Sampling and Sample Editing
Setting Up For Sampling
15-4
KHz consists of 96,000 individual samples (48,000 x 2), taking up 192,000 bytes (about 188K) of
sample memory. The same sample taken at 32 KHz takes up about 125K. A one-second mono
sample taken at 32 KHz takes up about 63K.
If you plan to do a lot of sampling, you may want to consider adding sample memory to your
K2vx. SIMMS (Single In-line Memory Modules) are available at your dealer, or at most
computer stores or mail-order houses. Be sure to read "Choosing SIMMs for Sample RAM" in
Chapter 8 of the
K2vx Reference Guide
before you go SIMM shopping, though.
At a sampling rate of 44.1 KHz, each megabyte you add increases your sample time by about 12
seconds. The chart below lists a few standard sample RAM conÞgurations and their total
sample time capacity (in seconds) at various sample rates.
Mode
Use the Mode parameter to select mono or stereo sampling. (Keep in mind that stereo samples
take up twice as much memory as mono samples.) Use a value of Mono(L) for a mono signal.
You can use either Mono(L) or Mono(R) to isolate either the left or right side of a stereo signal.
Audio Sampling Input doubles as a two channel "drum" trigger, allowing audio signals to
trigger samples. On the Sample page, set Mode to Trigger. Adjust Thresh to control triggering
sensitivity. This triggers the currently assigned click program. The left input will trigger click
key note 1, right input will trigger click key +2. The click key and click program can
be accessed on the Song Mode MISC page.
Threshold (Thresh)
The Thresh parameter controls when the K2vx actually begins sampling incoming signals. If
you set it to a value of Off, sampling begins immediately when you press the Record soft
button. Otherwise the K2vx waits for the incoming signal to exceed a speciÞed threshold before
beginning to record. You can set the threshold from -90 to 0 dB, in 6 dB increments.
The K2vx has a pre-trigger featureÑthat is, the K2vx records the 3,000 samples immediately
before the point at which the threshold is exceeded. This prevents early transients from being
missed. This feature is automatic whenever the Thresh parameter is set to a non-zero value.
YouÕll want to adjust this parameter if your samples are missing these transients; the lower the
threshold, the more certain youÕll be of capturing every element of the signal. In some cases,
you may get better results if you set the Thresh parameter to a value of Off, then press the
