adstatus
Report and control audio driver settings
Description
Use the adstatus object to control Max audio settings.
Arguments
Controllable-settings:[symbol]
optional
The first argument is a symbol that specifies the setting to be controlled by the adstatus object. Some settings require an additional integer argument. The possible settings are:
cpu: Reports current CPU utilization.
cpulimit: Reports and sets the CPU utilization limit as a percentage from 0-100.
driver: Lists the available audio drivers and allows the current one to be changed.
info: Reports the number of function calls and signals used in the top level
input (Requires an additional argument specifying a logical channel number (used by the adc~ object) between 1 and 512): Lists the available audio driver input channels and allows the current setting to be changed.
iovs: Reports the available I/O vector sizes of the current audio driver and
latency: If supported by the audio driver, reports the input and output latencies of the driver in samples.
numinputs: Reports the number of input channels of the current audio driver.
numoutputs: Reports the number of output channels of the current audio driver.
option (Requires an additional argument specifying the option number (starting at 1): If the current audio driver uses the numbered option, reports the available choices for setting the value of the option.
optionname (Requires an additional argument specifying the option number (starting at 1): If the current audio driver uses the numbered option, the name of the option is reported.
output (Requires an additional argument specifying a logical channel number (used by the dac~ object) between 1 and 512): Lists the available audio driver output channels and allows the current setting to be changed.
overdrive: Controls the setting of overdrive mode (where the scheduler runs in a
sigvs: Reports the available signal vector sizes and allows the current signal vector size setting to be changed.
sr: Reports the available sampling rates and allows the current sampling rate setting to be changed.
switch: Turns the DSP on or off.
takeover: Controls the setting of scheduler in audio interrupt mode.
timecode: If supported by the audio driver, reports the current timecode value.

Messages
bang
In left inlet: Reports the current state of the setting. In many cases, messages are sent out the adstatus object's left outlet to set a pop-up menu object to display the current setting with a message. In these cases, the numerical value of the setting is sent out the adstatus object's right outlet. The exact behaviors are listed in the Output section below.
int
In left inlet: Changes the setting. In most cases, the number will correspond to the index of the menu item whose value was set by the adstatus.
message to- input
[int]
(inlet1)
In right inlet: If the adstatus object is used with the input, iovs, output, sigvs, sr settings, an int in the right inlet sets the value numerically rather than by using a menu index (see the or messages). For all other settings, a number in the right inlet behaves identically to one in the left inlet.
- input
[int]
float
In left inlet: Changes the setting. In most cases, the number will correspond to the index of the menu item whose value was set by the adstatus.
message to- input
[float]
loadbang
In left inlet: Outputs messages for umenu setup, and reports the state of the setting upon loading the patch. and messages are sent out the left outlet in order to set up a umenu object with a list of possible values, followed by a message to set the umenu to the corresponding index. The numerical value of the setting is sent out the adstatus object's right outlet. The exact behaviors are listed in the Output section below.
override
In left inlet: The word
, followed by a 1, turns on override mode for the setting associated with the object. When override mode is enabled, any change to the setting is not saved in the MSP Preferences file. The message turns override mode off. By default, override is off for all settings. However, some settings are specific to audio drivers and may not be saved by the driver.- flag
[int]

set
Out left outlet: When a
message is received or when the value of the setting that has a menu-style output is changed, the word , followed by a number with a menu item index (starting at 0) is sent out. Here are details of outputs from the left outlet for specific settings with menu-style outputs:sigvs

Out left outlet: For many settings, a series of messages intended to set up a pop-up menu object are sent out the left outlet when the reset or loadbang message is received by adstatus. See the message in the Input section for more details.
