Caution: If the Single Cycle value shown
is not an integer number, adjust the Sample
Rate until it is an integer. Then use the
Sample Rate Convert function (Digital Tools
II, submodule SampleRate Convert (0) to
convert the sample to the new rate.
This submodule contains several additional numbered functions. These
are extremely useful utilities for manipulating samples. The following is
a short description of each function.
0. Sample Calculator: Calculates and displays the optimum pitch to
sample rate ratios for single cycle loops at the desired pitch.
1. Taper: Adds a fade-in and or fade-out to the sample, thus
smoothing out samples with abrupt beginnings or endings.
2. Gain Change: Alters the level of all or a part of a sample.
3. Reverse: Reverses all or part of a sample.
4. Stereo <-> Mono: Converts a stereo sample to mono or a mono
sample to stereo.
5. Left <-> Right: Swaps sides if the current sample is stereo or moves
a mono sample to the other side.
6. DC Filter: Removes the DC component from a sample, centering
the waveform around the zero axis.
7. Sample Integrity: Samples may occasionally have slight looping
problems due to data corruption of the sample header file. This
function remedies the problem by reconstructing the sample header.

0. Sample Calculator

Use the Sample Calculator to compute the sample rate for a perfect
single cycle loop. You provide the pitch and sample rate, the Single
Cycle field displays the single cycle value based on the information you
provide. Use the Single Cycle value to adjust the loop length. This
provides an "in tune" single cycle loop.
1. Activate Digital Processing module.
2. Select Digital Tools I (7), Sample Calculator (0). The display will
reveal the Sample Calculator.
SAMPLE CALCULATOR
Pitch:
Sample Rate: 44001Hz
Single Cycle: 100.00
3. Enter the pitch of the sample using either the keyboard or Data
Entry Control. The number of samples in a single cycle changes for
each note.
4. Select sample rate on line three. Use the INC/DEC buttons to
change the value. The number of samples in a single cycle changes
for each sample rate.
To adjust the loop refer to the Digital Processing, submodule Loop (2).
