Section 8 — Sampling/Signal Source Parameters ASR-10 Musician’s Manual

2 Sampling Parameters

Sample

SAMPLE RATE

Inst•Track

Press Sample / Instrument•Track / Scroll using the Left/Right Arrow buttons

This read-only parameter shows the current system sample rate, as determined by the current

effect on the FX Select•FX Bypass page. If you attempt to edit this parameter using the Data

Entry Controls, the display shows either CURRENT EFFECT IS 30K or CURRENT EFFECT IS

44K.

Read-only Range: 29.7619 or 44.1000 KHZ

Now press the Right Arrow button again.

Sample

PRE TRIGGER

Inst•Track

Press Sample / Instrument•Track / Scroll using the Left/Right Arrow buttons

Range: 0 to 119 ms (30kHz) or 0 to 39 ms (for 44kHz)

This lets the ASR-10 start the sample before the sampling threshold is reached. The problem with

using a high sampling threshold is that you can sometimes chop off low-level information at the

beginning of the sound (below the threshold), making it sound clipped and unnatural. That’s

where the PRE TRIGGER parameter comes in.

The ASR-10 initially records the sample into a “buffer memory” of up to 119 milliseconds. You

determine the length of this buffer with the pre trigger amount. Now when you press Enter•Yes,

you get the benefits of being able to use a higher threshold without chopping off the beginning of

the sound.

After the sampling threshold is reached, the ASR-10 will “back up” the SAMPLE START by the

amount of the time selected in the PRE TRIGGER parameter. This allows sound just below the

threshold level (which would otherwise be lost) to be retained, as shown below:

Enter

Input signal Level

A pre-trigger amount of 10 to 20 ms should be adequate in most cases. You could set it higher to

ensure that you don’t miss any of the sound, or when using a very high sample threshold. In any

case, a little silence in front of the sound is better than clipping it short, because you can later

move the sample start forward to eliminate the dead space, and then truncate the WaveSample.

• Press the Right Arrow button again.
