If you attempt to trigger sample playback when no audio has been sampled, the
display will temporarily read:
SAMPLE BUFFER IS EMPTY
Rec
The Rec parameter (also found on Page 1 of Parameter Mode), determines how
recording of audio shall begin. This can be set to either 1 SHOT or GATED. No
matter which of these is selected, recording can begin by pressing the
[VALUE/ENTER] button while the Rec parameter is selected. Additionally,
recording can be triggered from a number of other sources, including: MIDI note,
footswitch or audio. This is determined by the Rec Trigger parameter (see page 4).
¥ When set to 1 SHOT, recording begins immediately once triggered (for example,
by pressing [VALUE/ENTER] button) and continues for the amount of time
specified in the Maximum Sample Length parameter (see below).
¥ When set to GATED and recording is triggered (for example, by pressing the
[VALUE/ENTER] button), recording of audio will begin and continue for as long
as the selected trigger source is detected or until the amount of time specified by
the Maximum Sample Length parameter has elapsed. If the Rec Trigger
parameter is not set to ENTER, the sample will play for as long as the selected
trigger source is detected. Example: If the Rec Trigger parameter is set to
AUDIO LEFT & RIGHT, recording will begin once audio is detected at either
the analog or digital inputs, depending on which is selected as the Input Audio
Source, and continues until audio is no longer detected or until the Maximum
Sample Length parameter has been reached.
Maximum Sample Length
The Maximum Sample Length (Parameter Mode, Page 2) is the amount of time the
Sampler effect will record audio once recording has begun (see previous section).
This can be set from 250.0 ms to 5000.0 ms (or 5 seconds), in .1 ms increments.
If the Maximum Sample Length parameter is changed, the Sample Buffer is erased.
