1. Recording Samples (Sampling)
For monaural samples N = 5.5, and for stereo samples N = 8.
Also, the number of slices is doubled for stereo samples.
With the memory expanded to the maximum 64 megabytes, for
example, if the entire memory is empty and a 44.1 kHz sample is
sliced to 32 slices, the longest possible sampling time will be
approximately:
BEAT1~3, PHRASE1~4: approx. 138 seconds (mono), 47 sec-
onds (stereo). QUICK: approx. 253 seconds (mono), 126 seconds
(stereo).
