The
"L"
(set levels) command is used to set the volume levels (0% to 100%) for each of the WAV channels.
Prop-1 Example
SEROUT Sio, OT2400, ("!AP16", %00, "L", 50, 50)
In this example, the AP-16+ at address %00 will change both the left and right channel levels to 50%.
"S" :: Set Playback Speed
Syntax:
"!AP16",
address
, "S",
speed
Reply:

The
"S"
(set speed) command is used to set the playback speed (50% to 200%). Note that the maximum
sample rate is 44.1kHz so a 44.1kHz file cannot be made to play faster.
Prop-1 Example
SEROUT Sio, OT2400, ("!AP16", %00, "S", 75)
In this example, the AP-16+ at address %00 will change the playback speed for subsequent files to 75%.
This will cause the pitch to be lower and the playback duration to be longer.
Status LED
The AP-16+ uses a multi-color status LED (S) to provide information regarding the operational state. The
table that follows illustrates steady and blinking patterns that you will see from the status LED under various
operational conditions.
