1) How to get/excess the status of the "EQ on or off state" from the script?you can use EQOn property from the MJMixerAutomation object. see MJAutomation on explanation how to access the the object.
http://www.musicex.com/mediajukebox/DevZone/MJAutomation.htmlIt's also very useful to user
OnMixerChanged event to get notifications about Mixer changes.
2) How to one assign a button to activate the preset EQ setting?If you are referring to the EQ presets than currently it's not supported by MJ.
3) How to excess the status of "Mute/ un mute" from the script line?You can use MJautomation interface to access the state of the EQ.
Example:
MJAutomation.GetMJMixer().Mute = 1; // muted
if(MJAutomation.GetMJMixer().Mute == 0)
{
... do something
}
Hope that helps,
