATION
The Project Information section shows all available Programs and
all available samples in the current Project.
Double-click on a sample in the Sample column to load it into the
Sample Edit window.
Right-click on a Program to open a context menu with the following
options:
• Duplicate makes a copy of the selected Program and adds
a "-1" to the Program name.
• Delete deletes the selected Program. To avoid accidental
deletion, a query window opens for confirmation.
• Save saves the current Program to your hard disk. A dialog window opens automatically
where you can choose a data path for saving. You can also name your Program file.
• Rename opens a window where you can rename your Program.
Right-click on a Sample to open a context menu with the following options:
• Delete deletes the selected sample. To avoid accidental deletion, a query window opens
for confirmation.
